What do you think of when you hear the phrase “when pigs fly”? Do funny images of pigs with wings fill your mind? This common saying is used to express the idea that something happening is highly unlikely or even impossible.

For example, if you ask your parents when they’re going to buy you a brand new Ferrari, the answer might very well be: “When pigs fly!” You can spend a lot of your time scanning the skies for flying pork, but your chances of seeing a flying pig are about the same as seeing a shiny new red Ferrari in the driveway.

So why pigs? And why flying? Why couldn’t people just say, “Never. Not a chance!”?

People have used colorful phrases for centuries to get a particular message across. We usually call such phrases “figures of speech.”

These phrases convey a sense of humor and allow people to put a positive spin on things without seeming so negative. Instead of simply saying “no,” someone can communicate the same message in a way that makes it sound — technically — possible.

After all, couldn’t pigs fly one day? Granted, their weight and lack of wings weigh heavily against their chances of taking flight. Plus, there’s the whole question of desire. Do pigs have the urge to fly? Without that internal motivation, the seemingly-impossible will probably never become possible.

No one is certain exactly who developed the phrase “when pigs fly.” An old reference to pigs flying appears in Lewis Carroll’s Alice’s Adventures in Wonderland. However, scholars believe Carroll may have picked up the phrase from the Scottish, who allegedly had been using the phrase for a couple hundred years.

They may be right. John Withals’ 1616 English-Latin dictionary lists the proverb “pigs fly with their tails forward.” That similar phrase was apparently used back then as a clever reply to people who made overly-optimistic statements.

There are also those who believe the phrase may have gotten its start in America. Long ago, before the Industrial Revolution, farming was the primary occupation for most Americans. It’s not surprising that many common sayings that developed back then had an animal or farm background.

For example, long ago, farmers used to transport pigs for slaughter along rivers on small barges. If it was foggy, people on shore could only see the pigs’ heads above the fog. This made them look like they were flying through the clouds. This might have given rise to the popular saying.

Other countries also use animals in figures of speech to represent the impossible. For example, many countries use the phrase “when cows fly.” Other countries, such as France and Spain, use phrases like “when frogs grow hair” or “when hens grow teeth.”

  1. We loved the pig clip. We thought it was hilarious! Our parents might answer “when pigs fly” if we asked; to have a hundred dollars, for a brand new room, to drive their car, for a pet pigeon, or for a new computer.

    We think tomorrow’s wonder may be about when you button your pants, when your brother gets on your nerves, or when your sister gets on your nerves.

    • Hello to our Wonder Friends in Ms. Bayko’s Class… oh should we say “oink!”?

      We like the different scenarios you presented — we bet if we asked our parents to drive their car, they would respond “when pigs fly”, too! :)

      Thanks for visiting us at Wonderopolis today! We love when you share your ideas and guesses with us– it’s so much fun to learn about Wonders of your own! :)

  2. When will pigs fly is a funny term and I’ll admit that it is used around my house a lot, plus sometimes in my past years someone’s asked for candy and the teacher would say: “If pigs fly!”

    I think that tomorrow’s wonder of the day will be either a robot or an old-fashioned video game in an arcade.

    Happy pickles!

    • Hey there JC! Thanks for letting us know that the term “when pigs fly” is used in your house, too! We think your teacher has a great sense of humor, too!

      We’re glad you commented on today’s Wonder, JC, and we are WONDERing if you’ll help us learn something new today… what does “Happy Pickles” mean? Perhaps there’s a new holiday or greeting that we don’t know about yet! Our Wonder Friends would LOVE to learn more about it! :)

    • WOHOO, we’re glad our Wonder Friends in Mrs. Jones’ Class are starting the day with a smile on their faces! That’s how we like to start the day, too! Thanks for joining in the fun today– have a WONDERful Wednesday! :)

  3. The video was so funny! We loved it! We think it was the best video yet! We have watched them all year long. It is one of our favorite parts of the day.

    We think our parents might say “When pigs fly!” when we ask:

    “Can I have $100.00?”
    “Can I have a new iPad?”
    “Can we live in a mansion?”
    “Can I have a spaceship?”
    “Can I have a 3DS?”
    “Can I have another dog?”
    “Can I stay up all night on a school night?”

    Thanks for jumpstarting our minds every morning!

    Mr. Lensman’s Class

    • WOW, we’re so proud of our Wonder Friends in Mr. Lensman’s Class– you have formed a WONDERful list of questions that might receive the response “When pigs fly!” :)

      Thanks for sharing your comment with us- we’re glad today’s video and Wonder made you giggle and smile! We hope our Ormie gets a cookie soon! He tried so hard! :)

    • Hi there, Wonder Friend Johnathan– we’re glad that today’s Wonder made you smile! We hope you and some of your friends, classmates or family members will watch our Wonder video again– we love Ormie the pig! :)

  4. I think this video was funny and entertaining. I love watching the pig try and fail. He makes me laugh especially when the jar fell on his head and he couldn’t eat the cookies. I hope there’s a part 2!

    • Hello Tanner! Today’s Wonder video was LOTS of fun– we’re so glad you enjoyed it! Poor Ormie the pig was doing everything he could to get to those cookies!

      We don’t have a part 2 to share with you, but we Wonder if you can do some research of your own about “Ormie Pig” and his WONDERful creators! :)

  5. I thought this video was hilarious and I would think that the creater should make more of these kind of videos!!!! This was the best video of my life!!!! Thank you for making this video!!!!!!!!!!!! Hope you make another one!!!!!! :) ;) :) ;)

    • We agree, Hannah, we think today’s Wonder video was fantastic to watch! We can’t take credit for creating the video, but we’re glad to share Ormie the pig with you!

      We Wonder if you’ve ever heard someone respond to a question you asked with “when pigs fly”? :)

    • HOORAY, that’s SUPER news from our Wonder Friends in Ms. Haley’s Fifth Graders! We are so proud of all of you for WONDERing with us AND connecting flying pigs to your science lesson! WAY TO GO! Have a WONDERful Wednesday! :)

  6. We thought today’s wonder was hilarious. We LOVED Ormie! We talked about making inferences with this video and also completed a story map… amazing since there were no words! We are learning about figurative language and will be focusing on idioms and cliches next week. This was a perfect start to that study! Olivia’s mom often uses the phrase “on a slow boat to China” with her.

    We think tomorrow’s wonder will be about robots, the movie iRobot, mother’s getting mad at their children because they’ve “pushed their buttons”. We think it is WONDERful that JC was one of the first commentors!

    • Way to go, Wonder Friends in Mrs. Ski’s AM Class! Your story map sounds WONDERful! :)

      Today’s Wonder sounds like a perfect introduction to your language arts lessons next week– WOHOO! Olivia’s mom has another great example of figurative language!

      We like your very creative guesses for tomorrow’s Wonder! Great work using your imaginations! :)

  7. Dear Wonderopolis,
    We really loved the video. It was so hilarious and crazy! What gave you the idea to write this article?
    Mrs. Johnson’s class

    • Well thank you, Wonder Friends in Mrs. Johnson’s 4th grade class! We LOVE to hear that today’s piggly-wiggly Wonder made you giggle!! :)

      One of our Wonder Friends asked quite a silly question and another friend responded, “When pigs fly!” We all looked at each other and thought… I WONDER where that expression came from! Have a WONDERful Wednesday! :)

  8. Today, we practiced how to use “when pigs fly”. For example, Natalie asked for an airplane and we said, “When pigs fly you’ll get an airplane”.

    • He he, we think that’s a great response to Natalie’s request! Nice work Wonder Friends in Mrs. Utter’s Kindergarten Class! Keep up the SUPER WONDERing today! :)

  9. Good morning, Wonderopolis!

    Pigs really do fly in Cincinnati, Ohio http://www.mpna.com/fpqrp/pighist.html In fact, there is even a big race called, The Flying Pig Marathon.

    • YOWZA, our friends in Mrs. Phillips’ WONDERful class are hard at work today! We are so impressed with all your creative sentences that include the phrase “when pigs fly”! :D

      Also, thank you for sharing the information about the origin of “flying pig” and the half and full marathon that takes place in Cincinnati! How very COOL!

    • We bet you’ll find out if you check out today’s Wonder, Michael! We bet the video will put a smile on your face, too! Let us know what you think after reading our oink-tastic Wonder! :)

    • Hey there, Anna! We’re glad you’re WONDERing with us today! You’re right, pigs don’t fly in real life, but in today’s Wonder video, Ormie the pig sure wishes he could fly! We hope you have a SUPER day… thanks for commenting! :)

    • Hi there, Marco! We’re sorry to hear that today’s Wonder wasn’t one of your favorites, but we appreciate your comment. We hope you’ll come back to Wonder with us again soon! Have a SUPER day! :)

  11. I think today’s wonder was great!! I loved the video and the article. They were so funny. I hope you can do a wonder on dogs sometime! Thanks!!:) ;)


    • HOORAY, Wonder Friend Piggs! We hope you and your Wonder Friends share today’s oink-tastic Wonder with your teacher! It’s made all of us at Wonderopolis giggle with delight! :)

    • What a SUPER creative answer to today’s Wonder Hailey! We’re so happy you’re using your imagination with us today! HOORAY! :)

    • Hey there, Wonder Friend Blakeleigh! HOORAY for today’s piggy Wonder! We think Ormie is one creative pig, even if he does break the trampoline! Have a SUPER day and thanks for visiting Wonderopolis! :)

  12. Thank you Wonderopolis for making us giggle and laugh this morning!
    We made up our own funny sayings that we could say to people-

    When lizards have beards!
    When people have frog skin!
    When the moon turns purple!
    When horses fly!
    When kittens fly!

    We think our parents will say “When pigs fly” when we ask them these questions-

    When will I get a new iPad?
    When will you buy me a real movie theater?

    • WHOA! Mrs. Thomas’Tigers are on a roll! Thank you for sharing all your phrases! We bet our Wonder parents would also respond to your questions the same way– “when pigs fly!”

      Thanks for WONDERing with us today! :)

  13. We thought that today’s wonder was hilarious. JD thought that Ormie was very determined to get the cookies. Kaden thought Ormie was funny. Bella thought it was a little porky smelling (like fishy). Kaylyn thought it was hard for Ormie to eat the cookies with the jar on his head. JK thought it was funny when he was using a chain saw to cut the floor. Jacob thought it was funny when he tried to use the airplane.

    We think tomorrow’s Wonder will be about buttons, getting mad, robots, old fashioned video games, remote controls, or making your parents mad.

    Pigs will fly when pigs fly.

    • Today’s Wonder gave us the giggles, too! Our Wonder Friends in Mrs. Ski’s PM Class are using their AWESOME imaginations by sharing their thoughts about today’s Wonder! Nice work!

      Thanks for getting creative and posting your guesses for tomorrow… we can’t wait to Wonder with you again! We hope it will be before ‘pigs fly!’ :)

  14. Well I’m back with some facts about when pigs fly, from what I’ve read and this is true when pigs do fly bad things are supposed to happen like when your on a date a pig will come and take the person you’re dating.

    • WOW, thanks for sharing that WONDERful information with us! We’re glad you did some research of your own, Wonder Friend T! We hope nothing bad happens to you– we wouldn’t want you to have to use the term “when pigs fly” to describe your day! :)

  15. Today we started to celebrate Wonder Wednesday. The video was really funny and spectacular. We learned about idioms when we were reading: Capture the Flag. Other phrases like when frogs grow hair, hen grow teeth were new to us. In our art class, we are making “piggy banks” and some of the banks have wings. We started building our own wonder books to use every Wednesday. We think tomorrow’s wonder might be about elevators or another idiom about when your buttons get pushed and you are really mad.

    • Oh my goodness, our great Wonder Friends in Mrs. Caplin’s Class are really on a roll! We LOVED the words you used to describe today’s video: funny, spectacular! How appropriate!

      We think your Wonder books sound like a SUPER way to put your imagination, writing skills and creativity to work! All of you will be Wonder authors by the time you finish! YIPPEE!

      We can’t wait to see you soon… tomorrow’s Wonder is going to be STELLAR, just like your guesses! :)

  16. That video clip was so ridiculously funny. He tried every single way to get the cookies from slingshot to rocket to a chainsaw. The ending was the funniest of all because he finally got the cookie but as he is about to take a bite, the jar landed on his head.
    ha ha ha ha ha!!

    • Alright, we’re glad that today’s Wonder video put a smile on your face, Tyler J! We think that Ormie the pig is a determined animal, but poor Ormie never tasted his delicious cookies! You did a great job summarizing today’s video clip– nice work, Tyler J! :)

    • HOORAY Meagan! We’re glad that you and your WONDERful classmates were giggling after watching and reading today’s Wonder! We hope you’ll visit us at Wonderopolis very soon! Have a SUPER Wednesday! :)

    • HOORAY for our Wonder Friends in Mrs. Romanowksi’s Class today! We are glad to hear that Ormie the Pig made you chuckle! Thanks for WONDERing with us today! :)

  17. Hey it’s Avery again!!! I’ve heard the term “when pigs fly” alot but never have I seen a pig trying to get cookies off the fridge. I wonder if a pig has ever flown it would be incredible if they have before and I hope you will get back to me soon thanks for your time .

    From: Avery

    • Hey there, Avery! We’re glad to hear that our oink-tastic Wonder put a smile on your face! We think it would be amazing (but quite rare) to see a pig fly, but you never know…! :)

  18. I love that phrase and when I was in third grade I was obsessed with cars and asked my parents for a Ferrari and they said “when pigs fly”.

    • WOW, that’s quite a grand request, Will! We bet your parents have a great sense of humor! We hope you keep WONDERing and learning about different type of cars, like the Ferrari! :)

  19. Hi I love animals so I went to this website then the first thing I saw was when will pigs fly so I clicked then I saw the video and it was HILARIOUS!!!!!!!!!!!

  20. I really liked today’s wonder of the day. It was interesting and the video was very funny. I new about the term when pigs fly, but not when hens grow teeth or when frogs grow hair or when cows fly.

    • Thanks for sharing your comment about our oink-tastic Wonder, Velma K! It was fun to learn some new figurative speech phrases with you today, including “when hen grow teeth!” :)

  21. That was the most hilarious video I have ever saw on wonderopolis so far!!! I hope you put a another video like that on wonderopolis again!!!

    • Thanks so much, Galifinakis! We’re excited that our oink-tastic Wonder was right up your alley! Have a SUPER day, Wonder Friend! :)

    • We bet you’re right, Hannah! We think that has something to do with the phrase “when pigs fly”– maybe that’s why it’s so popular! :)

  23. That video was so funny it had my whole entire family laughing. Today’s wonder was amazing I loved it so much! see you tomorrow.
    Sincerely Danielle :)

    • Thank you, Wonder Friends in Mrs. Marshall’s Class! We are glad that you were laughing with us– Ormie is a funny pig! :)

  24. I think that the pig thing isn’t good. I think that pork is supposed to stay on your plate. Maybe cows because cow get in trees because of tornados.

    • That’s okay, Aaron! We respect all our Wonder Friends’ opinions and comments here at Wonderopolis! We are glad that you enjoyed the video, too! :)

    • Hey there Bob, thanks for letting us know how you feel about pigs! We hope you learned something new from our Wonder… have a terrific Thursday! :)

    • We’re glad you mentioned a Wonder of your own, Panda! We are so excited that you are dreaming up Wonders of your own– that makes us smile! It takes some time to create Wonders here at Wonderopolis, but we are happy that you nominated one of your own! Thanks for reminding us, Panda! :)

    • He he, we think that’s a funny way to use the term “when pigs fly”, Jackson B! We like the other idiom you suggested, “’til the cows come home”! We think that one refers to someone who stays up late…! Have a SUPER day! :)

  25. The movie was really funny. The information was great. We are doing a school project on it because it’s a cool topic. Thanks!!!

  26. So your saying pigs can’t actually fly someday? Aw man! But is it actually possible someday to have pigs flying around in the future? It would be soooooooooo awesome I want A FLYING PET PIG IN THE FUTURE!!!!!:3 :D
    Katherine Wang :)

    • Thanks for sharing your comment, Katherine! As of right now, pigs cannot fly. However, who knows what the future holds? We bet a pet pig would be fun, but a LOT of work! Thanks for WONDERing with us today! :)

    • Hey there, Bananapeel81! We think, even though it was a stuffed animal, it’s cool that you did see a pig fly! We like your creativity! :)

  27. I teach Technology Engineering and Design for students in a NC high school. Part of the course involves problem solving. I plan to use this video as a humerous introduction to the concept of problem solving. I thing even my high school students will enjoy the clip.

    • Hi there, Michael! Thanks for sharing your comment with us– we’re delighted that you enjoyed Ormie the Pig as much as we have! Thanks for letting us know that you plan to begin your lesson plan with the video– we think everyone will get a chuckle out of it! :) We look forward to hearing how it went! :)

  28. We loved the #828 one today! It made us chuckle! Then we watched the pig one, that one we laughed our butts off. We are wondering what it will be tomorrow.

    • Hi there, Wonder Friends in Mrs. Atkinson’s book club! We’re glad to know that you’re laughing with us! Today’s Wonder video, as well as “When Will Pigs Fly” really make us chuckle, too! Thanks for WONDERing with us, and we hope to see you soon! Perhaps you can visit the “Wonder What’s Next” section; you can share your guesses with us! :)

  29. Dear Wonderopolis,

    Your new friend,

    • Hey there, piglover! We’re so glad you enjoyed our Wonder about your favorite subject– pigs! Ormie sure is oink-tastic! Thanks for sharing your comment with us! :)

  30. I loved the “When Will Pigs Fly’ video. I liked it when the pig used a slingshot to try to get the cookies when he could have shook the frige to get them. It was the funniest video I have ever seen.

    • We’re so glad that Wonder video made you smile, Logan! We think it’s great that you’ve been WONDERing about other ways Ormie the Pig could have moved the fridge, too! Nice work! We hope you have a WONDERful day! :)

  31. Dear Wonderoplis,
    I love this wonder. I’ve been studying pigs and I think it would be great to bring up the term “when pigs fly”. One question I have is why do they say “When PIGS fly”? It could be when dogs fly or when cats fly.

    Can’t wait to read more!

    • Hey there, Hayley, we’re glad to hear that this Wonder is connected to what you’ve been studying! We think it’s cool that you’ve been WONDERing about other animals that would fit for this phrase, too, like dogs or cats! Thanks for sharing your comment today! :)

  32. It is very interesting my favorite part was when the pig cut around the fridge and it fell through the floor and landed on the next floor.

    • We’re glad you’re WONDERing with us, Irish! Thanks for telling us about your favorite part in our oinktastic Wonder! Ormie the pig really makes us smile! Thanks for sharing your comment today! :)

  33. I love this video. At first I didn’t know what the phrase when pigs fly meant now I do! Thanks so much for this video!

    • HOORAY, we’re so glad you learned about the phrase “when pigs fly” and you smiled while WONDERing! HOORAY! :)

    • We’re so happy this oink-tastic Wonder made you smile, Zoe and Lexis! Thanks for joining Wonderopolis and Ormie the pig as we learn about pigs… and if they really CAN fly! :)

  34. That is so funny! I really liked the end when the pig was just going to eat the cookie but the bowl landed on his head it was hilarious!! =)

    • Hey there, Ellen and Kaden! HOORAY for WONDERing! Thank you for sharing your comments about Wonderopolis and our piggy Wonder! We Wonder if you have ever heard or said the expression “When pigs fly”? :)

  35. If pigs fly, it would be like flying bacon in the sky!

    By the way, can you post a video about the greek gods? I searched mythology and i didnt see it.

    • Flying bacon in the sky?! What a sight THAT would be! Thanks for your suggestion about a possible future Wonder about Greek gods! Hope to see you again soon, Wonder Friend Chamani! :)

    • We’re glad to know you have been laughing with Ormie the pig today, Alyssa! While we cannot take credit for the awesome Wonder video, we sure did enjoy the animation! :)

    • Hey there, Cool5, do you read us? It’s Wonderopolis signing in! Thanks for sharing your comment about Ormie the pig and his adventures in the kitchen! All he wants is a cookie! We like thinking about how we can use the phrase “when pigs fly”… you can check out some of the comments from other Wonder Friends- there are some great ideas!
      Thanks for visiting us today, Cool5! This is Wonderopolis, signing out! :)

  36. At school today I showed my comment to Conner my classmate. He was like did you post that and I was like Yeah. I love you guys!

    • How cool, Wonder Friend Alyssa! We love having an awesome Wonder Friend like you! We hope you and Connor will come back to Wonder with us again! :)

    • Hey there, Justin! We bet Ormie the pig wished he could fly to get to those cookies! Thanks for sharing your comment! :)

    • That sure would be cool, Wonder Friends Gaya and Yui! We can only imagine if we looked up and we saw pigs and birds flying beside one another! How neat! :)

  37. My parents has used the phrase “when pigs will fly” when I asked them if I could get a bunny for my birthday. They also said that my dog might eat it.

  38. I LOVE this video and you guys are awesome! But I have a question for you guys can you guys make more animation videos?

    • Thanks for WONDERing with us today, Alyssa! We are so glad you enjoyed our oink-tastic Wonder! While we LOVE animated videos, we don’t always create the videos that are part of the Wonders of the Day! Thanks for being a great Wonder Friend and sharing your suggestion! :)

  39. Hey guys thanks for replying to my wonder. Hope you make more animated videos. Plus I have you an idea for tomorrow’s wonder it`s called Do the Beatles have a secret talent? And make it an animation video of the Beatles doing a secret talent. You can choose the talents. bye!

  40. Hey guys! I just saw the comment you sent me at home. You are right WONDER 684 is perfect for me. I can’t watch it right now because I’m sending this from my iPod touch and it won’t let me watch that video. ;( I promise I will watch it at school tomorrow. Bye. ;)

    • Hey there, Alyssa! We are glad you’re WONDERing with us, and we look forward to hearing from you after you view the Wonder video at school! Have a terrific Friday, Wonder Friend! Keep up the great work! :)

  41. Hi guys I am at school reading your comment and can you name some funny animated videos you made? But don’t name carrot crazy, ormie, and monster making kid whatever. Anyway please name the animated videos by 2:30 please. Bye. :)

    • Good afternoon, Wonder Friend Alyssa! We are glad you’re WONDERing at school with us today! We are so lucky to have WONDERful friends who share their very own videos with us… so Wonderopolis doesn’t create or animate any videos right now. Thanks for asking, Alyssa! :)

  42. Hey guys, I was thinking you guys could make a video about me like I’m a 9 year old girl who has light brown hair and loves fashion and you can call the video Do you know Alyssa Wacker? What do you think? Bye. ;)

  43. Hey guys, HAPPY MAY DAY!!!!!!!!!!!!! I am so happy to send you a comment today. Silly wonderopolis, you did not reply to my comment. Well bye. HAPPY MAYDAY! ;)

    • Hey there, Wonder Friend Alyssa! We love that you’ve been sharing so many comments with us– you’ve got an awesome imagination! We’re sorry we didn’t respond to your comment above, but we Wonder if you can create a Wonder all about yourself? Or perhaps you can create a Wonder all about someone close to you, like a family member or friend? Happy May 1st! :)

    • We’re so glad you liked WONDERing with the help of Ormie, Alex! We wish Ormie could fly, too– he really wanted to get to those cookies! :)

    • HOORAY, that’s WONDERful to hear, Maddie M! We’re glad you learned something new from this Wonder, and you’ve been giggling, too! We are still laughing because of Ormie the pig. He tries to hard to fly and we can understand why– those cookies look delicious! :)

      Do you, your family, or your teachers ever use the term “When pigs fly”? What other funny sayings can you think of? :)

    • Hey there, Issie! Thanks for sharing your comment with us today! Pigs sure do have fun, especially when they are in mud! Have you ever seen a pig in real life, Issie? :)

    • That’s right, Micah! Pigs can’t fly no matter how hard they try. We love WONDERing together, Wonder Friend! Have a WONDERful Day! :-)

  45. I asked for a Wii U a week before Christmas,and my grandma Clark heard that they said “When Pigs Fly”,my grandma bought me one.Ahh the burn.

    • We’re so glad to have you back WONDERing with us, Wonder Friend Graham! That’s great that your grandma bought you your very own Wii U! Isn’t it WONDERful when we get things that we never thought we’d get? We hope you have a WONDERful Wednesday! :)

  46. We think that this is really funny. Like in real life pigs will never fly. We learned the saying “when pigs fly” is a funnier way to say “no.” We don’t always want people saying “no” to us. Someone could say “when pigs fly” and that would be a better way to say it.

    Thank you.This was interesting! -Room 13 kids

    • That’s a great point, Room 13 kids! It’s nice to have creative and funny ways to say things. Thanks for sharing your comment with us! :)

Try It Out

“It will never happen.” “Never.” “Ever.” That’s the message you want to get across. You could say, “When pigs fly!” But that’s been used before.

Today, come up with your own unique phrase that means “Never!” Be creative. Use your imagination. Dream up a phrase that paints a vivid picture in the mind of an event or scenario that will never, ever happen.

When you’re finished, share your phrase with your Wonder Friends on Facebook. You never know when your phrase might catch on and become a common saying!
