->''"Holy crap!! They TALKED! They actually '''TALKED!''' The Apocalypse has finally begun! Pigs are learning how to fly! Satan is skating his way to work, and I'm pretty sure that I just became a monkey's uncle!"''
-->-- '''WebVideo/TheNostalgiaCritic''', upon hearing WesternAnimation/TomAndJerry talking during his review of their BigDamnMovie.

This is what happens when FinaglesLaw, TemptingFate and the human tendency to spout hyperbole when a simple "never" would suffice all get together and have a drunken party with [[HilarityEnsues hilarious results.]]

When circumstances conspire to incite someone to exclaim that something would happen if and only if something everyone ''knows'' is impossible occurs -- "when [[FireAndBrimstoneHell Hell]] freezes over" (nevermind that according to ''TheDivineComedy'', the final level of Hell ''is'' frozen over) and/or "when pigs fly!" and/or "[[BreadEggsBreadedEggs when pigs fly over frozen hell!]]" -- you can bet that by the end of the episode we will see pigs soaring majestically over the landscape or {{Satan}} running ski slopes while sipping hot cocoa.

!Examples:

[[foldercontrol]]

[[folder:Advertising]]
* A Canadian lottery commercial references the trope. Two people are in the lunchroom at work. One looks out the window. "Hey, flying pig." And indeed there is a flying, or rather hovering, pig outside the window, along with a "Not possible" caption on the screen. "Hey, I won!" says his coworker, checking his lottery ticket. "Possible" shows on the screen.
* There's a Red Bull commercial featuring this. (Boy wants to go to a 'gentlemen's club', told only if pigs fly, cue the pigs.) The Italian (European?) version has the "flying donkey" variant. In the ad, the pigs/donkeys have drunk Red Bull, of course.
* A recent Burger King ad played with this, when a customer notices an ad for bone-in fire-grilled ribs and expresses disbelief until a winged pig confirms it's true. Namely, a winged pig driving ''a truck''. The customer brings it up, and the pig explains that [[MundaneFantastic he's moving out of his mother's basement, and needs the truck to carry his stuff]].
* An ad for GEICO has a pig[[note]]specifically the pig from the Wee Wee Wee spot[[/note]] using his GEICO mobile app on a plane in preparation for takeoff. The flight attendants say, "I'll believe that when pigs fly," at which point the pig turns to the guy next to him and says, "Did she seriously just say that?"
* There's a Bush's baked beans ad where the talking dog asks the human if he can sell the secret family recipe. The guy replies "sure, when pigs fly". Cut to the dog talking to a pig with improvised wings getting ready for takeoff. "Now, just buzz around the house a couple of times and that should do it."
* A 2015 Super Bowl commercial for Doritos showed a young boy asking an older guy, possibly his brother, if he can have Dorito. His brother tells him he can have one "when pigs fly." The boy is then shown working on some plans and then the scene changes to a pig flying on a rocket, after which the kid is given a Dorito. The commercial shows the kid then patting the pig on the back, it having apparently come out of the experience [[NoAnimalsWereHarmed no worse for the wear]]. "Good boy."

[[folder:Comics]]
* ''ComicStrip/{{Dilbert}}'': During a brief period when Dilbert had a steady girlfriend, Phil the Prince of Insufficient Light barges in:
-->'''Phil''': [[GoshDangItToHeck Heck]] just froze over.\\
'''Dilbert''': This is ''not'' my fault!\\
'''Phil''': (points over his shoulder to a pair of flying pigs) Tell that to ''them''.
* In ''LibertyMeadows'', which Frank gets a date, it cuts to hell where it's snowing. A confused Satan (who looks an awful lot like UsefulNotes/RichardNixon) says that this either means [[GermansLoveDavidHasselhoff Germans finally hate David Hasselhoff]] or Frank got a date.
* In ''{{Zits}},'' Jeremy's dad watches a flock of pigs flying by. He looks surprised until his wife tells him Jeremy cleaned out his bathroom without being threatened.
* ''{{Garfield}}'': Consciously averted by Garfield: "Don't get me wrong, I love dogs. I'd never hurt a dog. And if I'm lying, may lightning... *pause* ... [[GenreSavvy strike the dog next door]]." (Crack) "Yip!"
** [[http://www.garfield.com/comics/vault.html?yr=2010&addr=100704 Jon made a drawing of a pig]] (which just so happens to look like [[ComicStrip/USAcres Orson]]). Garfield made a better drawing. When Jon complained that pigs didn't have wings, Garfield said they'd have before Jon outdrew him. Also counts as a ShoutOut as that strip ended with Garfield calling Jon [[Creator/PabloPicasso "Pablo"]].
* The ''Franchise/{{Star Wars|Expanded Universe}}'' one-shot comic ''[[ComicBook/StarWarsTales Force Fiction]]'' has this trope mixed with [[BankRobbery Ban... err... "Restaurant" robbery.]] When Yoda and Mace Windu were, in an interesting case of RoleReversal, debating whether Anakin should be made a Jedi or not at a restaurant, Yoda, while chewing out Windu for even suggesting the idea to let Anakin receive the late Qui Gon Jinn's lightsaber, much less train him as a Jedi, mentions "When Banthas fly, my Jedi friend." One panel later, a "flying bantha" of sorts (a repulsorlift skiff designed in such a way that resembled a bantha) crashes through the window of a restaurant, with the pilots declaring that they are commiting a robbery, demanding that everyone put their credits on the table and raise their hands.

[[folder:Fanfiction]]
* At one point in the ''WesternAnimation/CodenameKidsNextDoor'' fic, ''[[https://www.fanfiction.net/s/8026382/1/Diplomatic-Impossibility Diplomatic Impossibility]] that Numbuh 4 has the same chances of getting an A+ in school as flying mutant space pigs attacking the KND moon base. At the end of the story, 4's essay on the customs of the obscure nation the mission took place in nets him that grade, and the moon base quickly braces itself for impending space pig attack.

[[folder:Film]]
* In ''{{Dogma}}'' Jay propositions Bethany, and she turns him down. So he says, "What if the world was about to end?" and she agrees so he'll shut up. Fast forward all the way to the end of the movie, when Bartleby is close to unmaking reality, and Jay tries to make good on their "deal."
* In Disney's ''Disney/AtlantisTheLostEmpire'', this trope appears in the backstory. Whitmore reveals to Milo that he and Milo's grandfather Thaddeus had had a [[TheBet bet]]: If Thaddeus ever found the elusive Shepherd's Journal, Whitmore would not only finance the expedition to find Atlantis, but he'd also kiss him full on the mouth. Whitmore then shows Milo a photograph of himself and Thaddeus, both looking thoroughly [[{{Squick}} squicked]] out.
---> '''Whitmore:''' Imagine my embarrasment when he ''found'' the darn thing.
* Subverted in ''AngelsInTheOutfield''. Roger's dad tells him that he'll take him out of foster care and they'll be a family again "when the Angels win the pennant" -- meaning never (the Angels were in last place in the standings at the All-Star Break, a little past the halfway point of the season), only Roger [[InnocentInaccurate takes it literally]] and [[AchievementsInIgnorance makes it happen]], with the aid of supernatural beings. [[TearJerker His dad leaves him in the custody of the state anyway.]]
** In the ''{{Website/Cracked}}'' spoof, Roger's friend quips "[[TakeThat It could be worse, he could've said the Padres!]]"
* ''Film/MontyPythonsTheMeaningOfLife''
--> '''General Craham Chapman:''' It's all very well to laugh at the military, but when one considers the meaning of life, it is a struggle between alternative viewpoints of life itself. And without the ability to defend one's own viewpoint against other perhaps more aggressive ideologies, then reasonableness and moderation could, quite simply, disappear! That is why we'll always need an army, and may God strike me down were it to be otherwise. ''[Is promptly struck by lightning]''
* In ''Film/TheWolfman2010'', Dr. Hoenneger is lecturing about the strapped-down Lawrence Talbot remarks that his patient can no more transform into a monster than he, the doctor, can sprout wings and fly out of the window. Sure enough, when Talbot transforms and breaks loose, he invokes DestinationDefenestration on the shrink.
* In ''ItsAVeryMerryMuppetChristmasMovie'', Miss Bitterman is threatening the Muppet Theater with foreclosure, and says they will raise the money to save it "when pigs fly." In swoops Miss Piggy, still suspended from the cables from the act they had been practicing. After a {{beat}}, Bitterman adds, "For the record, I consider that a coincidence, and not a sign from God."
* In ''Film/BruceAlmighty'', Bruce-turned-God confronts the hoods who had beat him up the previous day, demanding an apology, to which one replies:
-->'''Hood:''' Okay cool, man, the day a monkey comes out of my butt is the day you'll get your "sorry". \\
'''Bruce:''' What a coincidence, because that's ''today''.
** [[ExactWords And sure enough]]....
* ''[[Film/NannyMcPhee Nanny McPhee Returns]]'' has flying pigs (referential of a similar gag in the first film in which "snow in August" is used to describe something supposedly impossible that happens thanks to Nanny's magic).
[[/folder]]

[[folder:Jokes]]
* [[http://ranneliike.net/keskustelu.php?act=rthrd&grpid=7&thrdid=3648 This]] joke about Finland. The end is obsolete now. Another version talking about {{Russia}} lasted until 2008, and, finally, {{Norway}} worked until 2009. Has Europe run out of northern countries yet?
** Actually, the joke works with Northern Canada. Maybe even southern Canada, as long as you're not too close to any of the Great Lakes. Only problem is the crazy hot summers in the southern parts...
** Several of the Midwestern states have variants on it. Simply replace "Koskenkorva" with "keg" and "Eurovision" with "Super Bowl" (if you're in Michigan, Minnesota, or Ohio) or "World Series" (Wisconsin).
** The current version replaces Eurovision with Football World Cup. WeWait...

[[folder:Literature]]
* In the Creator/DianaWynneJones book ''Literature/DarkLordOfDerkholm'', an elf makes a sarcastic prophecy that he'll find his brother "when pigs fly". As it happens, the main character is a wizard who breeds flying pigs...
* The book ''Pigs Don't Fly'' by Mary Brown has it written in the title itself, [[spoiler: and a pig actually does fly, [[OurDragonsAreDifferent only it's not a pig]].]]
* Inverted in Dante's ''Inferno'': Satan is imprisoned in ice. When it melts, it's gonna get bad.
* In Piers Anthony 's ''IncarnationsOfImmortality'' series, a minor character says she'll surrender to some pirates "when God kisses Satan and all the Incarnations applaud". Guess what [[ItMakesSenseInContext happens]] at the end?
* ''PercyJacksonAndTheOlympians'' has the Clazmonian Sow, a pig which not only flies, but also has toxic breath.
* In the ''Franchise/DisneyFairies'' book "A Snowy Surprise," Vidia claims she'll appreciate other talents "when it snows in Pixie Hollow" (where it's [[ItsAlwaysSpring always spring or summer]]). One day, however, it does snow and all the fairies, including Vidia, enjoy playing in the snow. Rani points out to Vidia that she must appreciate another fairy's talent now, since the snow was all the work of the water fairies.
* In ''Literature/MemorySorrowAndThorn'', [[RebelliousPrincess Miriamele]] tells Cadrach she will trust him again "when the stars shine at midday!" [[spoiler:Of course, during the Storm King's attempt to return to the world at the end, the midday sky appears as the night sky did on the night of his death, and Miriamele trusts Cadrach enough to walk across his invisible magic bridge during his HeroicSacrifice.]]
* A variant in ''Chrome Circle'', by Creator/MercedesLackey and Larry Dixon, when Shar insists to herself that she had purely practical and impersonal reasons for expending magical energy to Heal Tannim ... and then admits mentally, "And pigs were certainly flying in tight formation over [=LaGuardia=] at this very moment."
* In ''[[{{Valdemar}} By The Sword]]'', teenage aspiring mercenary Kerowyn ruefully thinks that finding life with a man who would love her and let her be [[ActionGirl herself]] would be as likely as her horse talking to her. Guess what happens a couple of decades later after her [[PrivateMilitaryContractors merc unit]] [[LineInTheSand went beyond the terms of]] the contract they accepted from {{Valdemar}} and her [[CoolHorse Shin'a'in Warsteed]] got killed under her in the middle of a fight....
* The protagonist of the ''Literature/GarrettPI'' series frequently references this expression about his own hyperbole, even though he lives in a fantasy world where winged pigs might hypothetically be possible.
* Justified in the Emily Rodda novel ''Pigs Might Fly''. The story is set in a parallel universe where a weather pattern called the Unlikely Events Factor, or UEF Storm, causes all manner of unlikely events, most commonly flying pigs. On one occasion, the government foolishly attempted to stop these by tying pigs down, which meant the next UEF Storm was completely unanticipated and impossible to detect until it was over.
* Rachel invokes this to Marco in ''Literature/{{Animorphs}}'' once.
-->'''Rachel''': (looking toward the window) Is that a flying pig? Because that's the only way I would ever go out with you.
* At the beginning of ''Literature/TheJungleBook'' story "Toomai of the Elephants", the title character is told by Petersen Sahib that he may one day go into all elephant stockades "when thou hast seen the elephants dance" -- although there is evidence that such events occur, no human has yet witnessed it, thus the statement equates to "never". Sure enough, though, by the end of the story, [[CaptainObvious Little Toomai has seen the dance of the elephants]].
* There was a children's book by Valerie Coulman about this trope called-you guessed it!-"When Pigs Fly".
* In "Fire, Water, Air, and Pigs" a short story set in the land of [[Literature/TheQuestOfTheUnaligned Caederan]], a somewhat impetuous young wind-mage tries to fly a herd of oiled pigs from one side of the castle to the other to place them properly for a pig-catching contest. Even lampshaded:
-->'''Nahruahn (as narrator)''': We actually attracted quite a crowd the cook, several maids, the gardener and his two sons, and a number of fathers other servants. [[LampshadeHanging I dont think any of them had ever seen a flying herd of pigs before.]]
* In ''Literature/ADeepnessInTheSky'', it's mentioned that Qeng Ho genetic engineers routinely create flying pigs as a symbol as they go forth to do things sessile civilizations consider impossible. The geneticist at On/Off doesn't make any, because she finds flying kittens cuter. The mission produces miracles anyway, but judging from the sequel, nothing comes of them. Perhaps they needed the pigs.
* ''Literature/MagicShop'': In the fifth (published) story ''Juliet Dove, Queen of Love'', the title character is asked if she'll recite a poem at their town's annual Valentine's Day Poetry Jam, and responds with "When rats fly!" A few days later, the talking rats Roxanne and Jerome wake up with wings (ItMakesSenseInContext - they'd become temporary avatars of Cupid's power), and Juliet does indeed wind up reciting a poem at the Poetry Jam.

[[folder:Live Action TV]]
* In the fourth season of ''WhiteCollar,'' Neal is trying to find out [[spoiler: who killed Ellen]] by searching for the man she told him about, Sam. [[ConspiracyTheorist Mozzie]] suggests that Neal should ask for Peter's help, because Peter's FBI resources could be useful.
-->'''Neal:''' You realize somewhere pigs are flying right now?
-->'''Mozzie:''' Yes, and that ''is'' the sound of hell freezing over.
* ''SaturdayNightLive'': Around the time of the 2000 US presidential election, there was a "flash forward" skit in which each of the candidates (Bush, Gore, Nader) is giving a speech about the state of the nation under their yet-to-be administration. When it came time for Nader, he droned on for a while, and then stuffed winged pigs started floating past and a couple of earmuff -- wearing devils wandered into the shot rubbing their hands and throwing snowballs at each other.
* In one ''EverybodyHatesChris'' episode, Chris points out that his father's lack of an appetite can only mean one thing. Cue shot of Satan shivering and rubbing his arms.
* An episode of ''Weird, True And Freaky'' on animals with tattoos included a photo of a piglet with wings inked on its sides.
* In the ''{{Series/CSI}}'' episode "Appendicitement", the BBQ restaurant's kitschy decor includes a plastic pig statue with white feathery wings. The subplot set ''at'' the restaurant is, itself, rather tongue-in-cheek, with one implausible event after another.
* On ''MidsomerMurders'', Barnaby expresses his faith in the judicial process.
-->Look, we catch the criminals; we offer up the evidence. Not everyone likes what happens in court. Maybe the judge was right; give the boy one more chance. [[SarcasmMode Oh, look, a squadron of pigs over Causton]].
* On ''Series/FamilyMatters'' when Laura [[RelationshipUpgrade finally agrees to go out with Steve]], Steve throws his hands up and triumphantly declares "Hell has frozen over!"
* ''Series/ItsAlwaysSunnyInPhiladelphia'' recently had a ''spectacular'' example where Dennis boldly proclaims that if Charlie becomes King of the World, [[TemptingFate 'I'll blow myself']]. Cue episode title: [[spoiler: Charlie Rules the World.]]
* Lorne gets one of these in an ''Series/{{Angel}}'' episode.
-->'''Angel''': I'm buying
-->'''Lorne''': Ladies and gentlemen, hell just froze over.
* ''Series/KidsInTheHall'': If a line is so slow that its forward movement would only happen "when pigs fly", cue said Flying Pig to appear and entertain the crowds.

[[folder:Music]]
* When TheEagles got back together in 1994, they named the tour and the new album ''Hell Freezes Over'' (which was when Don Henley said they would get back together after breaking up 14 years prior, in 1980).
* Brad Paisley's "Come on Over Tonight" takes this attitude toward falling in love. "Come on over tonight, we'll sit on the swing / Watch the pigs fly by, flapping their brand new wings..."
* And, [[http://www.google.com/search?q=%22Chinese+Democracy%22+pigs+flying perhaps]], what was the best example on music: ''[[Music/GunsNRoses Chinese]] [[SavedFromDevelopmentHell Democracy]]''. Some even suggested [[http://img508.imageshack.us/img508/2747/chinesedemocracygt2.jpg this cover]].
* TomPetty, "It's Good to Be King":
-->Yeah I'll be king when dogs get wings
* The Foremen's ListSong of things that will never happen, ''[[http://www.royzimmerman.com/lyrics/best_froze.html Hell Froze Over Today]]''.
* PinkFloyd's ''Animals'' [[BookEnds opens and closes]] with "Pigs on the Wing." (and the album's cover has an inflatable pig, which was carried over to the band's live performances)
** And predictably, whe the band reunited for a one-off gig at Live 8 after ''decades'' of open conflict, several banners in the audience proclaimed "PIGS HAVE FLOWN."
* Music/TheMegas have the song "Hell Has Frozen Over," which features [[PlayingWithFire Fire Man]] and [[AnIcePerson Ice Man]] teaming up to take on VideoGame/MegaMan even though they had thought such a union could never be. Just to drive it home, the majority of the chorus is the words [[TitleDrop "Hell has frozen over"]] over and over again.
* Music/TheBeatles "Snookeroo" by Ringo Starr: "Oh, pigs will fly and the earth will fry, When they get me doing honest hours."

[[folder:Mythology And Religion]]
* [[OurGryphonsAreDifferent Hippogriffs]], believe it or not. They were originally a speculation as to what would result from obeying the expression "breed gryphons with horses." Since gryphons ''ate'' horses in the myths, the saying "breed gryphons with horses" meant to perform any impossible task. But hippogriffs eventually evolved from a joke creature into their own myth.

[[folder:Professional Wrestling]]
* Wrestling/StoneColdSteveAustin aligning himself with long-time ArchEnemy [[Wrestling/VinceMcMahon Vince [=McMahon=]]] at ''{{WrestleMania}} X-Seven''.
** Likewise, Wrestling/RicFlair aligning himself with long-time ArchEnemy Wrestling/HulkHogan after ''[[Wrestling/{{TNA}} Bound for Glory 10.10.10]]''.
* When Wrestling/BretHart appeared on ''[[Wrestling/{{WWERaw}} Raw]]'' in 2010, 12+ years after the {{Kayfabe}} Wrestling/MontrealScrewjob he said that he guessed hell just froze over.
* At ''TLC 2011'', Wrestling/CMPunk, Wrestling/ZackRyder, and [[Wrestling/BryanDanielson Daniel Bryan]] walk out as the WWE Champion, US Champion, and World Heavyweight Champion respectively. Punk and Bryan are Indies wrestlers, which have great difficulty in the WWE and them alone would be enough. Zack Ryder? He was a ''jobber'' who worked his way up to this point through sure, home grown PopularityPower he got purely by himself! This is probably the single biggest Cue The Flying Pigs moment in ''WWE history!'' CM Punk, being who he is, [[LampshadeHanging lampshades this]] to no end the next night.
* Speaking of CM Punk, this was the general reaction when Punk made Vince apologize to him. [[HolyShitQuotient On live television]].
* Wrestling/{{Christian}}, the newly crowned WWE Intercontinental champion, turning up at TNA's ''Slammiversary'' Pay Per View to present the number one moment in TNA history, as voted by the fans.
* While he remained involved in professional wrestling on some level or another over the years even after retiring, if one only watched WWE, you'd get the impression Wrestling/BrunoSammartino had nothing to do with the sport whatsoever due to a long-standing hatred of Vince [=McMahon=]. So him going to the WWE Hall Of Fame in 2013 was this to many, be they WWE fans who thought he fell off the grid or fans of other promotions who insisted Bruno had no incentive to take WWE's offer, already being in ''their'' halls of fame.
* Wrestling/BarryHorowitz teaming in Wrestling/AllJapanProWrestling with ''[[Wrestling/StanHansen STAN HANSEN]]'' qualifies, not so much because of any feud between the two, but because of how Hansen is one of the biggest foreign stars in the history of Japanese wrestling and Barry is best known, unfortunately, for his long losing streak.
* The fans at ''WrestleMania XXX'' looked like the ring had just exploded when Wrestling/BrockLesnar '''''[[DefeatingTheUndefeatable ended]] [[Wrestling/TheUndertaker The Streak]]'''''. '''''[[HolyShitQuotient Cleanly]]'''''.
* Wrestling/ReyMysterio winning the Royal Rumble 2006 for a number of reasons: 1) he's billed at 5'6, pretty much the smallest wrestler on the WWE roster at the time, 2) this is just months after Wrestling/EddieGuerrero's passing and this match was in his memory, and 3) he's the #2 entrant, Wrestling/TripleH being #1. He won through it all, and still holds the record at longest Royal Rumble time at ''62 minutes''.
* And two years prior, Wrestling/ChrisBenoit lasting 61 minutes, 30 seconds by eliminating Wrestling/TheBigShow by ''pulling the giant'' from under the bottom rope.
* Wrestling/AJStyles leaving Wrestling/{{TNA}} was legitimately shocking due to his reputation as a company man and having been there (literally) since the very beginning, making him one of the TNA Originals. That was enough for many fans to start declaring that TNA is dead.
* In 2001, a wrestler with Wrestling/WorldChampionshipWrestling stated that he didn't want to work with Wrestling/VinceMcMahon (and for a good reason considering what he did with some other WCW talent...). 13 Years later at Survivor Series, Wrestling/{{Sting}} debuted.
* Everybody thought that CM Punk wouldn't go into detail about what happened when he left WWE back in January. Then the 27th of November happened, and [[Main/NiceJobBreakingItHero the internet exploded]].
* The Wrestling/{{WWE NXT}} developmental brand's final two-hour special event of 2014, Takeover 3: R-Evolution, received such rave reviews, especially compared to the main roster TLC pay-per-view/Network special which would take place that same week, that the "NXT is superior to the main roster" sentiment which had been building for a long time finally exploded. This, combined with the WWE Network's financial woes and controversial comments from Wrestling/VinceMcMahon which fans have perceived as proving true the complaint that Vince is out of touch with today's wrestling audience, has a noticeable contingent of wrestling fans, WWE wrestlers, and even investors with the company saying Vince should step down. The flying pigs part? ''Wrestling/TripleH, Wrestling/TheKliq member who married Vince's daughter Wrestling/{{Stephanie|McMahon}}, the man notorious for protecting his spot at the expense of other wrestlers when he was an active performer, has been the man in charge of NXT since it became the developmental brand. And they want '''HIM''' to take over.''

Oh, and the [[EldritchAbomination Shambling Corporate Presence]] is finally making progress at work.
* ''VideoGame/DukeNukemForever'': Several years ago, 3D Realms employee George Broussard said that ''Duke Nukem Forver'' would be released "when pigs fly." On September 1, 2010, however, his Twitter account linked to [[http://bp0.blogger.com/_awSNbDFeIPs/RjHkcL5Z9hI/AAAAAAAAACk/vw4PGZo9Jxs/s1600-h/pigs-fly.jpg this picture]], and a playable demo of ''Duke Nukem Forever'' was on display at Penny Arcade Expo.

* A conversation in ''VideoGame/VagrantStory'' has a soldier claiming that swine will take wing before soldiers dabble in black magic, and his friend retorting that with a Grimoire's power, a sow could outfly a falcon. It later turns out that the Cardinal, as well several soldiers under his employ, are proficient in the Dark Arts.
* ''[[VideoGame/DonkeyKongCountry Donkey Kong Land]]'' [[InvokedTrope invokes this trope]] with the [[{{Feelies}} Guidebook]] talking about how people shouldn't invoke the flying pigs, and then introduces a [[LiteralMinded Flying Pig enemy]] [[TakeThatUs Hogwash]].
* In the heaven-and-hell sim ''VideoGame/{{Afterlife}}'', one of the disasters than can strike is Hell Freezes Over. The description reads "Once in a long while, little pieces of Hell freeze over. No one’s sure why this happens, but many Demons attribute the phenomena to [[TakeThat honest politicians, surprisingly strong dramatic performances by Madonna, and the occasional Rose Bowl appearances of Stanford and Northwestern]]."
* Early in ''Companions of Xanth'', after an InfoDump about Literature/{{Xanth}} and magic, still skeptic Doug sarcastically remarks that he just saw a pig fly. Nada replies that [[ComicallyMissingThePoint the migration season hasn't started yet]], and he must be mistaken.

* In ''Webcomic/TheOrderOfTheStick'' book ''Snip, Snails, and Dragon Tails'', 4e Haley explains to 4e Elan, that she used her Knockout on 3e Durkon by stabbing him in the foot. She had "used the power of abandoned verisimiltude" -- and she and Elan are surrounded by flying pigs.
* In ''Webcomic/SchlockMercenary'', after [[LivingShip Tagii]] is locked down and Tagon has Ennesby take control of the ship, he comments on the irony of what he said the last time Ennesby asked to be the shipmind.
-->'''Tagon:''' I guess I was wrong. If you're the last {{AI}} on the planet, I ''will'' let you fly my ship.
* In the ''WebComic/AndShineHeavenNow'' arc "Fangirls Are Hell" we see hell freeze over, and all the other fangirls and fanboys literally frozen in shock because what they thought was impossible happened: [[CanonForeigner Incognito]] has ''fans''.

* As seen in the page quote. This was invoked by WebVideo/TheNostalgiaCritic for his review of the ''WesternAnimation/TomAndJerry'' movie, when he found out that [[TheVoiceless Tom and Jerry]] ''talked'' in it.
* A Beanie Baby-themed HarlemShake video actually has a flying pig.

* ''WesternAnimation/RobotChicken'':
** We see hell freeze over ''before'' it cuts to a half naked nerd dance around singing "I got laid! I got laid!" with a hot girl in the background saying that she thinks NerdsAreSexy.
** A small girl asks her mother if her curfew can be midnight. Her mother replies "only when pigs fly". The daughter then launches her pet pig out of a catapult to get her mother to change her curfew.
* ''WesternAnimation/SheepInTheBigCity'': There's a crazy example in the first season finale, where the narrator is being carried away to fuel the narrator-powered ray gun, he begs to himself that it's all just a dream, then the flying pig appears and says it's real, or else he won't have wings. Cue BigNo.
* In ''WesternAnimation/TheSimpsons'' episode "Lisa the Vegetarian", after an actual roast pig is already flying through the air [[ItMakesSenseInContext for perfectly good reasons]], we randomly cut to a completely unrelated scene where Burns is telling Smithers that he'll donate an enormous amount of money to charity when pigs fly, and they both have a good laugh...which fades as they look out the window.
-->'''Smithers:''' Will you be donating that million dollars now, sir?
-->'''Burns:''' Nnnno, I'd still prefer not.
** [[SubvertedTrope Subverted]] in the episode ''Monty Can't Buy Me Love'', where Mr. Burns and Smithers enter a book store:
--> '''Burns:''' Books and cocoa in the same store? What's next, a talking banana?
--> A moment of [[IncrediblyLamePun fruitless]] waiting follows.
-->'''Smithers:''' Uh, I don't see one, sir.
-->'''Burns:''' Of course not. The very notion of a talking banana is absurd. But still....
** In the 2014 ''TreehouseOfHorror'' episode Lisa is in a school in Hell and joins a group of "popular" demon girls, then it starts snowing. "Wow, it was a cold day in Hell that I become popular."
* ''WesternAnimation/JackieChanAdventures'' "Billy Joe, I will marry you when pigs fly!" Cue flying pig shooting [[EyeBeams heat-beam eye-blasts]] (though the flight part was caused by the rooster accompanying the pig.)
* In one episode of the ''WesternAnimation/AladdinTheSeries'', the rarity of two genies falling in love is illustrated by the presence of [[UpToEleven flying pigs playing croquet in the skies above Agrabah]].
* Played with in the ''WesternAnimation/LooneyTunes'' short "Crowing Pains", where Foghorn Leghorn gets halfway through the phrase "I hope to be struck by lightning" when an ominous rumble of thunder and a lightning bolt appearing behind him forces him to reconsider.
** Another short, "Fool Coverage," ends with one big parade of the trope. Daffy is trying to convince Porky to buy insurance. In the process, Daffy runs into mishap after mishap, and this convinces Porky to sign. He then says all he needs to get a million dollars is to get a black eye. Daffy then notes that the policy [[ImpossibleInsurance has a list of impossible conditions]] (no pigs, but there is a stampede of wild elephants). Cue Daffy's chagrin when ''every single one'' of the conditions occur...''including'' the one he made up on the spot (one baby zebra).
* This happens several times in ''WesternAnimation/AlmostNakedAnimals'', considering one of the characters is a pig...
--> '''Octo''' "Aren't bad things meant to happen when pigs fly?"(cue comic slapstick)
* ''WesternAnimation/SpongeBobSquarePants'', Played with in "Spongeguard on Duty":
-->I'm every bit as cool as Larry, and if I'm not, let me be struck by... (thunder) ...a flying ice-cream truck. (ShadowOfImpendingDoom, accompanied by BombWhistle and ice-cream truck chimes) ''AND LIVE!''
* ''WesternAnimation/SouthPark'': [[SubvertedTrope Subverted]] when Cartman is not hit by lightning when he says he has never done anything just for the money, although Butters does moves out of the way.
** Kyle's parents will only allow him to go to a concert when he cleans out the garage, shovels the driveway, and brings democracy to Cuba. His parents explain that he wasn't actually supposed to accomplish the last one but he expressed more concern about shoveling the whole driveway.
* ''WesternAnimation/TheBoondocks'': Huey, after a number of odd schemes, fails to prevent the execution of an obviously innocent man on death row. Uncle Rukus, struck by lighting in the beginning of the episode, claims to have spoken to God and creates an televangelical craze by claiming that hatred of black people, including self-hatred, can get one to heaven. As Rukus makes the standard 'may i be struck by the Lord himself' a lighting bolt strikes the microphone in his hand. The electrical blast causes a blackout moments before the electric chair for the execution is activated. This is followed by the Governor finally calling to stay the execution.
* When ''WesternAnimation/FamilyGuy'' was {{Uncanceled}}, their very first scene back was Peter breaking the news to the family that their show had been axed by Fox. When asked why, he explains that Fox needs to make room for their hot new shows such as ''{{Series/Firefly}}'', ''DarkAngel'', and about [[ScrewedByTheNetwork three dozen other programs]] which had come and gone in the period that ''WesternAnimation/FamilyGuy'' was on hiatus. When Lois asks if there's any hope, Peter replies sarcastically that they might have a shot if all those other shows get dropped. Roll opening credits.
* A running gag in the first season of ''WesternAnimation/AmericanDad'' has Hayley telling Stan that he can do some crazy thing 'when pigs fly'. He then calls a CIA lab and tells them to keep working on the flying pig experiment.
** In one episode, Stan called the CIA and they told him that it's almost complete and it shows a pig with only one wing.
* ''WesternAnimation/MickeyDonaldGoofyTheThreeMusketeers'' had DonaldDuck muttering "I'll be a musketeer when cows fall out of the sky!" Naturally, Clarabelle the Cow happens to be falling from the bridge above at that moment.
* On ''WesternAnimation/JohnnyBravo'', when Susie says Farrah Fawcet is her cousin, Johnny notes "Yeah, and pigs fly." Then he looks up in the sky...
* On ''WesternAnimation/JimmyTwoShoes'', when [[{{Satan}} Lucius]] tells the story of how he won his bowling trophy, it involves him telling his father if he makes the strike, [[HumanPopsicle he gets to freeze him]]. Lucius VI agrees, muttering "And pigs will fly." Of course, Lucius makes it. Flash forward to the present where he's frozen, and his son is holding a flying pig on a leash, saying "He was always making crazy bets."
* Possible reference to this trope in ''WesternAnimation/AvatarTheLastAirbender''. Toph's family crest is the Flying Boar, which is, well, a boar with wings. A vision of such a creature is part of what leads Aang to her, and it may be a reference to how unlikely it would seem for a 12-year-old blind girl to be such a master bender.
** More specifically, said minute, 12 years old blind girl is a master Earthbender.[[DontExplaintheJoke The majority of Earthbenders are burly men.]]
* On ''WesternAnimation/TheFairlyOddparents'', when Timmy beats Vicky to determine the new [[ItMakesSenseInContext Queen]] of the Skatepark, she [[ILied refuses to step down]], claiming that he's got a better chance of some loser 12-year-old plummeting from the sky and plowing her into the ground than her [[GracefulLoser gracefully accepting her loss]]. [[BrickJoke Francis immediately falls from space right on top of her]], and she [[CrowningMomentOfFunny cheerfully hands over her crown]].
* In ''WesternAnimation/YinYangYo'', Yang tells Yin that she'll only get a boyfriend when pigs fly. Later, when Yin actually gets a boyfriend, a nearby pig suddenly sprouts wings and flies off, spotted by Yang.
* ''WesternAnimation/MagicAdventuresOfMumfie'' has a flying pig named Pinkey in it. And yes, the characters do have a lot of good luck in this series.
* ''WesternAnimation/StarVsTheForcesOfEvil'': In "Brittney's Party", [[AlphaBitch Brittney Wong]] says that she'll invite Star to her birthday party when pigs fly, so Star magically conjured up a flying pig.
-->'''Star:''' Problem solved.
-->'''Pig:''' Anything for you, Star. ''(Brittney swats at him)'' Flyin' pig don't need this.

[[folder:Real Life]]
* One overly complicated joke that can be found on the Internet has a graduate student answering the question of whether Hell was exothermic (releasing warmth) or endothermic (absorbing it) on his final exam, via the postulate a cheerleader had told him his freshman year, that she'd sleep with him when Hell froze over. Since he'd slept with her last week, this proved that not only did Hell exist, but it had frozen over and thus it was endothermic. There's an alternate version where, because the person ''hadn't'' slept with him, that proved that Hell was exothermic. Despite the claims that it was a real answer in a real university exam, it's not.
** The gist of the joke though is that he makes several otherwise scientific postulates, such that a soul has a certain amount of energy, and since every religion says that if you don't believe in that religion you're going to hell i.e. everyone is going to hell, the question becomes whether hell is expanding faster than there are souls going into it (hell freezes over) or it is expanding slower than the rate of souls going into it (all hell breaks loose). Then he discards those for the punch line.
* A spoof news story from 2002: "Pigs flew over the frozen landscape of Hell yesterday as amazon.com reported its first ever profit."
* Before Eurovision Song Contest 2006, after a Finnish metal band was announced, it was said that "Hell will freeze over before Finland wins". Finland got 292 points, at that time the highest number on record.
** Perhaps ironically, the Finnish band was Lordi, which was almost not admitted due to accusations of Satanism. Definitely ironically, the song with which they won was "Hard Rock Hallelujah," which the band's "face", Mr. Lordi, [[TheDevilIsALoser used as proof that they're not Satanic.]]
** According to a pre-2006 Russian joke: ‘At -10 degrees Celsius, heating is switched on in British homes, while Finns change into a long-sleeved shirt. At -20, Austrians fly to Málaga, while Finns celebrate midsummer. At -200, hell freezes over and Finland wins the Eurovision Song Contest. At -273 absolute zero temperature is reached, all atom movement ceases. The Finns shrug and say: “Perkele, a bit chilly today, isn't it?”’
* Appropriate headlines were done when Apple switched to Intel processors.
* James Randi presents Pigasus Awards (Pig + Pegasus) each year for paranormal fraud in several categories.
* HunterSThompson and the Battle of Aspen. Thompson ran for Sheriff of Pitkin County, Colorado, of which Aspen is the county seat. Folks said that the long-haired hippie-types who formed the "Freak Power" movement to elect Thompson would win when pigs flew, or some such. Thompson shaved his (already [[BaldOfAwesome balding]]) head, and began referring to the crew-cut Republican candidate as "my long-haired opponent."
* The New Orleans Saints for the most part were one of the worst NFL teams; some exclaiming that "Pigs Would Fly" if the Saints went to the SuperBowl. Recently though, the Saints' fortunes have changed for the better and in 2010, the Saints finally got the right to play in the Super Bowl, which Saints announcer Jim Henderson then exclaimed: ''"Pigs have flown! Hell has frozen over! The Saints are on their way to the Super Bowl!"'' ItGetsBetter...making sure that "Pigs Were Flying" in UsefulNotes/NewOrleans, the Saints would go on to win the Super Bowl.
** A popular radio sportscaster in New Orleans once said that if the Saints ever made it to the Super Bowl he would wear a dress. He died before he got the opportunity, so former Saints quarterback Bobby Hebert led a drag parade in memory of this trope. It managed to be [[CrowningMomentOfAwesome all]] [[CrowningMomentOfFunny three]] [[CrowningMomentOfHeartwarming types]] of Crowning Moment at once.
* [[http://www.airbridgecargo.com/press/news/798.html 1,275 breeding pigs flown to Vladivostok.]]
* An Italian soccer team has embraced a variation of this trope, but with donkeys instead of pigs. Verona hosts two soccer teams: Hellas Verona and Chievo Verona. In the past decades, the first team used to play in Serie A, while the second used to play in Serie B. Supporters of Hellas Verona even made a rhyme about this: ''Quando i mussi i volerà / faremo il derby in serie A / e sarà sempre così / Verona in A e Chievo in B''. Translated into English: ''When donkeys fly / we'll have a derby in Serie A / and it will always be like this / Verona in A and Chievo in B''. Cue 2001, when Chievo was promoted to Serie A and went on to actually play two derbies against Verona. At this point, Chievo itself embraced the trope, inserting the picture of a flying donkey in the team's website and getting the nickname "i mussi che vola" (="the flying donkeys"). For added irony, Helllas Verona were stuck in the bottom of the third division in 2007-08 (although Chievo spent their only season outside the top flight since 2002 then- they won Serie B easily, and have remained in Serie A since 2008, in spite of a terrible start to the 2008-09 season), but survived due to the financial predicaments of others, and, in 2011, managed two promotions in 3 years to return to Serie A and take on Chievo again.
* As almost everyone knows by now, there is a town in Michigan called Hell. Being in Michigan, it has been known to freeze from time to time. There's one in Norway as well.\\
\\
The one in Michigan has begun to realize this, and has begun to [[http://www.flickr.com/photos/stormdog42/sets/72157624704514053/with/4935976169/ market themselves]] (sigh) to Hell and back. When Caroline Rhea had her own talk show, she asked one of the town citizens if she had seen her ex-boyfriend (whom she had told to go to hell previously.) The woman said that he had enrolled in their local university, Damn U. They also sell souvenirs (Hell in a Hand Basket) and toys (Bat out of Hell) and even have an Ice Cream Parlor.
* There's an [[http://www.snopes.com/quotes/mrgorsky.asp urban legend]] that when Neil Armstrong was a boy, he overheard his next door neighbors arguing loudly. The wife shouted at her husband, "I'll give you oral sex when the kid next door walks on the moon!"
** I wonder what she was doing when that actually happened?
** Johnny Carson told America in his monolog that NBC had given him a raise. "It was in my contract that I'd get a raise when people walked on the moon."
** Similarly, legend has it during one batting practice early in his career someone remarked that "they'll put a man on the moon before" then-San Francisco Giants pitcher [[http://en.wikipedia.org/wiki/Gaylord_Perry Gaylord Perry]] hits a homer (major league pitchers aren't usually known for their batting prowess). The most often-cited source of the quote is Alvin Dark, who managed the Giants from 1961-1964. It's not known for sure if Dark or anyone else actually made this claim, but Perry did hit his first career homer about twenty minutes after the P.A. at Candlestick Park announced that the ''Eagle'' had landed on the moon.
* In AustralianRulesFootball, the Sydney Swans had a long losing streak in 1992-3, which ended when they beat the Melbourne Demons. The next day, a newspaper cartoon featured two demons standing in a frozen-over hell, with one saying, "Looks like the Swans finally won a game."
* During UsefulNotes/WorldWarII, UsefulNotes/{{Brazil}} was in a bit of a bind--traditionally aligned with the Allies and heavily dependent on American trade, the regime at the time was authoritarian with Fascist sympathies, and as a result tried to remain neutral. As a result, the dictator Vargas said that Brazil would enter the war "when snakes smoke" (at the time a Brazilian Portuguese expression for "when pigs fly"). When Brazil actually did join the war in 1943, the [[http://en.wikipedia.org/wiki/Brazilian_Expeditionary_Force Brazilian Expeditionary Force]] was nicknamed the ''Cobras Fumantes''--the "Smoking Snakes". Their insignia was even [[http://en.wikipedia.org/wiki/File:Distintivo_da_FEB.PNG a snake smoking a pipe]]. Ever since , "''a cobra vai fumar!''" ("snakes will smoke!") has meant "it will definitely happen, and it will be ''huge''!" in Brazilian Portuguese.
* Also during World War 2, Hermann Goering supposedly said, "No bomb will fall on Berlin (or, in some versions, the Ruhr). If they do, you can call me Meyer." German population called air raid sirens, common over most of Germany in the latter half of the war, [[http://www.historynet.com/why-did-goering-say-you-can-call-me-meyer.htm "Meyer's trumpets"]] on the account of this.
* A recent joke: In the 1970's, people said America would have a black president when pigs fly. In 2008, they elected Barack Obama, and sure enough, [[JustForPun swine flu]].
* It is said that before he became Emperor, [[TheCaligula Caligula]] met with a fortune-teller, who told him 'you are as likely to rule the Roman Empire as you are to ride across the bay of Naples without getting your horse wet.' When he did become emperor, he commandeered all the boats in Naples, lined them up from one side of the bay to the other, and rode his horse across them, just to spite the fortune teller.
