->'''Buffy:''' I told one lie. I had one drink.\\
'''Giles:''' Yes, and you were very nearly devoured by a giant demon snake. The words "Let that be a lesson" are a tad redundant at this juncture.
-->-- ''Series/BuffyTheVampireSlayer'', "Reptile Boy"

The author has an important [[AnAesop Aesop]] for the audience. There's an urgent course of action they want you to take, and they've decided to show you the tragic consequences of ''not'' doing so.

Trouble is, the real consequences, while they may be serious, aren't the sort that can easily be made to fit the RuleOfPerception. Maybe they take decades to show up, if they show up at all. Maybe they happen so subtly that it's hard to show ''why'' the action should be taken.

Worse, maybe there isn't yet agreement on what the real consequences are. How can we be ''sure'' what will happen to the Earth [[Film/StarTrekIVTheVoyageHome if we drive all the humpback whales extinct?]]

So the author dreams up some improbable, highly unforeseeable consequence to scare you into complying.

When done right, the improbable consequence will be a close analogy or a sharp metaphor to the probable one--just increased in scale, speed, or concreteness. You know irreparable damage will be done to the earth's ecosystem if the whales go extinct, but not ''what'' irreparable damage; and so, you arrange it so that the absence of whales leads to aliens endangering all life on Earth--''especially'' the humans.

When done wrong, it'll defy all logic. Often, how well it comes off depends on how close you're looking and (if the consequences are still unknown) what you believe.

Named for (and derived from) the plot of Star Trek IV, which can best be summed up as "'''Don't let whales go extinct, or else an alien probe will eradicate the planet.'''"

This trope should not be confused with FantasticAesop. The Fantastic Aesop promotes or discourages a course of action which can't even be ''attempted'' in the real world (e.g. "Never use black magic to resurrect the dead") by showing a reasonably plausible set of consequences ("Poor beloved Tropey CameBackWrong".) The Space Whale Aesop promotes or discourages a course of action which ''can'' be attempted in RealLife ("don't perform nuclear tests") by showing ''consequences'' that strain credibility ("radiation from the tests will awaken [[Franchise/{{Godzilla}} a giant monster]] that destroys Tokyo") instead of a more realistic but not quite as dramatic example ([[http://www.youtube.com/watch?v=lmvbjcmyKGo "it can burn whole buildings if someone is careless"]]).

Overlaps with GaiasVengeance if the intended message is an [[GreenAesop environmental one]], which it often is. Overlaps with SpoofAesop when the author is more interested in the space whale than the Aesop. Overlaps with AbusiveAdvertising if the message is "Buy our product or you'll meet with a grisly end somehow."

[[TropesAreNotBad This is not necessarily an indefensible trope.]] If your purpose is to both teach the audience a highly applicable lesson ''and'' to entertain them with a fantastic scenario, then a Space Whale Aesop is probably the best way to go. And speaking about entertainment, RuleOfFunny may also be a huge factor in some more complicated cases. Also, sometimes you just can't fit the realistic consequences of an action into a twenty-three-minute episode or a 120-minute film, so you need to speed things up a bit.

Before posting anything think for a second: "Is this supposed to be an Aesop?" If it was ''not'' intended as an Aesop then that is an AccidentalAesop.



* [[http://www.youtube.com/watch?v=P9-kblZwfv0 "No Pressure"]]: Agree to cut carbon emissions, or someone will press a button and [-BLOW YOU TO BLOODY BITS!-] So {{Anvilicious}} it's ridiculous. Many of the Website/YouTube commenters (amongst other people) have taken the message to be "do as we say or we'll murder you".

* [[Advertising/GetRidOfCable A series of DirecTV Network advertisements]] intentionally invokes this trope for comedy with such aesops as:
** "Switch to [=DirecTV=] or you'll get angry, go play raquetball, get your eye injured and get an eyepatch which thugs will use as a reason to beat you up, knock you unconscious and leave you in a ditch." So remember kids, go satellite for your safety!
** "If you have cable, you'll pound your table in frustration with how terrible it is, which will cause your daughter to copy that behavior and punch the lunch out of her principal's hands when she gets older, which will get her expelled, which will cause her to hang out with street toughs, which will cause her to marry a street tough. 'Don't have a grandson with a dog collar.'"
** If you have cable, you'll throw your remote in frustration, which will just barely miss your wife's head, which will make her assume you have anger issues, which will make her leave you, which will leave you all alone, which will make you grow a beard and become an animal hoarder.
** If you have cable, you'll get depressed, go to self-help seminars, get motivated enough to go to Vegas, where you lose everything and are forced to sell your hair.
** If you have cable, you'll get unhappy, go to Happy Hour, get happy enough to try a Turkish Bath House, where you'll meet Creator/CharlieSheen and start re-enacting scenes from ''Film/{{Platoon}}''.
** As a defense attorney, if you don't have [=DirecTV=], you'll be distracted, which means your work will suffer, which will cause your innocent client to get convicted, which will cause him to become obsessed with your failure to get him cleared, which will cause him to blow up your house when he gets out.
** If you have cable, the massive price of the bill will make you feel powerless. So you'll want to feel empowered, which will lead you to signing up for karate classes, which will lead you to become a superhero known as the "Fist of Goodness" which will have you jumping on rooftops. And when you jump on rooftops, you'll crash through a skylight into a dinner party.
** If you wait a while for the cable guy, you'll become bored, look out your window and see things you shouldn't see (the disposal of a body, in this case), so you'll need to vanish, fake your death, dye your eyebrows and [[AttendingYourOwnFuneral attend your own funeral]] as a guy named Phil Schiffly.
** If you pay too much for cable, you'll get depressed, stay at home a lot, and lose your job. The new guy will mess up at doing your job (Zoo worker), accidentally let a gorilla escape, and said gorilla will body slam you while you pick up the paper the next morning.
** Basically, an entire ad campaign based on this trope combined with ForWantOfANail.

[[folder:Anime and Manga]]
* The underlying lesson of ''Anime/PrettyCure'' seems to be "it's good to have friends who are different from you, so you can defeat monsters from another dimension." It gets spelled out in [[Anime/PrettyCureAllStars the first DX movie]], in which the girls are fighting a monster with an AssimilationPlot on its mind and give a rousing speech about how their differences make them stronger because everyone brings something different to the table.
* The final arc of ''Anime/EarthMaidenArjuna'' features a {{Broken|Aesop}} {{Green|Aesop}} Space Whale Aesop. "Save the environment, but don't use advanced human science to save the environment from human-produced garbage, or else giant worm monsters will exploit your invention to send corrupt modern society back to the Stone Ages." If you look more closely, though, you see something different. Using human science isn't the problem. The heroes ''use'' human science to aid in their efforts and it works great. The issue is that humans weren't attentive enough and so things have now got to a point ''where human science is not enough'' and the earth basically has to go through a cycle of destroy and repair (there's a very strong analogy to the inflammatory response in humans). So really the aesop is "If you don't save the environment while you can, the earth will revolt and take over repairing itself, while humans will be powerless to do anything except watch."
* ''Manga/AttackOnTitan'': Racism is bad! Because people of minority races are [[spoiler:immune to the GovernmentConspiracy's magic memory wiping that they use to cover up where the man-eating giants are coming from! It's possible this was meant to show how some often-persecuted minorities are more aware of when governments are being oppressive]].
* ''{{Manga/xxxHOLiC}}'' pretty much runs on these kinds of aesops since it assumes AllMythsAreTrue: don't lie or you'll get so paralyzed by them that you'll be run over by a car, don't cut your toenails at night or a giant insect will chop your head off, don't kill someone or your act of murder will be reenacted on every photograph and video that has you in it…etc.
* An episode of the {{hentai}} ''Sex Craft'' demonstrates that you shouldn't break up with the guy you're dating just because he's too shy to make the first move, because... if you do that, his unquenched desire will escape his body in the form of an evil ghost thing and go on a rape spree.
* ''Manga/SquidGirl'' teaches us [[GreenAesop not to pollute the ocean]] or a cute, harmless Squid Girl will come to the surface and try to invade it! [[BrokenAesop Wait, that's every reason to actually do it...]]
* Anvilicious "revenge is wrong" moral in ''Anime/{{Naruto}}'' reaches this territory by the end of Pain invasion arc, when Naruto confronts [[spoiler: Nagato]] after the battle. His crimes so far include [[spoiler: killing Jiraiya and Kakashi as well as many Konoha ninjas, almost killing Hinata and turning entire Konoha into rubble]]. Naruto himself admits that he would love to kill him but refuses to. After some pep talk [[spoiler: Nagato performs a HeelFaceTurn and uses SacrificialRevivalSpell to bring all dead people in the village back to life]]. Lesson ends up being:[[spoiler: "If you refuse to kill the bad guy all his crimes will be cancelled, and bad guy will die anyway "]].
* [[SpoofAesop Parodied]] in an episode of ''Anime/CowboyBebop''. [[spoiler:"Clean out your fridge or its contents will become sentient and start attacking people."]]
* ''Manga/TriGun'': Don't practise slavery, otherwise [[spoiler: a {{Human Alien|s}} [[ANaziByAnyOtherName Ubermensch]] will slaughter half of your species with his giant knife arms]].
* ''Anime/ParanoiaAgent'': Take responsibility for your own actions and don't lie, or you'll [[spoiler:conjure a {{tulpa}} with your PsychicPowers and almost destroy your city]].
* ''Manga/{{Batman}}'', from its story "The Revenge of Professor Gorilla": don't abuse apes in circuses and in scientific research, because then when your mad science accidentally gives them superhuman intelligence and psychic powers they'll try to exterminate humanity.

[[folder:Comic Books]]
* ''ComicBook/ChickTracts'' do this by giving his transgressions explicitly magical consequences, since the real consequences of the behavior he warns against are both intangible and ''heavily'' disputed. For instance, "don't let your kids play ''TabletopGame/DungeonsAndDragons'', or they might become actual witches, or commit suicide because their character died" is probably the most famous example (who knows what he thinks of ''VideoGame/WorldOfWarcraft''). Another strip seems to suggest that you shouldn't go to parties because the bartender might actually be Satan, and yet another that believing in Santa and the Easter Bunny will turn children into God-hating, terrorist serial killers. Chick's been keeping pace with the times: more recently, his tracts suggest that reading ''Literature/HarryPotter'' will make you into a full-fledged Satan worshiper with demon-summoning powers. And worse, the author seems to honestly believe these are all perfectly realistic consequences.
* There was a ''Franchise/{{Wolverine}}'' arc which involved a South American country with a ruler who suffered acute superhero envy backed up by an ex-Nazi cyborg. Either of them sound like an awesome main villain? The final villain was ''evil crack from the dawn of time'' which drove its victims insane and, at one point, absorbed Wolvie into its horrifically bloated gooey true form. The message was DrugsAreBad. It even gave us ''ComicBook/TheKingpin'' [[EvenEvilHasStandards expressing distaste for drug dealing]], making it not just a Space Whale Aesop, but an ''{{Anvilicious}}'' Space Whale Aesop.
* The ''WesternAnimation/{{Gargoyles}}'' comic plays this for laughs when a time-traveling Brooklyn breaks the fourth wall to teach a lesson to the audience:
-->'''Mary:''' Don't you know what is going to happen?\\
'''Brooklyn:''' Too much TV, too few history books. (points at the reader) You never know when a giant flaming magical time-traveling bird is gonna swallow you whole and spit you out in the tenth century. So hit those books, kids!
* ''ComicBook/JohnnyTheHomicidalManiac'' does this for laughs.
-->'''Johnny:''' Kids, don't do drugs. They'll only turn you into a hideous little freak troll-baby with exploding eyeballs.
* ''Comicbook/UncannyAvengers'' gives us "Don't be racist or else giant men from space will appear and blow up the Earth." Odin even gives [[Comicbook/TheMightyThor his son]] an extended speech about how while the Celestials pulled the trigger, it was ultimately humanity's own inability to stop fighting over petty differences that caused them to deem us a "failed experiment." Though there were a few extenuating circumstances, such as one of those giant men having been murdered by a human mutant was what kicked off the crisis.
* The [[Creator/ECComics E.C. horror comics]] frequently used this trope, to demonstrate the consequences of many immoral acts, ranging from "Don't screw your business partners" (or when you try to escape to South America, your plane will become trapped in the web of a GiantSpider), to "Don't cheat on your wife" (because when she and your mistress find out about each other, they may decapitate you and use your head for a bowling ball and your eyeballs for golf balls), to "Don't murder your spouse" (he or she will come back from the dead some time later and murder you back).
* ''ComicBook/{{Grimm}}'' dipped into this trope frequently, due to its method of having the main character try to teach someone an "important lesson" via reading a fairy tale. One of the biggest examples being the Rumpelstiltskin, when an unwed teenage mother-to-be is taught to not get an abortion (a fairly controversial Aesop to begin with) via a story about a woman who gets threatened with death unless she can spin straw into gold and is forced to promise her firstborn to the title dwarf unless she can guess his name. Only it's a trick, and by saying his name in an attempt to save her baby, she instead releases Rumpelstiltskin from his curse (which is then passed on to her baby). And the lesson to all this is apparently that if you're ever in a position where you're forced to choose between giving up your firstborn baby to a stranger or die, you're actually screwed either way.
* ''ComicBook/TwoThousandAD'': Played for laughs in ''ComicBook/ThargsTerrorTales'' stories. Smoking weed will turn you and your friends into zombies, being a horndog will make StarfishAliens rape you to death, going to a rock concert will result in monster cops cracking down on everyone, etc.
* {{Franchise/Superman}}'s foe Titano's post-crisis origin says that animal testing is wrong because it causes the animal unnecessary pain and makes them grow gigantic and wreck the city.
* Perhaps {{lampshad|eHanging}}ing the trope, ''[[Recap/MyLittlePonyFriendsForeverIssue28 My Little Pony: Friends Forever #28]]'' features a unicorn whose magic talent is a seemingly useless spell that turns flesh and muscle invisible (though leaving their skeletons visible). The talent proves itself useful, and provides the issue's Aesop, when the main characters encounter a flying "Mirrorca", an orca with a mirror-like skin, that can only be defeated by turning its skin invisible and making it vulnerable to magic attacks.
* ''[[SelfDemonstrating/{{Lobo}} Lobo: I Quit]]'' is another deliberate example played as comedy. Shortly after Jonas Glim lectures Lobo on the dangers of his constant smoking, Lobo gains a wheezing cough and a shadow on his chest X-ray, suggesting not even his healing factor can keep up with the damage he's doing. At the end of the issue, Lobo has completely cured himself of his habit, a fed-up Jonas slugs him in the stomach for accidentally punching him--and Lobo coughs up [[MakesJustAsMuchSenseInContext the harmonica he swallowed in an earlier fight with a street gang dressed as a Salvation Army band]]; turns out he never had cancer in the first place, to which he promptly celebrates by smoking the tobacco the rest of the gang was smuggling. The moral can best be summed up as "Smoking is bad for you, unless you're the Main Man".

[[folder:Comic Strips]]
* Deliberately {{invoked|Trope}} by ComicStrip/{{Dilbert}} in [[http://dilbert.com/strips/comic/2006-08-05/ this comic.]] Apparently, this is the only way to assure his clueless managers make reasonable decisions.
-->'''Dilbert:''' If we don't upgrade our servers, a herd of trolls will attack our headquarters.\\
'''Manager:''' No trolls!

[[folder:Fan Works]]
* In ''Shadow Snark'':
-->Sometimes you have to tell your friends they suck at everything, otherwise they'll blow up a laundromat.
* ''Fanfic/YouGotHaruhiRolled'' gives the moral of always being nice to minor characters, lest they befriend the bad guys and destroy the world. Also a SpoofAesop because it's a CrackFic.
* The lesson of one plot arc in the ''Film/{{The Avengers|2012}}'' fanfic [[http://archiveofourown.org/works/657592/chapters/1198458 "Multicolored,"]] which deals with Bruce Banner's (canonical in the comics) DarkAndTroubledPast and the psychological aspects of the Hulk, is "be sensitive to other people's PTSD, because if you insist on dredging up traumatizing subjects and trigger them too hard, they could turn into a giant technicolor rage monster."
* ''FanFic/TheEndOfEnds'': You can never truly change who you are, and even if you ''do'' change, you are who you are and that can’t change. It had to take an OmnicidalManiac who was destroying the universe to hammer that into Terra's head.
* ''FanFic/SonicXDarkChaos'': Don't believe in Christianity or Islam or Judaism, or else you'll be manipulated by evil aliens into fighting a ForeverWar and/or be eaten by Shroud parasites.

[[folder:Films -- Animation]]
* ''WesternAnimation/{{Frankenweenie}}'' has the moral, delivered by a teacher, that science is morally neutral--whether it turns out good or bad depends on how you use it. The thing is, it portrays that message very literally: the main character resurrects his dog [[ThePowerOfLove out of love]] and the dog is fine, if still [[NonHumanUndead less than fully alive]]. The {{Designated Villain}}s do the same experiment [[AmbitionIsEvil to win a science fair]], and all of ''their'' pets ComeBackWrong.
* ''WesternAnimation/JimmyNeutronBoyGenius'': "Don't talk to strangers or aliens will kidnap every adult in town, including your parents." Or "appreciate all that your parents do for you (or they'll be abducted by aliens)."

[[folder:Films -- Live-Action]]
* The {{Trope Namer|s}}: ''Film/StarTrekIVTheVoyageHome''. The intended aesop is "don't assume you can use up Earth's natural resources without consequence, since someday your survival might depend on them," but an early draft involving a plague in the 24th century whose cure was lost in the destruction of the rain forests was considered unworkable, and director Leonard Nimoy found whales to be majestic, so the much more entertaining aesop of "save the whales or else a gigantic SpaceWhale probe will appear out of nowhere to destroy Earth" was born.
* ''Film/TheHappening''. Preserve the environment, or else [[spoiler:the plants may get pissed and release a deadly neurotoxin into the [[strike: [[VideoGame/{{Portal}} Enrichment Center]]]] air that makes you kill yourself]].
* Standard in horror movies with a DeathBySex message, since showing real negative consequences of sex is often non-dramatic (even deadly [=STDs=] take years or decades to kill) or, worse, X-rated. These aesops range from from [[DeathBySex "have sex and Freddy or Jason will kill you"]] to "the SealedEvilInACan can only be opened by two people having sex on top of it (even if they don't know what it is) to "if you have sex, then you will shock and horrify your six-year-old sister whom you didn't know was watching, causing her to becoming depressed and making her vulnerable to PuppeteerParasite".
* ''Film/{{Teeth}}'' evokes an old Space Whale Aesop: "Don't rape a girl, or the teeth in her vagina will bite off your dick." Also, "...and the audience will cheer her on because you deserve it!"
* ''Film/{{Daybreakers}}'' makes this work by making it a rather broad Aesop: "Conserve your resources and be nice to the people who produce them for you, or your society will descend into chaos and you'll end up a lot like all these starving vampires." Granted, you won't be starving for ''blood'' specifically, and that descent into chaos probably won't involve a ZombieApocalypse like theirs; in all other respects, however, the point stands.
* ''Film/TheDayAfterTomorrow'': Cut down on greenhouse-gas emissions or the Earth will enter a new ice age and New York City will freeze solid--By the ''end of this week''. And deadly sub-zero frost lines that instantly turn anyone into a HumanPopsicle will ''hunt you down!'' Furthermore, in case that wasn't a tangible enough deterrent, said ice age will also cause wolves to escape from a zoo and come after you and your family. Also (once you've learned your lesson), Earth's entire climate will start being nicer to you again if you'll start being nicer to third world countries.
* ''The Day the Earth Stood Still'': [[Film/TheDayTheEarthStoodStill1951 the original]] called for humanity to abandon its reckless nuclear aspirations if it ever wants to travel into space without getting obliterated by {{Sufficiently Advanced Alien}}s. [[Film/TheDayTheEarthStoodStill2008 The remake]]? Aliens just want to obliterate humanity to "help the environment". In the original, Klaatu even states that his race didn't care in the slightest what humans did on their own planet…but human affairs officially became their problem when the first space missions were launched with humanity capable of creating nuclear weapons. Seems the reason for the change might be, that real life humanity got the message from the original and decided to give up space travel beyond low Earth orbit.
* ''Film/TheAbyss'' (director's cut): Yet again, but with awesome special effects. Also: If you make up with your estranged wife, then you can prevent submarine aliens from killing everyone.
* The made-for-television holiday film "The Night They Saved Christmas" is not terrible, but it's based on this kind of Aesop: Don't drill in the Arctic Wildlife Refuge because you might harm Santa's workshop. And then [[spoiler: it goes ahead and breaks its own Space Whale Aesop]]!
* ''Film/TheDayTheEarthCaughtFire'' (1961) warns that atomic testing could send the Earth spinning out of orbit towards the Sun. The bad science is somewhat offset by the 'documentary-style' realism of the story.
* ''TheCrackInTheWorld'' warns in the utmost seriousness that atomic testing could literally ''split the Earth in two''.
* Invoked in-universe in ''Film/{{Watchmen}}''. [[spoiler: Adrian's message to earth: stop fighting or ''Dr. Manhattan will come back from space and make you DIE.'']]
* ''Film/{{Prophecy}}'' teaches us that if you let paper mills pollute nature, it will create killer mutant bears that will hunt you down.
* Creator/EliRoth films: stay at home, around people you know, because if you go anywhere on vacation, you will either catch a flesh-eating virus or be dissected alive for sport.
* ''Film/CyberSeductionHisSecretLife,'' don't ever look at even the softest of softcore porn or your girlfriend will dump you, you will suddenly suck at whatever you were good at before and the kids you thought were cool will beat the shit out of you.
* ''{{Film/Birdemic}}'': If you contribute to global warming, birds will develop acidic spit and WWII bomber engines, and attack people at random.
* ''Franchise/{{Godzilla}}'':
** [[Film/Godzilla1954 The original film]] and its fellow [[{{Kaiju}} giant monster movies]] can be perceived this way: [[ILoveNuclearPower The use and/or testing of nuclear weapons invariably mutates ordinary creatures]] [[AttackOfThe50FootWhatever into horrendous monsters that are almost as destructive as, well, a nuclear weapon]]. (But against ''your'' side!) Of course, the Japanese audience of ''Godzilla'' didn't need to be persuaded against atomic bombs, so that particular movie is as much an ''allegory'' of the known effects as it is a warning; the American imitations are thus closer to this trope.
** ''Film/MothraVsGodzilla'': [[GreenAesop Take care of the earth]] and don't be [[CorruptCorporateExecutive a greedy jerk]] or two giant moths will destroy your city.
** ''Film/Godzilla2014''. As usual to the franchise's origins as a metaphor. Building up nuclear arsenals results in [[NatureIsNotNice the awakening of ancient creatures]] who feed off of radiation, and any attempt to harness or fight back nature is met with a swift fate--and in the end, only the balance of nature itself (Godzilla) saves the world.
* ''Film/WRMysteriesOfTheOrganism'': Have sex, or else you will become a psychopathic murderer.
* Passed over rather quickly in ''Film/PacificRim''; Geizler mentions that the {{Kaiju}}'s [[spoiler:creators']] initial attempt to take over the planet failed owing to a lack of compatibility with the atmosphere, but now that humans have sufficiently polluted our planet, it's ripe for a batshit insane monster takeover. Go figure.
* ''Film/{{Waterworld}}'' basically shows the potential consequences of global warming by taking the whole "flooded coasts" thing UpToEleven.
* ''Film/{{Avatar}}'' gets its strong [[GreenAesop pro-conservation message]] across by inventing the world of Pandora, a flawless alien paradise untainted by technology. On Pandora, deforestation is depicted as evil because it nearly leads to the destruction of a sentient organic [[BrainComputerInterface mind-linking supercomputer]] that lets the resident aliens communicate with their dead relatives, and nearly everything that humans had to develop through technological advances--medicine, transportation, shelter, and even ''data storage''--is naturally provided by the [[GeniusLoci living ecosystem]]. It's easy for the Na'vi to preach about respecting the environment when their environment apparently supplies them with all the perks of an industrialized society.
* The horror anthology film ''Film/BodyBags'' does this in the segment "Hair". Being so insecure about hair loss that one is willing to try out mystery experiments will result in [[spoiler:becoming a host for parasitic wormlike aliens who will snack on your brain]].
* ''Film/ReeferMadness'' is an interesting example because, while the effects of marijuana were not widely known when the film was made, the guesses the film made are known today to be an exaggeration at the best of times, and often plain wrong.
* ''Film/GameraVsZigra'': Pollute the oceans and a Nazi space fish will attack the planet, supported by a {{Brainwashed}} Japanese woman in {{Fanservice}}y clothes. Also our only hope for surviving this attack is a giant monster. There are, shall we say, certain issues with trying to mix philosophical discussions with {{Kaiju}} beating the snot out of each other.
* ''Film/BrideOfTheMonster'' teaches us that if you toy with nature (or, as the film puts it, "tamper in God's domain"), you might end up blowing up in a nuclear mushroom cloud.
* ''Film/{{Harmless}}'' is about a sentient PornStash that harms its owner's family. Say what you will about the moral itself, but it breaks down somewhat since real porn stashes, um, aren't sentient.
* ''Film/Plan9FromOuterSpace'': We must control our urge to develop a BiggerStick in our LensmanArmsRace, or a small group of incompetent aliens will attempt to wipe out our species by raising the dead so they'll attack us, thus preventing us from developing a bomb that can [[ApocalypseHow/ClassX4 destroy the entire universe]].

* Parents sometimes use these to [[ScareEmStraight scare their kids straight]]. For example, TheKrampus of Central Europe is one such bogeyman with his own page on this wiki.
** The residents of Creator/JasperFforde's "Cautionary Valley" (under the Literature section) come from these scare-tales. Fforde's interpretation of the Scissor Man is fairly tame, though. He's a pussycat compared to the one in ''Discworld/{{Hogfather}}'' -- an emu-like being composed entirely of scissors.
** ''ComicStrip/CalvinAndHobbes'' also riffed on one of these, namely "Don't make that face or it'll [[FrozenFace stick like that]]." After hearing that warning from his mother, Calvin was [[ThreatBackfire thrilled]] at the prospect of becoming a horrific freak. He only stopped making the face when he realised that people weren't as shocked as he'd hoped.
** The Ancient Romans famously used Hannibal Barca as their resident bogeyman, telling their naughty children that "Hannibal ante portas" (Hannibal is at the door). It must be a bit of a let-down for one of the greatest military minds in history to be reduced to a children's fable.
** And Greg's dad in ''Literature/DiaryOfAWimpyKid'' warned: "If you get out of bed again tonight, you'll probably run into Creator/ShelSilverstein in the hallway." ItMakesSenseInContext, since that happened after a very young Greg had seen [[https://img.buzzfeed.com/buzzfeed-static/static/enhanced/webdr01/2013/7/29/12/enhanced-buzz-orig-27163-1375114225-60.jpg a very threatening photo of Silverstein]] on the back cover of ''Literature/TheGivingTree''.
* In his book ''Wisdom of the Elders: Sacred Native Stories of Nature'', David Suzuki recounts a Chewong fable of the perils of disregarding the natural order. A childless man and wife were walking through the forest when they spotted a [[RidiculouslyCuteCritter squirrel]]. In their loneliness, they unwisely disregarded that this animal was part of the natural order, and brought it home with them as a pet. [[DisproportionateRetribution Suddenly, the hundred-foot-tall snake god Taloden asal burst forth from her eternal subterranean slumber and]] [[YourSoulIsMine ate their souls]]. The end.
* According to some corners of the Internet, every time you masturbate, God kills a kitten. According to certain Native American mythologies, women who masturbate give birth to monsters. [[DoubleStandard But it's totally fine for men to do it]].
* According to the Internet, every time you try to apply physics to a fantasy setting, God kills a catgirl.
* There are great many fairy tales and ancient legends about how you should be nice to strangers, especially because they [[AngelUnaware might secretly be angels/gods/witches/whatever]] who will use their magic to grant those who treated them kindly with fantastical rewards beyond their wildest dreams while inflicting horrifying curses on those who treated them cruelly, selfishly, or apathetically.

* Pretty much every moral lesson in the German moral children's book ''Literature/{{Struwwelpeter}}'' works this way.
** Thumb-sucking summons up a scissors-wielding tailor who [[{{Fingore}} snips off the offending digits]]; fussy eating habits result in death by starvation; and going out in a rainstorm to play leads to being hurled away to your doom by a sudden gust of wind. There is also a girl who ends up as a pile of ashes after playing with matches despite admonitions from her parents and her two pet cats. And many similar.
** {{Deconstructed|Trope}} in Creator/JasperFforde's ''The Fourth Bear'', one of the Literature/NurseryCrime series, with "Cautionary Valley." The series takes place InAWorld where fictional characters come to life; the valley is a favourite haunt of Aesop-delivering Space Whales, led by the aforementioned scissors-wielding tailor. Children raised in this neighborhood are well-behaved to a [[StepfordSmiler downright creepy level]]. Prior to the events of the book, the parents ''[[UtopiaJustifiesTheMeans were perfectly fine with it]]''.
* Pretty much every punishment in Dante's ''Literature/TheDivineComedy'', especially, of course, those featured in Inferno.
* AIIsACrapShoot: a lot of stories that use this trope as their premise basically end with "A.I. research is dangerous, since A.I. will invariably become homicidal tyrants determined to enslave or destroy the human race." Parodied in Creator/JohnSladek's ''Literature/RoderickAtRandom'', which is told from the point of view of the world's one artificially intelligent robot. One conversation he has goes (roughly):
-->'''Scientist:''' Well, we of course we can't risk researching A.I. We've run simulations, and it could turn out they get so smart that they realize they don't need humans and decide to wipe us out.\\
'''Roderick:''' Or, they could get so smart they realize wiping out other species is pointless.\\
'''Scientist:''' Oh, I didn't say there were no counterarguments.
* ''Adventures of the Rope Warrior'' tells us you should exercise regularly and eat right. That way aliens can't harvest your body for the impurities a sedentary life inflicts to fuel their intergalactic drug trade, and the Space U.N. won't decide destroying the entire planet is an acceptable price to pay for getting rid of the drug dealers.
* In a number of Creator/HPLovecraft's stories, the lesson we're supposed to learn is "[[FamilyUnfriendlyAesop Don't breed with other races]], or your town will be corrupted and your kids will be demonic mutant freaks." By "other races" he meant, of course, [[ValuesDissonance people with skin colors different from your own]], but in the actual stories this was expressed more as "monstrous fish people and tentacular {{Eldritch Abomination}}s" and the corruption would often take the form of some kind of [[ReligionOfEvil ancient crazy pagan cult]]...Yeah, [[{{Understatement}} he was a bit of a racist]]...If anything, the real lesson of these stories was [[BestialityIsDepraved not to screw fish]], which is just common sense, really.
** And given the proliferation of naughty tentacles, furry fetishes, and other things, even the Space Whale Aesop is becoming ValuesDissonance.
* ''Literature/UnLunDun'': Don't pollute, or else the smog will become sapient and take control of people's minds, making them destroy a fantasy world and then ours.
* ''Literature/StateOfFear'': Don't give in to people believing in global warming, or ecologists will destroy the planet with their weather-control machines. And do not blame the civilization for all evil or you will be eaten by Papua-New-Guinean cannibals. Attack a Sci-fi author's book because you disagree with his doubts about global warming, and he'll give you a cameo as a child molester in his next book.
* ''Literature/MyTeacherFlunkedThePlanet'', a children's book. Stop all war and feed the hungry, or else aliens will destroy Earth. The first two books (''Literature/MyTeacherIsAnAlien'', ''Literature/MyTeacherFriedMyBrains'') were suspense/adventure books with no moral to preach, but the preachy moral showed up in the third book, which has at least one good, long AuthorFilibuster about how HumansAreTheRealMonsters. Although there was also a hidden one in here--TV rots the mind. Specifically, an alien taught us how to make TV to slow down our technological development, in hopes that we might resolve societal problems before we got to space.
* The moral of Coleridge's ''Literature/TheRimeOfTheAncientMariner'' is "be compassionate towards all creatures and don't go around murdering innocent seabirds, or else you'll wind up stranded in the middle of the ocean, all your friends will die, their corpses will torment you, and when you eventually make it to land you'll be forced to constantly wander the world telling your story instead of being able to live a normal life." Music/BruceDickinson put it best. "And the moral of this story is: This is what not to do if a bird shits on you."
* Some of Creator/EnidBlyton's stories for younger children. For example, ''The Magic Lemonade'': "Don't torment insects, or you might get shrunk by magic so that insects can torment you". ''WesternAnimation/TheAntBully'' has this same trope, sans lemonade.
* ''Literature/LogansRun'': Don't become a hippie. Hippies want to get everyone stoned, destroy the family, raise children in creches, revoke age-of-sexual-consent laws, and kill off everyone over twenty-one (raised to 30 in the movie).
* Pretty much any and all BeCarefulWhatYouWishFor stories end this way, most notably ''Literature/TheMonkeysPaw''. Among other examples, wishing to have money resulted in the family [[spoiler:having their son die in a terrible industrial accident, followed by them receiving tons of money in compensation from the factory]]. Wishing you had more money is not wrong or dangerous just because a cursed artifact interpreted the wish to negative results. If anything the real Aesop is "[[JackassGenie Genies are jerks]]." In the case of ''Literature/TheMonkeysPaw'', the Aesop intended by the character who created the paw was [[YouCantFightFate "those who defy fate do so to their sorrow."]] Because apparently fate is a {{Jerkass}}.
* The book ''Chocolate Fever'' by Robert Smith does this. It's about a boy who eats chocolate with everything and then one day he breaks out in a chocolate rash.
* Similar to the above is ''The Chocolate Touch'' by Patrick Skene Catling: "Don't eat too much chocolate, or [[TheMagicTouch everything that touches your lips will turn to chocolate."]]
* ''Literature/CaptainUnderpants and the Perilous Plot of [[UnfortunateNames Professor Poopypants]]'': Don't make fun of people's names, or else they'll shrink you to the size of a bug and make you change ''your'' name to something absurd to make themselves feel better. Although this could just be a way of saying, "Don't make fun of people, because what goes around comes around." This is lampshaded by the characters at the end as their only time their story had a moral, but the narrator then points out the FantasticAesop driving the entire story: never hypnotize your principal or he'll believe he's a superhero every time he hears the sound of someone snapping their fingers.
* In [[Myth/KingArthur Arthurian Legend]], the origin of Merlin involves his mother (a nun) being raped by an [[HornyDevils Incubus]] at night…because she [[UnfortunateImplications had an argument with her sister and neglected to say her nightly prayers that night.]] So don't forget to say your prayers, and don't argue with your siblings, or you'll be raped by [[HornyDevils demons]]. This may be a case of [[ScienceMarchesOn knowledge marching on]]; the moral would make sense for people who believed that demons are real and saying prayers really will protect you from them, which people likely did back when the legend was born.
* Babette Cole's ''Literature/WinniAllfours'' has quite a bad one for parents. The heroine's mother and father won't buy her a pony and make her eat lots of vegetables. Except that Winni works out that by eating all her greens, she'll turn ''into'' a pony! Once that's done, she's no longer dependent on her parents. So what kind of moral can we learn from that? "Don't try imposing limits on your kids, because they'll still succeed and it'll be all the worse for you?"
* ''Literature/TheAdventuresOfPinocchio'': "Don't skip school and have endless fun, or else you'll change into a donkey." Then again, "Don't slack off or you'll turn into an ass" is a pretty valid aesop.
* The tale of King Midas has the message "If you desire gold too much, you'll turn your loved ones into statues." Only if you read it ''very'' literally, which is not the point of Greek fables. The actual moral is "If all you care about is wealth, then wealth will replace all you care about". It's a mundane Aesop made fantastic.
* Some ValuesDissonance might be at play here, but most {{fairy tale}}s (in their original form, that is) might come across as this to modern-day audiences. How often do birds peck peoples' eyes out in the real world?
* Quite a few novels for children have the admirable goal of wanting children to appreciate the importance of learning history and/or appreciating their parents. The method they use is to have the juvenile protagonist get stuck in the crapsack past because they dared not to want to learn history or didn't appreciate their parents. So you have books like ''Literature/TheDevilsArithmetic'' (Nazi death camp) ''Tune in Yesterday'' (racism in 1920s) and lots of books about being a slave in the 1800s.
* Intentionally used in Creator/EdgarAllanPoe's short story "Never Bet The Devil Your Head", as part of the SpoofAesop. The reason it provides for the eponymous moral is that the devil might one day come to collect.
* There's a picture book called ''You'll Be Sorry'' by Josh Schneider in which the parents of a girl named Samantha tell her to stop hitting her little brother or she'll be sorry. She ignores them and the little brother cries so much that he floods the entire town.
* ''Literature/TheTimeMachine'' by Creator/HGWells is based on his socialist beliefs, and the central message is that, if the upper classes continue to oppress the working classes, the upper classes will evolve into pampered babies while the working classes will become cannibalistic monsters. At the time it was published, it was less space-whaley--both socialism and evolution were in their infancies at the time, and it seemed entirely possible that [[LamarckWasRight forcing people to work in unlit factories would turn them into cave-dwellers]]. Now, ScienceMarchesOn and SocietyMarchesOn, and TheReveal seems rather less plausible.
* ''Literature/TheCandyShopWar'' has the rather straightforward ''don't take candy from strangers'' as its message. It's even flat out said by one of the characters in the books--who then explains that these strangers might be wizards who are handing out magical candy and can very easily kill you. It also doesn't help that those strangers owned a candy shop and a ice cream truck. Almost makes it into a Space Dentist's Aesop: Don't eat candy or wizards will kill you. Who needs cavities when you have that?
* ''Heartlight''. Nothing lasts forever, and you had better accept this or else you could ''[[ApocalypseHow destroy the universe]]''.
* ''Literature/GalaxyOfFear: The Planet Plague'' teaches that obsessing over {{Revenge}} for your DoomedHometown is not Jedi-like, and if you have TheVirus it can speed your [[spoiler: [[BodyHorror transformation]] into a BlobMonster]]--when you're fighting, it's better to focus on what you're fighting ''for'' and ThePowerOfLove.
* The ''Literature/MrMen'' book ''Little Miss Bossy'' spells it out directly: don't boss people around or they will put magical shoes on your feet that force you to dance until you apologize.
* Literature/TheBible, Literature/BooksOfKings: Don't make fun of someone's baldness because they might call upon God to [[BearsAreBadNews summon bears that will maul you and your friends.]]
* Creator/RoaldDahl was rather fond of these.
** ''Literature/CharlieAndTheChocolateFactory'': Don't be a [[BigEater glutton]], a gum chewer, a [[SpoiledBrat spoiled brat]], or a [[NewMediaAreEvil TV fanatic]], or you will get sucked up a pipe, [[JaywalkingWillRuinYourLife inflated into a blueberry]], fall into a trash chute, or [[IncredibleShrinkingMan get shrunk]], respectively.
** ''The Magic Finger'': Don't hunt ducks, or you will wake one day as a winged human the size of a duck while the ducks will become humanoid and hunt ''you'' for sport.
** ''Literature/{{Matilda}}'': Don't be a [[SadistTeacher mean teacher]], or your smartest student will develop psychic powers with which to torment you.
** ''Literature/TheTwits'': Don't be jerks to your pets, or they will trick you into gluing yourself to the floor [[spoiler:and then you will shrink into nothing]].
** ''Literature/TheWitches'': [[TooSmartForStrangers Don't trust strangers]], because they might be witches who want to commit genocide on all children. [[FamilyUnfriendlyAesop Also, never bathe so witches can't smell you]].
** ''Revolting Rhymes: Jack and the Beanstalk'': Bathe every day so giants can't smell you. Guess you'll have to deal with those witches.
* ''Take a Good Look'' by Creator/JacquelineWilson: Obey your grandma's instructions not to go out alone, or you'll end up being taken hostage by armed robbers.
* ''Literature/ForYourSafety'': Protect the environment, or the robots will rise up, conquer mankind and imprison them in a GildedCage, and do it themselves.
* ''Literature/DoctorDog'': Don't let your father/father-in-law eat too many baked beans and drink too much beer at the same time, or else he'll fart the roof off.
* From the children's book ''[[https://en.wikipedia.org/wiki/A_Bad_Case_of_Stripes A Bad Case of Stripes]]'', the moral is to not let peer pressure prevent you from being yourself, especially if it comes to your favorite food, or you will become [[BodyHorror a multi-colored, multi-patterned, multi-growthed monstrosity]] that changes to the whims of everyone else.

[[folder:Live-Action TV]]
* ''Series/TheTwilightZone1959'' episode "[[Recap/TheTwilightZoneS5E150StopoverInAQuietTown Stopover in a Quiet Town" has Creator/RodSerling delivering one of the most hilarious space whale aesops ever, in the smirking, self-aware tone that only he can. The episode deals with a married couple who awaken after a drunken car crash and gradually realize that [[spoiler:they've been abducted from Earth and are now being kept as pets inside a giant alien child's model town..]]. Sterling was ''very fond'' of the IronicHell.
-->'''Rod Serling:''' [[BlatantLies The moral of what you've just seen is clear.]] If you drink, don't drive. And if your wife has had a couple, she shouldn't drive either. You might both just wake up with a whale of a headache in a deserted village... in the Twilight Zone.
* ''Series/DoctorWho'':
** "The Underwater Menace" has a ScriptWank where the Atlantean chief decides that religion and superstition was what got them into the state where they were following an ObviouslyEvil MadScientist, and decrees the temple should be buried and a new age of enlightenment should follow... "without gods. [[BreadEggsMilkSquick And without fish-people]]."
** "The Lazarus Experiment": If you don't test your new medical procedure before using it on yourself, [[spoiler: you'll turn into a giant human-eating scorpion monster]]. Also possibly a FamilyUnfriendlyAesop because it tries to claim that [[spoiler: trying to prevent people from getting old and dying makes you deserve turning into a giant scorpion]].
** "42": If you [[spoiler: accidentally use sentient creatures while mining for fuel]] you will be [[spoiler: possessed by their angry kin so they can stalk your friends and family like a serial killer before falling into the sun]]. [[ArsonMurderAndJaywalking Also, the Doctor will yell at you.]] Bonus for implying [[spoiler: things like the BP oil crisis or rainforest devastation aren't caused by big corporations killing things slowly, but by the equivalent of seven guys in a beat-up truck who didn't know anything was there to begin with]].
** "The God Complex": Be careful what you believe in, because [[spoiler: a monster that feeds on faith may eat you]].
** "The Bells of Saint John": Don't use strange Wi-Fi accounts or you'll be uploaded onto an alien computer server in the Shard.
** Don't structure your life around what you see on television or your face will be sucked off by Maureen Lipman.
** It is ironic that [[Recap/DoctorWhoS31E2TheBeastBelow the actual episode]] showing a space whale, containing a full-fledged [[AnAesop Aesop]], cannot be considered an example of this.
* The ''Series/OneStepBeyond'' episode "Forests of the Night" taught us that [[spoiler: dabbling in the occult will cause you to turn into a leopard]]. The ''Twilight Zone'' episode "Jess Belle" is similar.
* A bizarre {{inverted|Trope}} example from ''Series/SummerHeightsHigh'': drama-teacher Mr G. performs an energetic dance for his students, dressed in what looks like a giant white pillowcase. He asks his class what the dance represented. The correct answer was: [[spoiler: peer pressure]].
* ''Series/TheXFactor'' also has this trope applying to it [[http://www.dailystar.co.uk/news/view/156897/X-FACTOR-KATIE-S-NAKED-VID/ as seen here.]] Probably the biggest Space Whale Aesop the show has given out as a message--become a contestant and have your dirty laundry [[BleachedUnderpants literally launched into the limelight]].
* From an episode of ''Series/{{SCTV}}''--[[Literature/BenHur Jesus has magic healing booze]].
* An in-universe example in ''Series/{{Misfits}}'': Simon tries to persuade the others that giving up their powers is a bad idea, but since he cites the example of ''Film/SupermanII'', the rest hear "give up your superpowers and General Zod will destroy the Earth." It fails to persuade them.
* A sketch on ''Series/TheWhitestKidsUKnow'' features a kid Adolf Hitler being the nicest person in the entire town. In the last ten seconds of the sketch, he takes one bit of marijuana and suddenly wants to kill Jews.
* ''Series/BuffyTheVampireSlayer'':
** The episode "Beer Bad" combined an {{Anvilicious}} message about the dangers of alcohol with a plotline about cursed magical beer turning college kids into cavemen. It does lampshade it at the end, though:
--->'''Xander:''' And what have we learned about beer?\\
'''Buffy''': Foamy.\\
'''Xander''': ''[beat]'' Good. ''[cut to credits']'' I'm glad we had this talk.
*** This episode was actually made with the intention of getting a grant from the Office of National Drug Controller Policy which would be paid to shows that had an anti drugs or alcohol message but was rejected due to being "otherworldly nonsense".
** There's also this delightful exchange from "Reptile Boy":
--->'''Buffy:''' I told one lie, I had one drink.\\
'''Giles:''' Yes, and you were very nearly devoured by a giant demon snake. The words "let that be a lesson" are a tad redundant at this juncture.
* "As we often learn at the end of an episode of ''Series/MythBusters'', everyday objects can, in fact, be made lethal if Jamie builds a gun to shoot them."
* Future!Ted in ''Series/HowIMetYourMother'' sometimes gives these out: the reason they're fantastic is because they're ridiculously narrow because they're all about the five main characters ("Don't fight with Uncle Marshall, he's nuts." "If you hang out with Uncle Barney, you'll have great stories to tell.") and will only ever apply to his kids (and perhaps Marshall and Lily's kids).
* ''Series/PowerRangersWildForce'' had the initial message that humanity polluting the Earth helped make the Org spirits strong enough to return. It got even more Space Whaley when Animus showed up. "Humanity polluting the Earth will make our Mecha God mad and cause him to leave the world with the Power Animals and put Princess Shayla into a deep sleep forever." Other Power Rangers series often had Space Whale Aesops in filler episodes, like that if you tell lies all the time no one will believe you when an invasion of the body snatchers occurs and that sort of thing.
* InUniverse on ''Series/{{Frasier}}''--when Frasier challenges his father to give him a reason when perjury could be justified, his first response is "what if a comet was hurtling towards Earth, and the only way you could stop it was by lying under oath?" Subverted, though, as he goes on to give a very personal example from his own experience ([[BrokenAesop unfortunately]] it relies upon HollywoodLaw).
* On ''Series/MyNameIsEarl'', Joy tells an InUniverse tale to her kids to get them to behave and stop whining about having to do homework in the [[BottleEpisode "Creative Writing" episode]]. She (a beauty queen) flies the kids to the Crab Shack, and makes Earl fumble through one of those "If a train is going at X mph..." math problems. He gets it wrong, and they witness "Old Daddy" get hit by a train (the Crab Shack turned into a desert with train tracks.) Then they go back to the trailer, and they witness Randy being ThePigPen. Because he doesn't clean up, Randy gets CoveredInGunge on which moss grows, attacked by mice, and then everything from buildings to the Rocky Mountains sticks to him until he gets too heavy and falls off the Earth onto {{God}}'s desk and gets crushed by God's coffee mug. (And of course {{God}} tells Joy how beautiful she is.)
** Apparently, strict gun control isn't always good because you never know when you'll need to [[ItMakesSenseInContext shoot a couple of weather balloons to keep two men from floating too high and dying.]]
-->'''Darnell''': Yes, okay, when two men are floating away on a lawn chair tied to big balloons and one of them has left his parachute behind, that MIGHT be an okay time to have a gun!
* Invoked in-universe in ''Series/ArrestedDevelopment'', as part of Michael Bluth's HilariouslyAbusiveChildhood. George Bluth, Sr. apparently thought that the best way to teach his children important life lessons was to hire an amputee to pretend to lose an arm whenever they screwed up, teaching them that every mistake would lead to a man having his arm ripped off. Yelling too much while on the boat? A man will lose his arm. Forgetting to leave a note when you run out of milk? A man will lose his arm. Leaving the door open with the air conditioning on? [[NoodleIncident A man will]] ''[[NoodleIncident die]]''.
* ''Series/BreakingBad'': The creators would have us believe that protagonist Walter White is to blame for the TwistEnding of season 2. Ergo, the moral of the season is: don't deal drugs, kill people, and turn someone on their back while they're in a drug-induced sleep thus allowing them to choke to death on their own vomit, because that will inevitably lead to a mid-air collision which kills 167 people. Even the creator lampshaded the DiabolusExMachina in an interview.
* As a parody of "scared straight" programs, the ''Series/KeyAndPeele'' sketch "Consequences" has former gang member Donnie Herrera talking to an auditorium at a high school. He tells them how he did bad things (stealing, hanging out with tough kids, etc.) followed by him dealing with the consequences of this. The problem though is that the "consequences" are so wild and unconnected with the deeds he is guilty of that nobody takes any of it seriously.
--> '''Donnie:''' So I got really deep into crime. I did a drive-by at my own daughter's quinceaera! Yeah, shot up everybody-- dead, killed! Yeah! Yeah! Then I got sucked into a wormhole.
* ''Series/{{Misfits}}'': Don't play violent video games, or you'll get a superpower which makes you think real life is a game and become a mass murderer.
* ''Recap/BlackMirrorTheWaldoMoment'' is widely considered the weakest ''Series/BlackMirror'' episode because its message, "use your vote responsibly", is undermined by the far-fetched premise of a cartoon bear coming second in a UK by-election and eventually becoming the figurehead for a FascistButInefficient global government that takes over the world. Then again, considering three years after this episode's release [[UsefulNotes/DonaldTrump a reality TV star billionaire became the President of the United States on a wave of political cynicism]], maybe this idea isn't so far-fetched after all.

* Big Tent Revival's arguably most popular song, "Two Sets of Joneses": No matter how hard you work or how much your wife's father likes you, your marriage will fall apart very quickly if you don't have Jesus.
* Adam and the Ants' best known song, "Antmusic", features a moral possibly inspired by the Creator/EnidBlyton example above:
-->''Don't tread on ant, he's done nothing to you\\
There might come a day when he's treading on you!''
* "Grandma Got Run Over by a Reindeer" reminds us not to trust "[[SantaClaus a man]] who flies a sleigh and plays with elves." Okay, then.
* Music/{{Voltaire}}'s "The Mechanical Girl" leaves us with this very special message: "Never take a child away from a loving parent. Especially not ones who make children who shoot rockets from their eyes."
* The children's song "Little Rabbit Foo-Foo," whose Aesop is if you hit field mice on the head, you'll be turned into a "goon." You've been warned.
* Music/TheAquabats' song "Cat With Two Heads!" tells the very important Aesop that if you use your scientific knowledge to create a two-headed cat in an effort to make the world a better place (you can pet one kitty's head... [[MundaneMadeAwesome and pet the other kitty's head!]]), you'll wind up with a two-headed man-eating monster.

[[folder:Music Videos]]
* Music/{{Mastodon}}'s music video for "Curl of the Burl": don't snort the sawdust from a forbidden tree to get high or women will turn you into a log and set you on fire by flashing their breasts at you.

* Garrison Keillor plays with this in one of his Lake Wobegon speeches on ''Radio/APrairieHomeCompanion''. The "moral" is: spare the ant in your yard, or else radiation might mutate all of the ants into giant mutants that will trample your house.
* Parodied in one episode of ''Radio/TheHitchhikersGuideToTheGalaxy'': be careful what you say, because your words might travel down a [[OurWormholesAreDifferent freak wormhole]], get misheard by alien leaders at a conference as something insulting about one of them's mother, they'll end up going to war, eventually deciding the source of the problem is Earth which they team up to invade, and due to bizarre miscalculations of size, [[spoiler:end up getting swallowed by a small dog.]] And all because Arthur Dent is having terrible trouble with his lifestyle.
** And this is the series where a real whale appears in space as one of the unintended consequences of pushing a button.


[[folder:Tabletop Games]]
* ''TabletopGame/{{Monsterpocalypse}}'', drawing from B-movie sources, is built on this trope. The most obvious examples are the Radical factions, the Terrasaurs and Empire of the Apes. Respect the environment and live in harmony with nature, or a giant monster (supported by hippies with rocket launchers and apes with jetpacks) will eat you.
* In Franchise/TheWorldOfDarkness (both old and new): don't be a jerk, or invisible spirits will be unfriendly and at worst start attacking you. Conversely, be polite to your elders and don't even do harm in self-defense, because it will cause invisible spirits to like you and occasionally give you an hand.
** The KarmaMeter itself can get like this in some splats due to the odd way that sins are ranked and the penalties involved in decaying humanity: in a werewolf game, don't hunt for sport, because you will degenerate into a near-mindless brute restricted by a mystical ban on arbitrarily-chosen behavior.

* ''{{Toys/Bionicle}}'' has a message to politicians: if you're governors, then please do your job instead of appointing others to do it for you while you dedicate your life to something else, otherwise those appointed leaders may start a war, and your planet will explode. [[NuclearWeaponsTaboo That actually]] [[ApocalypseHow sounds pretty logical]].

[[folder:Video Games]]
* ''VideoGame/KingdomHeartsBirthBySleep'': If you and your family and/or friends don't communicate well, [[spoiler:a [[SatanicArchetype Satanic]] old man will get to ruin your lives]].
* While it's not a use of ScareEmStraight, ''VideoGame/MegaManStarForce'' offers fantastically ''positive'' consequences of ''following'' the Aesop. Why are friends important? Because they give you HitPoint increases and special abilities! Also, if you're lost in space on a dead satellite, they can direct you back home with electromagnetic friendship laser beams. Not that the franchise doesn't have more traditional examples. ''VideoGame/MegaManBattleNetwork 4'', for instance, explained that you should be good, because if you're bad, an asteroid controlled by a sentient computer program will destroy the planet.
* The moral of ''[[http://www.kongregate.com/games/larsiusprime/super-energy-apocalypse-recycled Super Energy Apocalypse]]'' is: Don't pollute, and do conserve energy, ''or else you'll be attacked by [[OurZombiesAreDifferent giant eyeballs]].''
* ''VideoGame/SuperMarioSunshine'':
** "Always remember to brush your teeth!" Said straight after cleaning the teeth of a giant eel boss with a water filled jetpack because it was polluting an entire bay with purple poison.
** "Remember, always be kind to your pets." If you're not, they'll turn into fireballs and cover the village in flaming goop. (Although those particular pets ''were'' treated kindly, they were just sick with fevers; their owner was clearly upset over how sick they were, which is why she forces you to help out.)
* ''VideoGame/SuperMarioBros2'' teaches us how vegetables are good for you--they can be used to kill enemies! This also can be [[UnfortunateImplications interpreted a bit differently...]]
* ''VideoGame/MajinAndTheForsakenKingdom'' reminds us not to pollute, and not to become greedy and power-hungry. Because if you do that, an EldritchAbomination will cause all your pollution to become sentient and [[TheCorruption corrupt]] everyone in the country into violent indestructible tar-monsters driven by their basest desires.
* According to the grand finale of the ''VideoGame/RiddleSchool'' series, you should always stay in school--because if you don't, [[spoiler:you'll set off a time-stop mine and inadvertently almost doom the entire planet to annihilation by an alien race]].
* ''VideoGame/AsurasWrath'': [[spoiler:Hey, don't overpopulate or pollute the planet or else a magma monster representing the will of the planet will mutate all of the planet's animals to kill all of us]]! Ultimately averted though. [[spoiler: Turns out the Gohma were created by Chakravartin, the creator God of the universe, to train the deities, and specifically Asura, to become the new God of Gaia. Pollution had nothing to do with it]].
* ''VideoGame/KidIcarusUprising'': Try talking things out first, [[spoiler:or you might end up freeing the most evil creature in existence, who will turn you into a ring for three years, possess a god, and start trying to wipe out humanity solely because it lives to spread destruction and chaos]].
* ''VideoGame/TalesOfVesperia'': If you don't use environmentally friendly technology, [[spoiler:a technicolor interdimensional ghost squid will come down from space and eat everybody]].
* The sponsored "Covert Ops" tasks in ''VideoGame/MarvelAvengersAlliance'' tend to have these, particularly the latest one, which was "Don't use knockoff cosmetics bought from shady street vendors, or [[CursedWithAwesome you may get super-powers]]."
* ''VideoGame/SonicTheHedgehog2006'': Be a strong leader who never cries in the face of adversity and trials... because otherwise, [[spoiler:you'll release a [[EldritchAbomination demonic monstrosity]] that was sealed within you and tear apart the space-time continuum]].
* ''VideoGame/LifeIsStrange'': Accept what happened in the past and move on, otherwise [[spoiler: your hometown and everyone you know in it will die to a {{Clock Roach|es}} tornado created by the universe meant to kill the person you keep trying to save with time travel]].
* ''VideoGame/{{Undertale}}'':
** The Genocide route is still incredibly horrific and effectively deconstructs the concept of grinding in [=RPGs=] and [[spoiler: killing characters you otherwise love in subsequent playthroughs just to see what happens]], but the very last scene takes it UpToEleven and turns the message of the playthrough into 'don't go murdering innocent people otherwise [[spoiler: [[DemonicPossession you'll get possessed by]] [[EnfantTerrible a creature of pure evil]] [[OmnicidalManiac and be forced to destroy the entire world]] [[ButThouMust whether you want to or not]]]]'. Made worse by the fact [[spoiler: said creature possesses your character in every subsequent playthrough and preventing you from ever achieving the GoldenEnding ever again, throwing a layer of FantasticAesop on top of that by implying 'you can't always use time travel to escape the consequences of your actions']].
** For the pacifist run: try to resolve issues not with violence, but by talking them out, or else you will be leaving an entire race to be trapped underground because [[spoiler:they would not all gather by the end so that the villain could use their souls (and six previous human souls) to have enough power to break the barrier keeping monsters trapped in should you talk him out of throwing reality in an endless reset loop to play with you because he confused you with his adopted sibling]].
* In ''[[VideoGame/NexusWar Nexus Clash]]'', the fact that smoking is bad for you is illustrated by cigarettes that do a few points of damage for every puff, such that it's quite easy to smoke yourself to death in a manner of minutes by smoking just a few packs. Given the [[BlackComedy nature of]] [[EverythingTryingToKillYou the series]] this may be ridiculous on purpose.
* ''VideoGame/MassEffect2'' gets one with an anecdote from DLC character Zaeed on the dangers of smoking:
-->"You smoke, Shepard? Don't. That stuff'll kill you. Knew a kid once, half your age. Smoked too close to a cache of explosives. Tossed a butt, blew himself sky-high."
** The trilogy's overall aesop can be summed up as "Don't mess around with artificial intelligence, or [[AttackOfThe50FootWhatever kilometer-long]] [[AbusivePrecursors ancient,]] [[SapientShip sentient starships]] will descend upon the galaxy to harvest your DNA and make more of themselves."

[[folder:Visual Novels]]
* ''VisualNovel/{{Snatcher}}'': Trust other people and be open to them, or a mad Russian scientist responsible for wiping out most of Asia may take advantage of the culture of suspicion around you to trial a new plan to replace people with killer robots indistinguishable from them except for a tendency to get skin cancer and they'll start killing everyone and then the government will want to nuke your island to get rid of them before they spread and ''then'' you'll be sorry.
* Nagito Komaeda in ''VisualNovel/SuperDanganRonpa2'''s free time event path hinges on accepting his [[UnluckilyLucky luck cycles]] being real, but the actual moral concerning "don't judge people with extremely bad and good luck" falls fairly flat thanks to how unacceptable the notion is in real life.

[[folder:Web Animation]]
* Bob's shorts on ''WebAnimation/WeeblAndBob'' tend to veer into this. According to "Penguins", you should "never leave your penguin unattended" in case it spontaneously combusts, and according to "Doods", the principle of "safety in numbers" will prevent you and your friends from being mauled by lions.

[[folder:Web Comics]]
* One story in ''Webcomic/{{Jack|DavidHopkins}}'' teaches the following moral: don't get consumed by anger against people who express bigoted views about you, or your partner might die from a demonic brain tumor that feeds on your anger. (Yes, the person in immediate danger is an innocent third party, not the one who did something bad.) Those familiar with [[Literature/TheBible the Old Testament]] can tell you that that notion is surprisingly accurate.
* ''Webcomic/ElGoonishShive'' has [[http://www.egscomics.com/?date=2002-06-24 Read or the Owl will eat you.]]
* ''Webcomic/GunnerkriggCourt'' has a [[http://www.gunnerkrigg.com/archive_page.php?comicID=598 chapter]] that seems to be leading up to an aesop about [[http://www.gunnerkrigg.com/archive_page.php?comicID=610 treating others the way you'd want to be treated,]] but instead it ends with [[http://www.gunnerkrigg.com/archive_page.php?comicID=632 this.]]
* In ''Webcomic/TheDogHouseDiaries'', [[http://www.thedoghousediaries.com/?p=207 Don't run with scissors.]]
* ''Webcomic/{{Homestuck}}'':
** [[http://www.mspaintadventures.com/?s=6&p=003819 This is exactly why babies should not be allowed to dual-wield flintlock pistols.]]
** Taking drugs to solve your problems and get around developing will result in you becoming [[spoiler:a sugar-like monster with a permanent grin that goes around trying to get your friends in to a four-way marriage and having an obsession with fancy Santas]].
* The first strip of ''WebComic/{{minus}}''. Don't bully the new kid, she might be a RealityWarper who will [[AndIMustScream imprison you with trees that appeared out of nowhere]].
* ''Webcomic/TheAdventuresOfDrMcNinja'': [[http://drmcninja.com/archives/comic/11p56/ "If you don't die when you are supposed to, really awful things will happen to you... in the service of Dracula."]] Maybe. He's not sure. [[AltText And death can come for you at any time, in the form of a moon laser.]] Other "Dr. [=McNinja's=] Final Thoughts" epilogues are similar.
* ''Webcomic/{{Sinfest}}'' [[http://www.sinfest.net/view.php?date=2012-08-12 explains]] that pornography is harmful because it makes you and your furniture crash through walls.
* ''Webcomic/{{xkcd}}'': If you use GOTO, you get [[http://xkcd.com/292/ attacked by a Velociraptor.]]
* DoubleSubversion in ''Webcomic/RustyAndCo''. [[http://rustyandco.com/comic/25/ Mimic starts to tell the Princess that she shouldn't smoke.]] Princess says that, A, her lungs, her choice, and B, they live in an RPGMechanicsVerse so she can just get somebody to cast a healing spell. [[spoiler:Then Mimic explains that monsters hunt by smell as an [[http://www.d20srd.org/srd/monsters/otyugh.htm otyugh]] comes up behind the Princess.]]
* ''Webcomic/SamAndFuzzy'': [[http://samandfuzzy.com/1756 No, the moral not "killing in self defense is justified".]] The moral is apparently "killing an assassin from an ancient ninja organization is justified" because it is so weird that morality stops applying, or something. (i.e. if things gets so weird like they only happen in comics, do as you please.)
* An in-universe example happens in ''Webcomic/QuestionableContent'', when it's revealed Clinton got his robotic hand after an childhood accident involving fireworks. As his sister notes, since he prefers his new limb to his original and doesn't regret losing it in the slightest, the moral of the story being "Don't play with fireworks!" has been warped into "Playing with fireworks can give you cool robot limbs!"
* [[http://imgur.com/gallery/0X1wx "The Impact Of Your Words":]] If you're polite and understanding to a person who's expressing their thoughts to you, the two of you will relate and become a couple [[spoiler:who together fend off an alien invasion]]. If you're rude and demanding to your partner instead, [[spoiler:Earth will be taken over by aliens]].
* ''Blog/SliceOfLife'' gives us:
-->'''Pumpkin Cake:''' I learned not to accept favors from semi-omnipotent beings of pure chaos.

[[folder:Web Original]]
* [[SpoofAesop Played for laughs]] in ''Website/CollegeHumor'''s [[http://www.youtube.com/watch?v=XFR07vsnWjA Extreme Anti-Smoking Ad:]] Smoking will cause [[spoiler:a RobotWar]]. It's also combined with DoNotDoThisCoolThing. Quite a few commenters found it awesome if smoking [[spoiler:turns them into badass killer cyborgs]].
* [[http://www.unicorn-dream.co.uk/destrier/Fiction/perfectsympathy.html Perfect Sympathy]] by "J.B. Burro" has the aesop "Don't mistreat your horse" or [[spoiler:you will suddenly wake up one day in your horse's place and your horse will be the abusive owner]].
* The website Kids-in-Mind doesn't do actual reviews but only a full list of material parents might find objectionable in a film, including violence, sex, profanity et cetera. Because one category for each write-up explains a movie's overall message, the site tends to offer up Space Whale Aesops when forced to find the "message" in explosive action movies, gory slasher flicks, and other genres famous for not really having many teachable moments. For instance, the message of the ''Film/EvilDead2013'' remake is "consult a professional before staging an intervention." Because if you don't, you'll unwittingly unleash an ancient evil and all your friends will die horribly and messily, you see.
* On ''WebVideo/VampireReviews,'' [[VampireVannabe Maven]] notes that she first saw ''Film/BuffyTheVampireSlayer'' on a church camp. The point was to open up a discussion about priorities in a person's life, but she interprets it as "If you're a shallow bitch vampires will slaughter everyone you care about. ''Be nice!''"
* Played for laughs in ''LetsPlay/TwoSaiyansPlay''. When Krillin is forced to play ''VideoGame/SlenderTheArrival'', he suggests there's an environmental message in the AbandonedMine level. Don't sell your land to mining companies or a [[HumanoidAbomination faceless monster]] will murder you and set up shop there.
* According to the r/nosleep story [[https://www.reddit.com/r/nosleep/comments/4k55jx/feed_the_pig/ "Feed the Pig,"]] if you commit suicide, [[spoiler:you will end up in a hellish place called the Black Farm, and the only way to get back is to be gruesomely devoured by a giant pig]].
* [[https://archiveofourown.org/works/6178036/chapters/14154868 Cordyceps]]: Obey people in charge who say they can't tell you something for your own good, or [[spoiler:you will be killed by alien brain parasites that kill humans who think about the existence of said parasites]].

[[folder:Western Animation]]
* ''WesternAnimation/FamilyGuy'' has a lampshaded version of this in which the ancient Irish race had vastly advanced technology. Then somebody invents whiskey, a few people take a sip, and crapsack island ensues.
* ''WesternAnimation/SouthPark:''
** "Free Willzyx" has a ''literal'' Space Whale Aesop: "If you mess with kids' minds, they will shoot a whale into space."
** "It Hits the Fan": "Don't abuse swear words or an EldritchAbomination will awaken!" (That said, the real aesop is more like "Swearing isn't wrong, but having certain words be taboo makes them more fun.")
** "Fun with Veal": "Eating veal is wrong because it is made from mistreated baby cows, but if you don't eat meat at all, you become a pussy." (yes, quite literally).
** "Funnybot" had perhaps the weirdest one of all. "Don't have comedy awards or a robot will destroy the world".
* The "moral" of the [[Creator/VanBeurenStudios Rainbow Parade cartoon]] "Grandfather's Clock"; don't play around with or smash clocks, because they have hearts and feelings just like you and me!
* Many episodes of ''WesternAnimation/CaptainPlanetAndThePlaneteers'', in a desperate attempt to [[{{Anvilicious}} hammer in the importance of the issues]], provide ludicrously overblown and immediate consequences for small-scale ecological harm. The main problem is the constant portrayal of pollution being caused by {{supervillain}}s ForTheEvulz.
* A British series that also aired in Australia and Canada, called ''WesternAnimation/GrizzlyTalesForGruesomeKids'', was MADE of this trope. Watch too much TV? You'll end up as a potato chip at the back of someone's fridge. Get arrogant and fail to do your schoolwork properly? A gremlin will destroy your brain's memory centers. This was fused with a jarring blend of Nightmare Fuel and [[ComedicSociopathy a claymation old man mistreating his pet spider, played for laughs.]]
** The last part is rather hypocritical, given the tale of the boy who tortured a string of pet spiders to death, only to end up with his innards invaded and occupied by the ghosts of the unborn children of one of his victims and [[ItMakesSenseInContext taking up knitting]].
* In the ''WesternAnimation/StargateInfinity'' episode "The Illustrated Stacey," the team goads Stacey into getting an alien tattoo by insisting that she's too boring to do such a spontaneous thing. (It should be noted here that Stacey has multiple piercings, blue lipstick, and a pink mohawk.) The Aesop is something like "don't do things just to prove yourself" or "think before you act"; but the reason for this moral is that the tattoo ink is made up of microbes that start multiplying, threatening to cover Stacey's body and kill her within the day. Fortunately, ''most'' real life tattoos do not contain deadly diseases. (And the ones that do take much longer to kill.)
* ''WesternAnimation/RobotChicken'':
** A sketch featured a mother telling her son [[Literature/IfYouGiveAMouseACookie that you shouldn't give a mouse a cookie]], or he'll turn into a vampire that will infect the country causing a nuclear war. That's why she killed her husband. He was giving a mouse a cookie.
** [[WesternAnimation/CaptainPlanetAndThePlaneteers "Protect the environment]], [[https://www.youtube.com/watch?v=uVzLzClY2E8 or I'll]] ''[[SoundEffectBleep f***]][[PrecisionFStrike ing]] kill you!''"
* On ''WesternAnimation/KingOfTheHill'', in one of the Halloween episodes, the resident {{Moral Guardian|s}} gets a group of children to go on a tour in her "[[TheMoralSubstitute Hallelujah House]]," showing various scenes of how she views atheists and "the Druids." One of them has a pair of actors talking about wanting to have pre-marital sex. The lady suddenly rotates the scene, now showing morgue cabinets with two pairs of legs marked HIM and HER. [[TruthInTelevision These are real, believe it or not.]]
--> "I guess the old saying is true: '''Sex kills.'''"
* In ''WesternAnimation/OzzyAndDrix'', the average boy that the characters live inside of [[HollywoodPudgy puts on a few pounds]] in one episode. Apparently, this is enough to have his otherwise healthy body nearly go into cardiac arrest.
* ''WesternAnimation/{{Trollz}}'' once had Ruby encounter a Space Whale BrokenAesop: It's always good to act nice and set a good example to your friends... [[spoiler: unless a magical spell has turned them evil anyway.]]
* Referenced in ''WesternAnimation/TheSimpsons'': Rod and Todd Flanders are watching a religious-themed educational show, but since the star characters are sheep, they don't see how their problems and solutions apply to humans.
* On one episode of ''WesternAnimation/{{Gargoyles}}'', [[MagicVersusScience the distinction between magic and science]] is discussed, with a focus on keeping your heritage alive--including the "magical" aspects of it. The Aesop works out as "Believe in your grandmother's teachings, or else a giant magic humanoid raven will destroy your land ForTheEvulz."
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' is set in a fantasy world and has AnAesop OncePerEpisode, so it is inevitable.
** [[SoOnceAgainTheDayIsSaved Dear Princess Celestia]], no matter how strong and smart you may be, there are some things you just can't do alone. Friends have a special bond that has more meaning than you can find in any book. So cherish your friends, nurture your relationships with them, and always hold them near and dear to your heart, because together you can smite evil with a badass rainbow WaveMotionGun. Because [[ExactlyWhatItSaysOnTheTin friendship... is magic]].
** Remember kids, it's better to give than receive--[[Recap/MyLittlePonyFriendshipIsMagicS2E10SecretOfMyExcess or else you'll turn into a giant greedy monster and practically destroy your hometown]].
** "Hearth's Warming Eve": You'd better get along with people different from you or evil ice elementals will freeze your land in an ice age.
** "A Canterlot Wedding": You should trust your instincts, because if somebody seems to be acting unlike themselves, they're perhaps being impersonated by a shapeshifting monster.
** "Bats": Be understanding of those whose needs conflict with yours, and also don't let your friends force you into something you feel uncomfortable about, or else someone is going to turn into a half vampire fruit bat and you're going to have to sacrifice your human-sized apple to turn them back.
* ''WesternAnimation/{{Futurama}}'':
** "Decision 3012" gives us "voting Republican will cause robots to rise up and destroy humanity."
** "I Dated a Robot:" Virtual romance is bad because the programs are really kidnapped celebrity heads forced to be illegally cloned in to robots.
* ''WesternAnimation/PhineasAndFerb'':
** The episode "Phineas and Ferb Get Busted" gives us "If you tattle on your brothers, they'll get sent to a military school where they'll have all their spirit crushed." Though perhaps justified as [[AllJustADream Candace dreamed the whole thing]]. [[DreamWithinADream While in a dream by Perry.]]
** The episode "The Chronicles of Meap" has the Aesop "Don't judge a book by its cover... or else you might mistake a cute-looking doll for [[spoiler:an intergalactic cop who can beat up alien poachers]]."
* Mundane pranks turning into supernatural problems is a pillar of ''WesternAnimation/RegularShow'''s plotlines.
-->'''Benson:''' I hope you've learned something from all this!\\
'''Rigby:''' Yeah. Make sure we do our chores so you don't narc on us to a giant eyeball.
* ''WesternAnimation/SpongeBobSquarePants'': "Jellyfish Jam" taught us not to bring wild animals home because if you do, those animals will apparently invite their buddies over to party.
-->"Wild animals throw very wild parties."
* ''WesternAnimation/DannyPhantom'' tells us not to cheat on a test, otherwise all of your friends and family will die and the future world will be ''completely destroyed by you.'' Also such gems as, "don't fight back against the bullies at school, or else the ghost of a dead kid from the 50s, who was bullied himself, will take over your body and trap your soul in a spirit world version of his high school," "don't let jealousy of a friend consume you, or you'll make a wish to have the thing that they have and become a raging ghost monster," "don't be a scrooge at Christmas, otherwise a ghost writer will shove you in a book and force you to accept Christmas for what it is," "don't refuse an offer to become an apprentice of someone you hate, or they'll plot to make a clone of you to become that apprentice," and "don't test your scientific experiments with your best friend standing right next to them without double checking everything's ready to go, otherwise they'll get hurt, become a half ghost, and plot to make you look like a sociopath and drive your wife away from you so that she'll marry your friend instead."
* One of ''WesternAnimation/GarfieldAndFriends''' U.S. Acres cartoons featured Roy leaving the farm to go into showbiz, and joining the [[TastesLikeDiabetes annoyingly edutaining]] Buddy Bears show to teach kids proper manners and hygiene habits. He played the Goofus to the female Buddy Bear's Gallant, and not only were the consequences ridiculous, but one of the Bears literally warned them as cause-and-effect relationships along the lines of "If you don't [do polite/clean/encouraged-by-parents'-groups behavior], a [random large heavy object] will fall on your head."
* ''WesternAnimation/DinoSquad'' generally treats global warming as a bad thing, but in one episode tried to tell us part of the reason we should work to prevent it is because otherwise some prehistoric danger that was frozen in ice will be defrosted, mutated by a supervillain, and destroy us all.
* ''WesternAnimation/TeenTitans'' had a few, usually attached to {{Bizarro Episode}}s.
** For example, [[Recap/TeenTitansS3E4Crash "Crash"]] had a DigitalPiracyIsEvil Aesop delivered by way of Beast Boy downloading a new video game and trying to play it on Cyborg's system recharger, which in turn infects Cyborg, giving him [[MeatOVision food-based hallucinations]] and then nearly destroys the city.
** [[Recap/TeenTitansS4E5EmployeeOfTheMonth "Employee of the Month"]] is either an anti-meat Aesop or an anti-[[spoiler:''Tofu'']] Aesop, depending on how one interprets the text. Namely, [[spoiler: Beast Boy takes a job at a disgusting restaurant that specializes in gelled meat--except the "meat" is sentient Space Tofu seeking to steal cows for fuel and destroy the earth because "It is our way."]]
* ''WesternAnimation/TeenTitansGo'', being a StatusQuoIsGod "wacky" show where anything can happen because it'll all be reset next episode anyway, has "don't try to make your friend who was pretending to be a ghost think he actually ''is'' a ghost to teach him a lesson, or he'll decide that since he's dead he can't get hurt any more and run off to jump in a volcano for fun, and while you're trying to stop him random lasers from outer space will kill half your party (the others will also die, but from more reasonable causes)".
** In "Smile Bones" we get the lesson to chew your food, or else your bellies will become sentient and eat everything in sight.
* Played humorously in ''WesternAnimation/TheAngryBeavers'' episode "The Loogie Hawk": if you remove a species from its natural habitat, the forest will fall apart. No, really, it will '''literally''' and immediately fall apart.
* ''WesternAnimation/{{Spliced}}'':
** {{Lampshade|Hanging}}d in "Roots": "I promise I'll never be lazy enough to turn into a tree again!"
** "Cleaning Up": "Have good hygiene or your dirt will take on a life of its own and try to replace you"
** "Stompabout" has two in-universe examples from Wingus about getting angry. Firstly that if he doesn't learn to control his anger, he'll become a cyborg and sink the island with his robot legs. The second that if he is ''too'' determined not to get angry, Fuzzy will become a SuperSoldier and take over the island (the latter became a ChekhovsGun in "Sgt. Snuggums", which itself was an example: "Don't play pranks on your friends or they'll turn into insane {{Super Soldier}}s who see everyone as evil robots that need to be destroyed")
** "Amazon": "Take proper care of your pets or they'll form their own civilization where you're a wanted criminal"
** "Juice": "Don't be too determined to be popular or all your friends will turn into juice-obsessed zombies"
** "Promises, Promises": "Fulfill your promises or your best friend will have his brain stolen by a MadScientist in order to power a toaster"
** "Taste of Friendship": "Don't be jealous of your friends or your mind will be taken over by an evil squid"
** "Sugar Low": "Don't eat too much sugar or time will stop"
** "The Mutants Who Cried Monster": "Admit to your mistakes or a giant robot will destroy your hometown"
** "Livin' La Vida Lava": "Don't use too much power or you'll trigger an ice age in which yetis become the dominant species"
** "Mo' Mayo, Mo' Problems": "Don't eat too much junk food or the junk food will eat ''you''"
** "Walkie-Talkie-Spinesuckie": "Think for yourself or a mad scientist will make you suck out all your friends' spines to feed a baby robot and then throw them in the volcano"
** "Whirrel Call": "Don't be cruel to animals or you'll swap brains with them"
** "Stomach on Strike": "Live a healthy lifestyle or your organs will become sentient and jump out of your body"
** "Bite, Shuffle and Moan": "Stay in bed when you're sick or you'll cause a ZombieApocalypse"
* ''WesternAnimation/GravityFalls'':
** "[[Recap/GravityFallsS2E5SoosAndTheRealGirl Soos and the Real Girl]]" takes the already questionable moral "[[DatingSim Virtual romance]] is bad, you should 'mature' and find real love" and adds "Because your AI girlfriend might be a [[AIIsACrapshoot sentient, psychotic]] {{yandere}}".
** "[[Recap/GravityFallsS2E16RoadsideAttraction Roadside Attraction]]" combines a reasonable moral ("flirting when you don't really mean it will only hurt people") with a somewhat less reasonable one ("also, it may get your juices sucked out by a spider-person who preys mainly on sleazeball pick-up artists").
* ''WesternAnimation/StevenUniverse'':
** "Steven and the Stevens": You shouldn't tell yourself to be something you're not, because then your time clones will make a band without you because you told them they aren't handsome. Then you'll get angry and try to erase them with your time thingy and then you end up fighting across all of time and space, until the original you realizes that the original original you is scared of all of it and breaks the time thingy, killing off everybody but the original original you who's holding a pile of sand that used to be the original you wondering what the fuck just happened.
*** The literal [[AnAesop Aesop]] for this according to WordOfGod is actually "Time travel is cool, and wouldn't it be funny if we killed our main character on screen like 60 times?"
** "Space Race": Sometimes, [[KnowWhenToFoldEm you just gotta know when to bail]]... out of a collapsing space rocket made of spare parts from your great-uncle's barn.
* ''WesternAnimation/RickAndMorty'': "Total Rickall" teaches us to appreciate the negative sides of our loved ones as well as the positive sides...because if you have only positive memories of someone, then that means they're shape-shifting alien parasites who have implanted false memories into your head.
* ''WesternAnimation/ReallyRosie'': If you don't care, your parents will leave you at home and you'll be eaten whole then vomited out by a lion that will end up staying for the weekend.
* ''WesternAnimation/ThreeTwoOnePenguins'':
** "Trouble on Planet Wait-Your-Turn": Wanting to go first all the time will only lead to trouble, like your planet slipping out of its orbit and heading towards the sun.
** "The Amazing Carnival of Complaining": If you ever complain, you'll literally turn into a seed of discontent and be used to depopulate a planet.
** "Moon Menace on Planet Tell-a-Lie": It's wrong to lie. Because if you do, the moon will flatten you and your planet.
** "The Green-Eyed Monster": Don't ever feel envious, or else green-eyed monsters will appear and start eating all of your shit.
** "More is More": You need to know when to say "enough", so that a giant space funnel won't threaten to consume your planet.
* ''WesternAnimation/StarVsTheForcesOfEvil'':
** The moral of "Mathmagic" seems to be "Even if you're not good at something, don't be afraid to try... otherwise you might [[GroundhogDayLoop get caught in a time loop]] or cause a RealityBreakingParadox."
** The moral of "Stump Day" could be "Respect others' holiday traditions, and don't ruin things over petty arguments... otherwise you might get attacked by a giant vindictive tree stump and threatened with bloody murder."
