->''"Now '''that's''' comedy!"''
-->-- '''Slappy Squirrel''' (at the end of every episode, and usually after a particularly nasty act of violence), ''WesternAnimation/{{Animaniacs}}''

A type of {{Jerkass}} who mercilessly pranks characters primarily for his own (and the audience's) amusement. This is sometimes over a minor slight where the character is annoyed that the perpetrator doesn't even acknowledge it.

Many writers of original animated shorts felt it was more [[UnsympatheticComedyProtagonist difficult to sympathize]] with an obviously clever lead doing this kind of thing too often. A famous comparison is the early "Creator/TexAvery style" WesternAnimation/BugsBunny, who was zany on sheer principle (or better yet, Creator/BobClampett's take on Bugs, which portrayed him as a manic, short tempered egotist who breaks down when met with someone of his own wile). Creator/ChuckJones turned Bugs into a KarmicTrickster. He was paired with bombastic or life-threatening antagonists who deliberately threaten or mistreat him without provocation. Given that he responds only in retaliation or in self-defense, Bugs was more easily excused for his behavior, and even then he tended to play on the stupidity of his enemies rather than outright aggression. A problem with this moral logic of the encounter was that it is always incredibly one-sided-- since Bugs is rarely in real danger, it shades into WhyDidYouMakeMeHitYou.

On the bright side, this kind of character will rarely, if ever, cause any permanent or serious damage to their victims, mainly due to the downtoning of this trope. Modern examples of this trope will usually result in a JerkWithAHeartOfGold, who, while causing other characters a lot of annoyance, will notice when they have gone too far [[EveryoneHasStandards even for them]]. They are trying to amuse themselves, after all, and some levels can flat out be disturbing even to them. Writers also frequently took pleasure in showing the odd occasion where such pranksters to [[HypocriticalHumor have absolutely no sense of humor]] when it is [[WhosLaughingNow they who act as the butt of a joke]], often leading to a HumiliationConga. If they have a favorite victim, on the other hand, they will usually be very protective of them should another similar-minded prankster show up and do the same on them, reasoning that it is only he or she is allowed to treat the victim in such a manner, which often leads up to a HypocriticalHeartwarming moment.

If the ScrewySquirrel is an otherworldly being, the character may also be an AmusingAlien or a GreatGazoo. A {{Troll}} is the online version of this trope. Often criss-crosses with ThePrankster who's focus is on practical jokes.

{{Media Watchdog}}s for {{Saturday Morning Cartoon}}s in the 1980s came down heavily on any remaining {{Screwy Squirrel}}s, citing them as bad influences on children; many revivals of them tend to be toned down considerably.

Not to be confused with CrazyAwesome.

* [[http://static.tvtropes.org/pmwiki/pub/images/Screen_shot_2010-11-27_at_10_48_5851.jpg Screwy Squirrel]], a Creator/TexAvery MGM character from the '40s for whom the trope is named. He at least had the excuse of being, well, screwy: One of the shorts starts with him escaping from an asylum and tormenting the asylum's guard dog while [[NapoleonDelusion wearing a Napoleon hat]].
** Perhaps best encapsulated in 1997, when Screwy Squirrel, on April Fool's day "took over" Creator/CartoonNetwork and refused to show anything but a repeat viewing of his short Happy-Go-Nutty while demanding his own animated series.
** Screwy Squirrel is so completely demented a character he came to scare his creator. There were only four or five Screwy Squirrel shorts made - and already the [[BreakingtheFourthWall Fourth Wall]] was in smithereens - before Tex Avery decided to stop using the character; the unlimited potential for utter insanity and chaos [[CreatorBreakdown unnerved the animation team]].It's particularly telling that the final short "Lonesome Lenny" featured Screwy running afoul of [[AndCallHimGeorge a dimwitted but friendly dog named Lenny who ends up hugging him to death]].
** Incidentally Screwy ''did'' gain his own animated series in the early nineties (segments placed alongside ''WesternAnimation/DroopyMasterDetective''), albeit renamed "Screwball Squirrel". Similar to Bugs, his sadism was toned down and made more [[KarmicTrickster karmic]].

[[folder:Anime and Manga]]
* Suiseiseki of ''Anime/RozenMaiden'' appears at first to be as aloof and proper as Shinku, but in actuality she loves nothing more than tormenting Hinaichigo with tricks and pranks. Really, [[NotSoAboveItAll her "properness" is about as deep as her paint job]]. She's more like a spoiled and [[TheOjou immature royal]] who is more than willing to smack around her "subjects." She only sobers up during life and death situations. She ''acts'' like this during common situations, she is easily [[AllLovingHero the most caring of the dolls anyway]] (it says something when she is the only doll who never even tried to become Alice out of fear of losing her sisters). When she snaps out of it, she snaps out of it ''hard''. There's even one instance in the drama [=CDs=] when she tries to rectify her behavior after realizing that she had gone too far.
* ''Manga/UruseiYatsura'': Ryoko Mendou (younger sister of Shutaro) loves to act like TheOjou, but in reality she's this. She loves pulling pranks, setting people up against each other, and generally causing utter mayhem for reasons boiling down to "it was funny" or "because". And she ''always does this''. Her antics include (but are not limited to): shoving someone she ''knew'' couldn't swim into the water, removing the ladder someone had used to scale a tree, putting firecrackers in the mouth of someone who was sleeping, encasing someone in a block of concrete, locking her severely claustrophobic brother up in a locker, planting bombs in a building where people were throwing a Christmas party she wasn't invited to, and goading people into climbing a giant tree and then launching that tree into the stratosphere (it was actually a rocket disguised as a tree) because they were not climbing the tree quickly enough for her liking… and more importantly it looked like they were having fun without her…
* ''Manga/HayateCrossBlade'': Amachi] Hitsugi, being the head of an AbsurdlyPowerfulStudentCouncil, often uses her powers to amuse herself, usually at the expense of others.
* ''Manga/AzumangaDaioh'': Tomo may be an unintentional version of this trope, strangely enough. She is a good example of what a {{Jerkass}} with [[AttentionDeficitOohShiny ADHD]] can become when she tries a bit too hard to be a GenkiGirl.
* ''Anime/HareGuu'': Guu is a DeadpanSnarker who spends most of her time pulling various pranks on Hale using her [[RealityWarper seemingly unlimited powers]]. With Hare + Guu being a [[WhatDoYouMeanItWasntMadeOnDrugs rather]] [[WidgetSeries screwy]] anime in the first place, the fact that one of the main characters is a Screwy Squirrel is to be expected.
* Yukari from ''Manga/RosarioToVampire'' is introduced as one (in addition to ''Tsukune's'' [[BiTheWay love rival]] for Moka's affection), but she gradually mellows out.

[[folder:Comic Books]]
* ComicBook/AmbushBug, from Franchise/TheDCU.
* Screwy Squirrels make pretty good comic book villains: [[Franchise/{{Batman}} The]] [[SelfDemonstrating/TheJoker Joker]] has had aspects of this in his character, especially when more in a VillainousHarlequin mode.
* [[Franchise/{{Superman}} Mr Mxyzptlk]], DependingOnTheWriter.
* ComicBook/TheCreeper, sometimes.

[[folder:Fan Fiction]]
* Eileen Fields in ''FanFic/FutariWaPrettyCureDragon'' is definitely this, though some of her pranks fall under VillainyDiscretionShot, particularly when she isn't seen in a particular episode and another character has to mention her to get her OnceAnEpisode prank quota in for that episode. [[spoiler:This eventually stops due to CharacterDevelopment, and this aspect of Eileen's character is revealed to be more of an act she puts on for plot-relevant reasons. It also becomes a ChekhovsSkill later on when Nobunaga Oda attacks Ichiban High directly... only to fall victim to numerous booby traps Eileen had laid all over the school, including one that unleashes a swarm of bats on him as [[ItMakesSenseInContext she taunts him by singing "Jingle Bells, Batman Smells"]].]]
* Fiona Johnson in the Naruto Crackfic ''[[http://www.fanfiction.net/s/4853093/1/Moons_of_Red Moons of Red]]'' is a deconstruction of the archetype.

* Creator/JohnWaters' ''ADirtyShame'' features a screwy, ''horny'' squirrel.

* Literature/GeronimoStilton's cousin, Trap, is a relentless prankster who teases his cousin whenever he sees him, when he isn't taking advantage of Geronimo's fame and fortune.
* [[Creator/DrSeuss The Cat in the Hat]] is a benevolent example. Played straight though with Mr. Fox in ''Fox in Socks''.
* ''Literature/JourneyToChaos'':
** Trickster gods in general are like this. Zaticana caused a CurseOfBabel because she thought it would be funny, Remoh terrorizes entire cities in the name of "performance art" and Tasio makes water pipes burst or fills buildings with skunks. However, they make sure nobody is hurt and they often have a TricksterMentor style ulterior motive.
** Aio is a high energy boy that loves messing with people, especially Eric. One time, he snuck up behind Eric while he was reading and shut the book on his head.

[[folder:Live-Action TV]]
* ''Series/StarTrekTheNextGeneration'''s ''Q'' is another non-cartoon example, and a perfect one; many a GreatGazoo falls into this category.
* Janitor in ''Series/{{Scrubs}}'' torments J.D. to an insane degree. His own amusement is at least ''one'' of the possible reasons. Other interpretations include him honestly feeling just as tormented by JD (which is sometimes the case, though not because J.D. ''wanted'' to) or that he actually sees him as a friend but is too screwed up and [[SociopathicHero socially awkward]] to properly show it (Something his actor believes). [[spoiler:The finale reveals that J.D. really ''did'' put the [[FelonyMisdemeanor penny in the door]] and the Janitor saw it was an honest accident, but by repeatedly lying about it, he failed the Janitor's SecretTestOfCharacter.]]
* ''Series/{{House}}'': Dr. Gregory House has been known to ruin people's lives for no reason other than that he found them annoying. The fact that the majority of his victims wouldn't be alive were if not for him is the only thing saving him from complete {{Jerkass}}ery.
* The ''Series/SesameStreet'' {{Muppet}} character Harvey Kneeslapper had some of these qualities, and parental concerns about this were one reason (along with his loud voice, which was hard on Frank Oz's vocal chords) why he was eventually dropped from the show.
* ''Series/CaptainKangaroo'''s Mr. Moose and Mr. Bunny Rabbit kind of fit this trope, too.
* ''Series/TheOfficeUS'':
** Jim Halpert can verge into this. He tends to play pranks on Dwight and Andy out of boredom, but occasionally because they're driving him crazy and pranking them allows him to turn their insanity into comedy. How sympathetic Jim is depends a lot on how funny his pranks are and how much the victims did to deserve them that episode.
** In one episode Dwight discovers a box full of his grievances against Jim for this that he thought Toby had been sending to corporate. As Michael read through the list, Jim commented that these didn't sound nearly as funny back to back. Since then, he has occasionally been shown being nice to Dwight, or having his pranks backfire, or even being the victim of the occasional prank by Dwight. He takes it better than most Screwy Squirrels do.
* He takes this from his counterpart in ''Series/TheOfficeUK'', Tim Canterbury, who played pranks on Gareth to try to cope with the soul-crushing boredom of working in the office environment.
* Niles the butler from ''Series/TheNanny''. While normally his actions are limited to [[ServileSnarker bitter sarcasm]], his life's passion seems to be playing cruel tricks on [[RichBitch C.C. Babcock.]]
* Alluded to in an early season of ''Series/MythBusters'': the animated intro to the myth of whether you could stop a bullet by putting your finger in the gun barrel depicts stoic Jamie as an Elmer Fudd-like hunter and goofy Adam as a cartoon squirrel.

* "Star Invasion" by Music/{{Helloween}}.

* ''Pinball/NoGoodGofers'' have Bud and Buzz, the aforementioned gofers of the game.
-->'''Buzz:''' "Go pound some sand, hacker!"
* Earlier than them is Gunther the Gopher of Creator/{{Gottlieb}}'s ''[[Pinball/TeedOff Tee'd Off]]'', whose only purpose is to taunt the player and distract him from his golf game.

[[folder:Religion and Mythology]]
* OlderThanPrint: Loki in Myth/NorseMythology comes off as this, since his motivations are rarely explained. Why did he cut off Sif's hair? Why did he kill Baldur? Nobody knows.

* Cirque du Soleil's ''Mystere'' has Brian Le Petit, the principal clown, who is explicitly described in [[Main/AllThereInTheManual the backstory]] as an intruder of the MagicalLand the show takes place in. He constantly teases the pompous emcee (at one point successfully tricking him into stepping off a high ledge), pretends to lead audience members to their seats only to lead them on a roundabout path, steals their popcorn, and in the long climactic scene [[spoiler:tricks a man from the audience into climbing into a crate, which Brian locks so he can ''woo the man's date'']]. Nothing toned down about him, and most audience members ''love'' him for it. Once his plan starts falling apart, his increasingly absurd efforts to save himself edge him towards CrazyAwesome status. [[spoiler: In the end, he's tossed out of the show and doesn't appear in the curtain call.]]
* Launcelot Gobbo, the clown in ''Theatre/TheMerchantOfVenice'', seems to genuinely love Old Gobbo, his aged, blind father. Which doesn't stop him from practicing deceptions on Old Gobbo's blindness when the poor guy doesn't recognize him, finally informing him that ''his son has died.''
* Comes up occasionally in the Commedia dell'Arte, although with so much of the plays DependingOnTheWriter, it varies who it is--usually either Harlequin or Pulcinella. Any clever zanni, really.
* Puck in ''Theatre/AMidsummerNightsDream'' is this most of the time, although Oberon generally tries to employ him as a KarmicTrickster (for Oberon's definition of karma). However, he's introduced as a prankster who plays tricks on travelers, self-serious old ladies, and random horses, he transforms Bottom's head into that of an ass [[ItAmusedMe just for the fun of it]], and he's thrilled when it turns out he's given love potion to the wrong Athenian, so he fits this category much better.

[[folder:Video Games]]
* ''VideoGame/{{Touhou}}'':
** Tewi Inaba. Despite leading most of the youkai rabbits in Eientei, she is said to have a deceitful personality (this is later shown when Reisen Udongein Inaba arrives at Eientei, and Tewi often pulls pranks with her as the victim). {{Fanon}} takes it so far that she pulls pranks on ''everyone'' (mostly the lower-leveled girls), though canon and semi-canon shows that this isn't far from the truth, with her victims in both ''[[AllThereInTheManual Bohemian Archive in Japanese Red]]'' and ''[[ComicBookAdaptation Inaba of the Moon and Inaba of the Earth]]'' having included [[IntrepidReporter Aya]], [[TheGuardsMustBeCrazy Meiling]], [[TimeAbyss Eirin]], [[{{Ojou}} Kaguya]], [[ThePhoenix Mokou]], [[PhysicalGod Suwako]], and [[GodModeSue Yorihime]]. Strangely, her power is to give ''good'' luck to humans...
** Kijin Seija, BigBad of ''Double Dealing Character'', tried to cause a revolution, overthrow the society which had given the strong free reign to opress the weak and cause a societal upheaval which would allow the weak to rule over the strong instead. What drives her in her quest towards this ambitious, visionary goal? While she, herself, claims it's revenge for years of opression, the truth is that she, as an [[{{Youkai}} amanojaku]] with [[InterfaceScrew the power to turn anything upside-down]] and [[CommanderContrarian the personality]] [[PersonalityPowers to match]], simply felt like turning the world around her on its head. No matter what the results or consequences of such an act would be, just the act of doing it was her motivation.
* The skull kids from ''Franchise/TheLegendOfZelda'' commonly possess this kind of personality. The one in ''VideoGame/TheLegendOfZeldaMajorasMask'' is said to have possessed such a personality prior to finding the titular mask, [[spoiler:who also may have appeared in ''VideoGame/TheLegendOfZeldaOcarinaOfTime'', as implied in the game's ending]]. ''VideoGame/TheLegendOfZeldaTwilightPrincess'' also has a similar-minded skull kid, pulling pranks on Link while he's searching for the Master Sword.
* While usually more an IdiotHero or simple {{Cloudcuckoolander}}, ''VideoGame/CrashTagTeamRacing'' placed Franchise/CrashBandicoot as a rather conventional version of the trope for numerous easter egg [=FMVs=], harrassing Park Drones with endless pranks and AmusingInjuries.

* Bun-Bun from ''Webcomic/SluggyFreelance'' can often be like this. Oh, he'll usually ''claim'' that the people he torments did something to piss him off, but for Bun-Bun sometimes just existing in the same room as him is enough to do that.
* In ''Webcomic/MenInHats'', Aram seems to love [[http://www.meninhats.com/d/20021103.html setting his friends on fire]] or [[http://www.meninhats.com/d/20020823.html tossing scorpions on their faces]] for no better reason than that he grows bored easily.
* The Black Hat Guy of ''Webcomic/{{xkcd}}'', being based on the aforementioned Aram, also fits this trope. Unless WordOfGod says so, Black Hat Guy was probably based around the old black-hat/white-hat notion of hackers. Black-hats (as in the bad guys from cowboy movies) were the ones that hack maliciously; white-hats are out to test security systems (and occasionally rob the rich to give to the poor).
* ''Webcomic/ElijahAndAzuu'' has Fraja's Mom, who has actively antagonized every character she's interacted with at least once simply for her own amusement. She actually helps her son get through a romantic crisis by helping him realize that, as a demon, being impulsive and doing whatever you want is part of life.
** The romantic crisis only came about because ''she herself seduced her son's boyfriend''.
* In ''Webcomic/{{Freefall}}'', Sam Starfall is all about pranking and generally causing trouble for others, though none of his plans have involved the intent to cause real harm.
* In ''Webcomic/{{Sinfest}}'', this is how [[http://www.sinfest.net/archive_page.php?comicID=2819 Ezekiel and Ariel]] act when around {{Satan}}. Part of their job appears to be "annoy the Devil as much as possible so he'll be [[http://www.sinfest.net/archive_page.php?comicID=871 too distracted]] to corrupt mortal humans". Their favorite way to do this is to [[http://www.sinfest.net/archive_page.php?comicID=240 dress up as Jehova's Witnesses and ring his doorbell]].
* [[EnfantTerrible Tia]] [[JerkassGenie Darkness]] fills this role in ''WebComic/EerieCuties'', both [[ItAmusedMe for the lulz]] and [[NecessarilyEvil in order to sustain her existence.]]
** In her very first appearance, when Laura demanded bigger boobs, Tia responded by taking what Laura had and gave it to her best friend Cessily, [[http://www.eeriecuties.com/strips-ec/finders_keepers leaving Laura flat as a pancake.]] Then used the resulting catfight [[EmotionEater to feed.]]
** On another occasion, [[http://www.eeriecuties.com/strips-ec/in_your_dreams she cast a spell on Blair]] so others wouldn't look down on him. Then sat back and enjoyed the chaos [[UnwittingInstigatorOfDoom as Blair unwittingly shrank each of the guests]] at Nina's birthday party, until it was time to round up all her victims. Except she got so caught up in [[Funny/EerieCuties gloating about it]], that [[HoistByHisOwnPetard she accidentally picked up Blair.]] [[http://www.eeriecuties.com/strips-ec/i_am_not_a_surper Whoops.]]

* Fegelein from the WebVideo/HitlerRants parodies. [[http://www.youtube.com/watch?v=aataaE7wi2U "FEGELEIN! FEGELEIN! FEGELEIN!]]
** A bunch of other historical figures and fictional characters were also depicted as Screwy Squirrels in the Downfall parodies, like Mikhail Tukhachevsky, Lt. Werner from ''Film/DasBoot'', and Felicity Merriman from the ''[[Literature/AmericanGirlsCollection American Girl]]'' series.
* Tom Foolery of the ''Roleplay/GlobalGuardiansPBEMUniverse'' is a psychotic, sadistic clown who enjoys messing with people just to mess with them. Add in his scary makeup, his spine-chilling laugh, his weaponized toys, and an urge to see the whole world go down in flames, and you have a really sick Screwy Squirrel. But then, he is the setting's CaptainErsatz of SelfDemonstrating/TheJoker.

[[folder:Western Animation]]
* The earliest incarnations of ''WesternAnimation/LooneyTunes'' characters WesternAnimation/DaffyDuck and WesternAnimation/BugsBunny were "screw balls", a character type that, along with Porky Pig's [[TheEveryman everyman]], put Warner Bros. animation on the map.
** Before Bugs turned into an agent of [[TricksterArchetype righteous reprisal]], his personality largely depended on his adversary's intelligence: when facing Elmer Fudd or Yosemite Sam styled dumbasses, Bugs could only be a screwball tormentor; paired with certain gremlins or tortoises of equal wiles, however, Bugs was the ''tormented''.
** Daffy, who ''became'' a star by stealing the show, used screwiness to grab attention, and, in fact, may have been the first recurring example of this type of character; as various writers and directors learned, however, watching a screwball get his just desserts could be just as funny. A decades-long process of {{Flanderization}} turned him into the greedy, egotistical, self-righteous {{Jerkass}} we know today.
** Foghorn Leghorn was an interesting take on the ScrewySquirrel: in his cartoons, clueless outsiders would be drawn into an ongoing prank war between Foggy and Barnyard Dog; as such, both characters, while low-key, were relentless tormentors with no stated motivation.
** Sylvester the Cat, usually a hapless ButtMonkey to such characters as Tweety, was utilized as a "screwball" type to good effect in ''Back Alley Op-roar'', in which he drives a sleepy Elmer Fudd to distraction with his late-night singing. ''Kitty Kornered'' similarly played a prototype Sylvester (and three similar cats) as zany hecklers against Porky Pig.
*** Sylvester himself also fell victim to Screwy Squirrels on a few odd occasions (eg. ''WesternAnimation/CannedFeud'' and ''Scaredy Cat''). Granted since most of his tormentors were mice, we were possibly meant to interpret some OffscreenVillainy on Sylvester's part, after all CatsAreMean, but based on the short alone he played an unprovoked victim rather straight.
** The Road Runner is an odd example. While he does occasionally tease the Coyote who's trying to catch him, he very rarely has to actually ''do'' anything to thwart him. He'll just keep running around and, wherever he goes, the laws of physics will re-write themselves [[CosmicPlaything so the Coyote gets tormented]].
** In 1941, Tex Avery directed ''The Crackpot Quail'', the title character of which bore a ''very'' strong resemblance to his early Bugs Bunny. Crackpot was paired up with Willoughby the Dog, who had previously tangled with Bugs in Avery's ''The Heckling Hare''; he had a voice that sounded a bit like Bugs'; he even addressed Willoughby repeatedly as "Doc"!
** Other examples of this type in the WesternAnimation/LooneyTunes world: Charlie Dog, the Goofy Gophers, the mice Hubie and Bertie, and the Do-Do in ''Porky in Wackyland''.
*** Charlie Dog may also count as a somewhat twisted LoveableRogue, in that his antagonism was usually motivated by a profit of some kind, usually a [[TheThingThatWouldNotLeave roof over his head]]. This also applies to Hubie and Bertie and (occasionally) Daffy. That said, it's not as if they weren't shown to take sadistic enjoyment in driving their foils crazy a lot of times.
** In the classic short ''WesternAnimation/DuckAmuck'', it's the ''artist'' [[spoiler: (who is none other than Bugs Bunny)]] who plays the ScrewySquirrel. [[spoiler: Bugs got his comeuppance in ''Rabbit Rampage'', when the artist was Elmer Fudd.]]
* WesternAnimation/WoodyWoodpecker, whose merciless, skull-splitting cackle begged for comeuppance [[KarmaHoudini he seldom received]], is a good example of why Screwy Squirrels get toned down. By the '50s the character was considerably more laid-back.
* Although usually depicted as personable, DonaldDuck's famous temper is usually catalyzed by {{Screwy Squirrel}}s, most often Chip 'n' Dale.
** Huey, Dewey, and Louie actually debuted as this type of character in the 1938 short ''[[WesternAnimation/ClassicDisneyShorts Donald's Nephews]]''. For most later instances, however, it was actually Donald who started the fights, and they retaliated with some DisproportionateRetribution. Chip 'n' Dale were also similarly retaliators or {{Loveable Rogue}}s a lot of occasions. In contrast, the little orphans common in the WesternAnimation/ClassicDisneyShorts were ''always'' Screwy Squirrels against Donald, and sometimes Mickey had to suffer as well.
** Contrary to popular belief, it was Chip and Dale, not DonaldDuck who usually made the first attack. A lot of times it was merely their curiosity or hunger that grated on Donald's nerves, and led him to [[DisproportionateRetribution respond disproportionately]], after that [[EscalatingWar it was free game]]. They seemed to play the role more consistently against Pluto.
** Ironically, Donald himself played this role in ''Disney/TheBandConcert'', as he annoyed Mickey by continually turning his band's performance of the William Tell Overture into "Turkey in the Straw" [[HammerSpace with an endless supply of flutes]].
** In the early shorts Goofy can be as much of a victim of Screw Squirrel-types, due to his simple nature.
* Possibly a reference to the former character, this was the profession of the fictional retired cartoon "[[AnimatedActors actress]]" Slappy Squirrel on ''WesternAnimation/{{Animaniacs}}''. Slappy occasionally followed later [[CensorshipBureau laws]] regarding violent retribution, but always favored [[DisproportionateRetribution overkill]] and knew that her enemies were harmless. An obvious subversion, Slappy rarely excused her actions and frequently commented that modern cartoons take themselves too seriously.
** The most epic demonstration of this is when she tried to throw away a can of soda into a neighbor's trash can. Said neighbor asked Slappy to remove said can and place it in her own trash can, about five feet away. Said neighbor insists, and gets on Slappy's nerves. After clarifying that the neighbor did indeed want Slappy to remove the can she just discarded and place it in her own trash can, the neighbor asked, "Do you have a problem with that?" Slappy replies with "No, but you do." The rest of the episode is Slappy annoying her by using it, and eventually getting back at said neighbor because she ''kept throwing the can back at her'' (aiming for the head) by driving her completely and totally insane over the course of several months, until she gets rendered insane to the point that she believed the can was her baby.
** The Warners were a less-lampshaded but more prominent example. They typically act as hyperactive ConstantlyCurious children who ask questions, glomp and kiss every HelloNurse in sight, and perform gags whenever it strikes them, But otherwise, they're generally harmless until someone acts like a real JerkAss, at which point they label him their "Special Friend", and turn into Karmic Tricksters. However this has backfired at least once, such as how Mr. Director (a Creator/JerryLewis {{Expy}}) got a kick out of the very things that annoyed most people, and they didn't know how to react.
*** One episode depicted them being forced to contend with an overly nice Maria Von Trapp-type character. They realized that they couldn't justify tormenting her when she hadn't been cruel to them like most of their foes, making them more Bugs Bunnies than Screwy Squirrels. Their solution was to summon Slappy, who had no problem with violently dealing with ''anyone''.
*** In another episode they tormented a television anchorman who refused to tip them for delivering his food. The episode established the anchorman as a supreme {{Jerkass}} before the Warners appeared… but he only didn't tip the Warners because they arrived late, got the order wrong, and then ate the food anyway. It came across as LaserGuidedKarma (because he was cruel to his coworkers) but technically he didn't do anything to or in sight of the ''Warners'' themselves to deserve becoming their target.
*** In instances where they ARE true screwy squirrels, when the victim retaliates, the Warners usually realize they deserved it and leave it as is. Such as when they sang the "International Friendship Song" with an obese chef and eventually began to make fun of his weight (which he still took in good humour), but when they began taking his clothes away he gave them the literal boot, the episode ended there.
** Slappy probably gets away with it because [[ScrewPolitenessImASenior she's at Social Security age]].
*** Sometimes we see clips of her old cartoons. Aside from being a sprightly young [[ArtisticAge probably twenty-something]], the only real difference is that she's ''cheery'' about it.
* Quite a few of the early ''WesternAnimation/TomAndJerry'' shorts portray have Jerry going after Tom with little to no reason, but most of the time Tom is allowed to have the last laugh. Similarly there were a lot of times Tom was less intent on catching Jerry and [[ForTheLulz just tormenting him for kicks]].
** [[DependingOnTheWriter Until Chuck Jones came anyway.]]
* One of these turned up on ''WesternAnimation/CloneHigh''. "Try and catch me, [[ThisIsForEmphasisBitch bitch!]]"
* [[WesternAnimation/TheSimpsons Itchy and Scratchy]]. The entirety of the Simpsons' [[ShowWithinAShow show within a show within a show's]] purpose was to take this trope to the nth+ 1 degree, where Itchy is a violently psychopathic mouse that revels in repeatedly murdering Scratchy the cat in unbelievably graphic and gory ways. Interestingly, the supposed wrongs that Itchy is paying back are never shown or implied in the slightest. Itchy is merely portrayed as being an unrepentant psycho.
** Likewise, virtually all of the ''Simpsons'' characters react to Itchy's horrific cartoon sadism, by screaming with laughter.
--> '''Homer''': Itchy's a ''jerk!''
--> '''Bart''': *''Laughs''* [[ComedicSociopathy Yeah]]...
* The Aracuan Bird first introduced in ''Disney/TheThreeCaballeros'' seems to be like this. It steals José's cigar while he's still using it, and then later draws false train tracks that cause all the individual cars of a train to separate. When it shows up again in the Disney/MelodyTime short ''Blame it on the Samba'', it cheers up an incredibly depressed Donald and José, apparently just so that they'll be in a better mood for messing around with them. It also stars in a WesternAnimation/{{Classic Disney Short|s}}, a [[RecycledScript similar]] ''WesternAnimation/MickeyMouseWorks'' sketch and stars in an episode of ''WesternAnimation/HouseOfMouse'' where it is torments Donald in various ways in all three.
* Digeri Dingo from ''WesternAnimation/TazMania'' was a combination of this, DeadpanSnarker, FourthWallObserver and TooCleverByHalf.
* Sledgehammer O'Possum from ''WesternAnimation/WhatACartoonShow'' really pushes the envelope of this trope, violently and repeatedly attacking victims who not only didn't cross him, but who [[http://www.youtube.com/watch?v=FBWSpNzc0cA amiably shared lunch with him]].
* Eric Cartman of ''WesternAnimation/SouthPark'' parodies this character type when the gang encounters Osama Bin Laden, and Cartman becomes a ScrewySquirrel cartoon-character while attacking him.
* [[http://www.youtube.com/watch?v=KCH7JjQC4Rc The bird]] in ''The Dirdy Bird''.
* The three cockroaches in ''OggyAndTheCockroaches''
* The three rodents in ''WesternAnimation/BigBuckBunny'', the most virulent of them is a squirrel.
* The WesternAnimation/TeenTitansGo episode "Squash and Stretch" is about the Titans trying various ways to get their bowl of nuts back from one of these.
* ''Disney/{{Pocahontas}}'': Meeko the raccoon repeatedly steals food from anyone at any opportunity, although the hapless victim is generally Percy. It's gotten so bad that Percy is never shown eating more than a bite of food on-screen.
* The Red Guy With No Pants from ''WesternAnimation/CowAndChicken'' and ''WesternAnimation/IAmWeasel'' in his less villainous moments.
* Mr. Mxyzptlk, whenever he showed up on ''WesternAnimation/SupermanTheAnimatedSeries.'' Slightly inverted when he ends up effortlessly tricked into banishing himself by Superman; in that case the Screwball archetype is being tricked, but just to keep him out of the strait-laced hero's hair. Supes does briefly get to be a SmugSuper when he finally banishes Mxyzptlk once and for all.
* This seems to be The Monarch's modus operandi in regards to "arching" Dr. Venture in ''WesternAnimation/TheVentureBros'': to be Venture's ArchNemesis and basically just screw with his life as much as possible. In episodes where he's actually out for blood (and ''not'' targeting Dr. Venture), he's [[NotSoHarmlessVillain scarily competent]].
* Creator/{{Terrytoons}} had WesternAnimation/HeckleAndJeckle, two mischievous magpies who caused trouble as often as they [[GuileHero put a stop to it]]. Also, the Dingbat (their expy of Warner Bros.' Dodo) from ''Gandy in Dingbat Land''.
* Circe in ''WesternAnimation/JusticeLeague''. After being released from Tartarus she decides to humiliate an old enemy by turning her daughter into a pig... And then going clubbing. In the end, she voluntarily ends the curse [[spoiler:in return for having Batman sing in public.]]
* Beneath the intimidating demeanor, Lord Dominator from ''WesternAnimation/WanderOverYonder'' is [[NotSoAboveItAll a bratty, slightly-goofy]] [[SamusIsAGirl young woman]] who likes to screw with people and is in on the whole "Galactic Villain Leaderboard" thing because [[ForTheEvulz mayhem and wanton destruction are her idea of fun]]. WordOfGod [[http://suspendersofdisbelief.tumblr.com/post/132250018611/for-some-reason-i-get-a-bit-of-a-bugs-bunny-vibe explicitly says]] she's the Screwy Squirrel to Wander's [[KarmicTrickster Bugs Bunny]].
* While [[Franchise/AlvinAndTheChipmunks the regular chipmunks]] [[AvertedTrope averts this completely]], the DirectToVideo movie WesternAnimation/AlvinAndTheChipmunksMeetFrankenstein [[ParodiedTrope parodies this trope]] when Alvin [[spoiler: drinks a potion from Dr. Frankenstein that turns him into a [[{{Expy}} Warner Bros. esque]] screwball character.]]
