->''There's a gentleman that's going 'round\\
Turning the joint upside down\\
Stool pigeon - ha-cha-cha-cha''
-->-- '''Kid Creole and the Coconuts''', "Stool Pigeon"

The tattletale. The blabbermouth. The squealer. That no-good snitch! You can't go through life without having the misfortune of coming across someone who's willing to rat you out and get you in trouble.

However, the motivations of the snitch and how they're regarded in a story can vary wildly. Snitches have the reputation of being [[DirtyCoward cowardly weasels]], but there are times where a snitch can be responsible or heroic. Due to the sheer prevalence of this trope, there are several important variations:

'''Petty Patty/Peter:''' A character that's [[GreenEyedMonster jealous]] of the main character or has a [[EvilIsPetty petty reason]] to dislike them, and thus relishes the chance to get them in trouble. You can usually spot them [[SmugSnake smiling smugly]] as the main character is chastised for whatever they did. Naturally, they're going to [[LaserGuidedKarma get some payback]].

'''Concerned Claire/Corey:''' A character that turns in a friend or associate out of genuine concern for their well-being. Maybe their friend is sliding towards becoming a WellIntentionedExtremist, maybe they're compromising their cause, or maybe they're going to land themselves in jail ...[[DeathSeeker or worse]]. This character is willing to nobly [[WhatWereYouThinking take any hostility from their friend]], because they'd rather [[ForYourOwnGood see them alive and safe than continue what they were doing]]. Whether their concern is responsible or misguided can vary.

'''Whistleblower Wilma/Wilson:''' A character who sees a villain - [[WhatTheHellHero or even a hero]] - breaking the rules and turns them in because of [[TheFettered their own moral conscience]]. The most heroic of all snitches, many whistleblowers risk their friendships, careers, or even their lives to tell the truth.

'''Disgruntled Daria/Davey:''' A character that [[OnlySaneMan dutifully gives information to their superiors]] but is then unsatisfied with how they deal with it. If they won't listen to her, then she'll find someone who will! This kind of snitch can vary wildly; sometimes the [[HeadInTheSandManagement authorities refuse to listen]], so they secretly tell someone else who will take action. However, sometimes [[ReasonableAuthorityFigure the authorities]] are just acting in a way she doesn't like and thus is going to [[TheyCalledMeMad force their hand]]. This latter variation can be considered treason and can cause [[AHouseDivided internal strife]].

'''Betrayer Belinda/Barry:''' A character that [[ChronicBackstabbingDisorder sells out their own friends]] to save his own skin. Maybe they've gotten caught and [[PleaBargain offered a plea deal]], maybe the authorities are offering incentives, or maybe they're [[{{Jerkass}} just jerks]]. Either way, this character can end up [[CementShoes in a lot of trouble]] if his friends find out what he did ...

'''Snobby Sara/Simon:''' A character that turns in any other character, no matter what reasons they had for what they did. They broke the rules, so those little punks have to suffer the consequences! This character doesn't care about justice or rules as much as they [[{{Pride}} enjoy feeling smug and superior to others]].

'''Obnoxious Olivia/Oscar:''' A kid character that tattles on someone else for ... well, the thousands of reasons why kids like getting people in trouble. Usually played for laughs, but can sometimes can be taken more seriously, especially if the kid is a young whistleblower or is called a liar.

'''Innocent Ingrid/Isaac''': A character who, along with other characters, has been involved in some activities that have gone rapidly downhill, and turns them in because of this. Maybe they never wanted to do anything bad but suddenly found themself caught up with people prepared and willing to do so, maybe their co-conspirators began doing things that they cannot stand, or maybe they honestly didn't know that their friends or co-workers were doing anything wrong and upon finding out, decide to turn them in.

'''Drug Debbie/Doug''': A character who ends up blabbing about activities to another person without realizing it because they were under the influence of drugs or [[InVinoVeritas alcohol]]. Also a TruthInTelevision, as drugged people or drunk people often blab the truth at the most inappropriate times due to their inhibitions being loosened. Can sometimes fall under Lacerated Larry if the person was drugged as part of an interrogation.

'''Obedient Olga/Obadiah''': A character who spills the beans because he or she believes this is what a good citizen ought to do, [[NothingPersonal without any personal grudges or strained relationships]]. Because they hold no grudges, such a person simply blabs and immediately moves on. They may believe [[BlindObedience obedience to authority to be a virtue]] and any defiance of it is inherently wrong. They are neither TheMole nor a spy. They never had anything to do with whomever they ratted out in the first place, but simply discovered them and reported them the same way one might report a suspicious package to the police.

and, more sympathetically

'''Lacerated Lacey/Larry:''' A character that was simply [[JackBauerInterrogationTechnique interrogated]] to the point of having the information [[ColdBloodedTorture tortured out of them.]] In many cases, the person may have been an extremely loyal comrade and in normal circumstances would not have ratted out their team. But since TortureAlwaysWorks and the cold hearted villains [[WeHaveWaysOfMakingYouTalk have ways of making victims talk]], the captured member will always be left screaming in the end.

Snitches vary from GossipyHens because they're actually telling the truth and usually telling it to a recognised authority, whether it's a parent or the government. This can lead to a lot of MoralDissonance, because no matter how much of a jerk a snitch might be, the characters wouldn't have gotten in trouble if they hadn't done something snitch-worthy in the first place.

[[folder:Anime and Manga]]
* In ''Manga/{{Naruto}}'', Shizune goes to Homura and Koharu regarding Tsunade allowing Naruto to go on missions where he might encounter the Akatsuki. She's clearly a Concerned Claire over Naruto's well-being, where Tsunade is far more inclined to take it on faith that [[IdiotHero Naruto]] will make it out alright. She gradually begins to accept Tsunade's reasoning, but when she does, the elders come in to attempt to restrict Naruto's movements based on what Shizune told them, and in the anime, Tsunade gets quite upset with Shizune.
* In ''Anime/GuiltyCrown'', [[TheLancer Yahiro]] ends up selling out the protagonist to secure treatment for his [[IllBoy sick little brother.]] Especially jarring since he used to be an admired friend of [[TheHero Shu's]], who was under the impression that they had sucessfully talked over their differences. Even after Yahiro returns to being a permanent member of Shu's group, the tension created by this event remains between them for most of the series, leading to several "Silence, Traitor!" moments.
* In the ''OnePiece'' anime, one of the slaves on Tequila Wolf reports Robin to the others when being threatened with punishment, and is rewarded with a box of chocolates. She, however, is overcome with guilt, and gives it to Soran, who goes to give it to Robin.
* In Turn 19 of ''[[Anime/CodeGeass Code Geass R2]]'', [[spoiler:after Schneizel meets some resistance to the Black Knights in his efforts to goad the Black Knights into turning on Lelouch, Ohgi and Villetta's account of Lelouch's geass end up sealing the deal. Quite possibly a Petty Peter for Villetta, and a misguided Whistleblower Wilson for Ohgi, considering [[QuoteMine some of]] [[FalseReassurance the evidence]]]].
* In the manga version of ''Anime/NeonGenesisEvangelion'', Kaji was a Betrayer Barry when he was a kid. He and his friends were stealing food and supplies from a military base. Kaji was caught, and gave up his friends to the soldiers to keep from being killed. The soldiers killed his friends, and he's been haunted by SurvivorGuilt ever since.
* In ''Manga/{{Bokurano}}'', Tamaki "Komo" Komoda is an Innocent Ingrid, since she is the one who tells the authorities about the kids piloting Zearth once it becomes clear what they've gotten involved in. In the manga, she goes to her father, who is an admiral, after a few battles have taken place. In the anime, while the group is being questioned by the police after the second battle, she tells them that they were piloting the robot.

* In ''ComicBook/IdentityCrisis'', Wally West averts this trope, even though he'd fall squarely into the Whistleblower Wilson category, when he decides not to [[spoiler: tell Superman and Batman that a group of Justice League members have been wiping supervillains' memories via Zatanna to protect their secret identities, even when he learns they went so far as to effectively lobotomize Dr. Light and, when Batman found out and objected, mind-wiped him as well]].
* [[spoiler:Becky]] of the ''ComicBook/SinCity'' story ''The Big Fat Kill'' falls squarely into Betrayer Belinda territory. Her reason for selling out Gail and the other girls of Old Town was that [[spoiler:Manute and the mob offered her a way out of being a prostitute, something the girls of Old Town never did. It didn't help that she wasn't willing to let the girls of Old Town protect her mother, [[DontTellMama who she kept her life as a prostitute a secret from]]]].
* One of the things that keep the NaughtyIsGood characters in ''Comicbook/TheBeano'' looking like the good guys is that they're contrasted with characters like Cuthbert Cringeworthy and Walter, who are a combination of Petty Peter, Snobby Simon and Obnoxious Oliver.
* In ''ComicBook/PaperinikNewAdventures'' retired general Wisecube becomes a Disgruntled Davey in his last appearance, deciding that if the US government and army won't reveal to the public about the Evronian threat then he'll do it to force them to act. He's shown as a WellIntentionedExtremist for this, as he apparently doesn't get that doing this would cause mass panic and make defence against the Evronians even more difficult-or that he was forced to retire because his assault to the main Evronian spore nest in Africa was effectively an act of war against Kenya and completely unauthorized by the government or the Pentagon.

[[folder:Fan Fiction]]
* Bolt Buck is the Betrayer Barry type in ''FanFic/CapeAndCowl''; Bolt Buck tells Snow Storm who her brother's other murderers are and where they are after he's put into the hospital by her attacking him the night before.

[[folder:Films -- Animated]]
* In ''WesternAnimation/ToyStory3'', Chatter Phone was the Lacerated Larry type: he ended up confessing to Lotso and his minions about Woody and the others escaping from Sunnyside from what was implied to be torture.

[[folder:Films -- Live-Action]]
* ''Film/TheInsider'' is all about this.
* In ''Film/{{Bullitt}}'', Johnny Ross, a Chicago mobster who agrees to testify against the Mafia. Naturally, the Mafia wants him dead for this--and for the money Johnny stole from them.
* ''Film/InsideMan'': [[spoiler: The reason for the owner of the bank not wanting his diamonds to be discovered, and the reason why the protagonist gets away with it.]].
* The film version of ''Film/HarryPotterAndTheOrderOfThePhoenix'' made Cho Chang into a Drug Debbie. Dumbledore's Army was initially angered at her betrayal, but then it is revealed that the only reason she squealed was because Umbridge fed her a drink laced with [[TruthSerums Veritaserum]], thus literally leaving Cho with no choice but to spit out the existence of Dumbledore's Army.
* ''Film/{{Brute Force|1947}}'': Wilson gets killed for being a snitch, although he's not a ''Wilson'', but a ''Barry'' type of stoolie.
* The admiral in the 2009 ''Film/StarTrek'' movie also ended up a squealer to the Romulans, specifically as a Lacerated Larry, because after he left the ship, they interrogated him and implanted a bug into his system that forces him to reveal everything he knows about Starfleet Academy.
* Magneto was a Lacerated Larry in the beginning of ''Film/X2XMenUnited'': It is strongly implied that Stryker had arrived at Magneto's cell beforehand and injected him with the same brainwashing serum from his son to get him to lure Professor X into his prison so X could be captured.
* Detective Ed Exley in ''Film/LAConfidential'' is a mixture between being Disgruntled and a Whistleblower. In the former, Exley ends up ratting out his fellow officers to their Captain after he witness them conduct police brutality on captured crooks. Naturally [[TruthInTelevision this makes him unpopular with the other officers.]] Later in the movie, [[spoiler: he ends up going after his Captain as well after learning how corrupt he is.]]
* ''Film/SchoolTies'': [[spoiler: Rip Van Kelt becomes a Whistleblower Wilson, unwilling to let David Greene take the blame for cheating on a test in place of the true culprit.]]
* Kent from ''Film/TheBigHouse'' is a Betrayer Barry type, a DirtyCoward who rats out his friends, informing on an escape attempt in hopes of lightening his sentence.
* Peter Ames, from the film ''Film/TheMadMissManton'', is always willing to rat Melsa and her friends out: first, when he finds out Melsa is withholding evidence, and then, when he finds out they’re keeping Frances Glesk, a suspect, with them.
* In ''Film/WhereTheSidewalkEnds'', one of Scalise's boys has been got by the police and he tattles on Scalise's secret hideaway, inadvertently saving Mark from being killed by them.

* In ''Literature/ABrothersPrice'', when Corelle is found out to have [[spoiler: has sex with Balin Brindle]], she points at Jerin and tells Eldest that [[spoiler: Jerin was seduced by Ren.]] It doesn't work the way she wants to, though.
* In ''Literature/TheBerenstainBears and the Scandal Sheet'', the members of the student underground newspaper, including Brother, get exposed and in trouble for making a false statement about a teacher dating someone when Brother tells his sibling about it, who passes the word to Mama who then informs the authorities. This is a case of a Concerned Claire that actually turned out for the better, as with the exposure, the real student newspaper was able to be reformed, making the student underground unnecessary.
* Melvin Sneedley from the ''Literature/CaptainUnderpants'' books is a Snobby Simon, a boot-licking nerd who frequently rats out George and Harold whenever they make mischief, just to feed his ego about being the "perfect student".
* [[spoiler:Stelli]], in Paula Volsky's novel ''Illusion'', is somewhere between a Petty Patty and a Disgruntled Daria: She blames SpoiledSweet heroine Eliste [[spoiler:(for whom she used to work as a maid)]]for [[spoiler:being unable to save her fiancé's life]] (and in all fairness, Eliste ''tried'') and sells the noblewoman out to the revolution. [[spoiler:Eliste gets away.]]
* [[spoiler:Tuller]], in ''[[Literature/TheColSecTrilogy ColSec Rebellion]]'', sells out the main characters to the cops, supposedly to make them leave his gang alone, but it's made fairly clear that he mainly just did it to be a jerk. The rest of the gang are dubious about this to begin with[[spoiler:...and when they find out that the cops have no intention of keeping their end of the bargain, they [[KarmicDeath turn on Tuller]] and [[DeathOfAThousandCuts knife him]]]].
* The book version of ''Literature/HarryPotterAndTheOrderOfThePhoenix'' has Marietta Edgecombe snitch on Dumbledore's Army instead of Cho Chang. She's portrayed as a Betrayer Barry and is left with the word "Sneak" written across her face in boils because Hermione hexed the club's roster sheet.
* Sloan from [[Literature/InheritanceCycle the Inheritance Cycle]] pulls the Petty Peter version, twice. Though the second time could be considered to have gotten him RewardedAsATraitorDeserves.
* Nelthilta, the silly young Efrafan doe from ''Literature/WatershipDown'', is a variant of the Lacerated Lacey; she's overconfident and gives one too many obvious hints about the upcoming escape plan to the Efrafan officers. Realizing that something is amiss the officers imprison her and torture her into spilling the beans completely.
* In ''A Stainless Steel Rat is Born'', Jim, remembering how he decided to pursue a criminal career, recalls a childhood episode in which he framed an Obnoxious Oscar schoolmate for shoplifting. This lad was known to the student body as Smelly, and tattled on other children for the simple pleasure of it.
* The backstory in Stephen Goldin's ''A World Called Solitude'' reveals [[spoiler:Reva Aaland]] to have been a Lacerated Lacey. However, [[spoiler:the estranged ex whom she was coerced into smearing]] [[UnreliableNarrator vacillates]] between understanding as much and viewing her as a Betrayer Belinda.

[[folder:Live-Action TV]]
* Jayne of the ''Series/{{Firefly}}'' episode "Ariel" tried to turn in the Tams to the Alliance during the hospital heist due to him generally resenting the Tams and wanting them both off the ship for a variety of reasons, and due to River recently slashing him with a butcher knife and his concern about her doing it to anyone else. The reward money that the Alliance were offering wasn't a bad incentive either. Jayne was somewhere between Petty Peter and Betrayer Barry, but after Jayne got betrayed himself and arrested right along with them, he decided to get both Simon and River out. He still had to face [[ThrownOutTheAirlock the airlock]] and a [[PapaWolf very pissed off Mal]] because of what he did though.
* In a VerySpecialEpisode of ''Series/TheBradyBunch'' Cindy learns not to tattle - then is [[BrokenAesop asked to tattle]] to find a valuable certificate.
* ''Series/{{Monk}}'':
** The culprit in the episode "Mr. Monk and Mrs. Monk's" main motivation in trying to intercept various documents and tapes that detailed journalistic work that Trudy Monk and Janice worked on was because [[spoiler:one of the tapes contained evidence that he was the person inside the dock union who was involved in ousting the former president from power due to corruption charges, and it is heavily implied that had his fellow union workers discovered his involvement, he'd be in deep trouble with his "friends."]]
** "Mr. Monk Goes to the Dentist" had a Drug Doug type from the murder [[AssholeVictim "victim"]] of the week: The victim (an ex-cop who went renegade and started robbing armored trucks) is Denny Jardeen, who ends up having to go to Dr. Oliver Bloom for a chipped tooth that he gets in a scuffle with an armored car driver (in the resulting scuffle, both drivers were shot dead). As an ex-cop, Dr. Bloom is on Jardeen's medical plan. While going through the routine anesthesia, Jardeen, evidently under the anesthesia's influence, blabs to Dr. Bloom about the heist as well as the hiding place for the money, to which Dr. Bloom and hi assistant Teri steal the money. Unfortunately, Jardeen, either from lingering memories of what happened, or having put two-and-two together, confronts them in their office while they are working on a patient, and he is killed when Teri strikes him with the roots of a giant plastic tooth after a fight. Said patient Dr. Bloom is working on happens to be Randy, who tries to convince Stottlemeyer and Monk and anyone else around him that he saw the murder (Dr. Bloom cleans up the office after the fight and dumps the body as well).
* In "The Telling", a third season episode of ''Series/TheMiddle'', we learn that Frankie has been rewarding Brick for years with candy cigarettes for informing on his older siblings.
* ''Series/{{Scandal}}'': Justice Verna Thornton becomes a Betrayer Belinda in "Blown Away". Vice President Sally Langston wants Verna out of her Supreme Court seat, while Verna has only a few months to live before she dies of cancer. So Verna offers her a choice: either take her resignation or take the paper revealing the identity of the President's shooter. Sally takes the identity revealing paper and Huck is arrested. Verna had put two and two together to figure out that Huck supposedly shot the President. Huck didn't do it, and Verna doesn't know that. So it's ambiguous if she was doing this to selfishly keep a job she only gets to have for a few months or if she did it because it's her duty to take down whoever shoots the President.
* In the ''Series/{{Supernatural}}'' episode [[Recap/SupernaturalS09E02DevilMayCare "Devil May Care" (S09, Ep02)]], Crowley gives up the names of two demons and the Winchesters expect to give the names of the rest of the demons on earth.
* In ''Series/{{Gotham}}'', Gertrud Kapelput (the Penguin's mother) is of the Petty Patty variety, selling out the father of a classmate she had a problem with.
* In the ''Series/MurdochMysteries'' episode "Bl--dy H-ll", Brakenreid becomes a Whistleblower Wilson during his TenMinuteRetirement at City Records, discovering evidence of a conspiracy in the city council. His boss at City Records almost coins the word:
-->'''Mr Dilbert''': I understand. You used to be a policeman. You see a problem and you want to ... blow your whistle. But it is not our job to blow whistles.
-->'''Brakenreid''': If we don't, who will?
* A major plot point in the ''Series/MagnumPI'' episode "Past Tense", where one of Magnum's ex-colleagues from UsefulNotes/TheVietnamWar is broken out of prison.

* [[Literature/TheBible Judas]]. Petty Peter appears to be the closest approximation, though [[Music/JesusChristSuperstar certain adaptations]] present him as more sympathetic.

* Lifesaver from ''VideoGame/MegaManX5'' reported to [[ReasonableAuthorityFigure Signas]] that Zero was actually getting stronger when infected with TheVirus. When Signas wisely decides not to act rashly, Lifesaver snitches to Zero's best friend X instead. The resulting misunderstanding and tension results in a battle between the two that nearly gets both friends killed.
* Sidonis from ''VideoGame/MassEffect2'' is a Betrayer Barry. Part of Archangel's squad on Omega, he was caught by the mercenary gangs and ended up betraying Archangel to save his own skin. Depending on how you deal with Garrus's mission, he'll either end up dead by Garrus's hand or he'll be given a chance to redeem himself after admitting his guilt.
* In an early Blood Elf starting quest in VideoGame/WorldOfWarcraft, the player is asked to find a book for two apprentices. When the book is drenched in water, the apprentices tell the player to take the fall for them, since the player won't be punished much. Instead, upon reaching their master, you tell him what they told you to do, and he has you [[BalefulPolymorph hit them with a rod that turns them into animals]].
* In the old ''VideoGame/SkoolDaze'' video game on the UsefulNotes/ZXSpectrum, a randomly triggered event reveals that Einstein is going to report the player. The player must prevent him from getting to the teacher or else get assigned lines; receiving 10,000 of them results in a Game Over.
* ''VideoGame/MetalGearSolid3SnakeEater'': Even though Raikov is supposed to be Volgin's gay lover, interrogating him at knifepoint will have him dish out information about some weaknesses of Volgin for Snake to exploit, such as the fact that Volgin is weak against water or that Russian Glowcaps will deflect his electric attacks.
** In ''[[VideoGame/MetalGearSolidPeaceWalker Peace Walker]]'', anyone of the FSLN who is captured by the Peace Sentinels ends up being tortured until they squealed their comrades' location from it. They end up killed later on. Chico is the only one who managed to live after breaking from it (and even then only because Big Boss rescued him before they could get the chance to execute him).
* According to Dr. 0, Dr. Borous spent high school "commie-fink tattletal[ing]" on the kids he disliked in the backstory of ''VideoGame/FalloutNewVegas: Old World Blues''.
* In ''VisualNovel/LuckyDog1'' Homer tries to persuade Gian, the player character, to become one of these as he falsely believes Gian (a member of the mafia) hates criminals due his parents being murdered and the criminal never getting caught. There's no option to become one as Gian is completely loyal to the mafia but there is an option to attack Homer, who told the guards to stay away from the room believing Gian would agree to be a rat.
* In ''VisualNovel/PhoenixWrightAceAttorneyDualDestinies'', [[spoiler:Juniper Woods]] turns out to be a justified Concerned Claire variant, as she was recruited by Professor Courte to be this to save the students at Themis Academy from giving in to the Dark Age of the Law. She obviously takes ''no'' pleasure in this role, and breaks down in tears upon believing that one of her friends might be doing something corrupt.
* [[spoiler:Hector]] from ''VideoGame/PAYDAY2'' was a Betrayer for the PAYDAY Crew. They were collaborating with the FBI to get the crew arrested, in exchange for a reduced prison sentence. Their intel had already led to the arrest of Hoxton prior to the start of the game, but the crew later broke him out and raided the FBI for info. This led the crew to the traitor's location, where they killed [[spoiler:him]], both out of revenge and to throw the FBI off their trail.

* In the ComicBook/ChickTract "The Last Generation", Bobby turns in his grandfather for being a Christian in order to get a reward. One of the Christians, Paul reveals the location of the cabin where Connie and Charles are hiding, afraid of being caught and tortured.
* ''Webcomic/BobAndGeorge'': [[http://www.bobandgeorge.com/archives/050417c X reveals that Zero was going to dump his body in the river, and gets accused of being a snitch]].
* In ''{{Webcomic/Drowtales}}'' a young Jaal'darya girl named Wa'fay [[http://www.drowtales.com/mainarchive.php?sid=8295 risks her life]] traveling through the war-torn city to inform the Sarghress clan of her mother's activities, mainly developing a parasitic flower for the [[ManipulativeBitch leader]] [[BigBad of the Nidraa'chal]], who intends to use it to force everyone to bow to her in a massive PoisonAndCureGambit. She's clearly the Whistleblower Wilma variety and her courage saves countless lives when it starts a chain of events to undermine the plan.

[[folder:Western Animation]]
* Sarah from ''WesternAnimation/EdEddNEddy'' is the Obnoxious Olivia, the Petty Patty, and the Snobby Sara depending on the episode. She is a SpoiledBrat who is favored by her mother more than [[TheUnfavorite Ed.]] She always threatens Ed to do her bidding or she'll "tell mom." It doesn't help that their mother just goes along with Sarah.
** In one episode, when Eddy leads the other kids in breaking the rules, Double-D tells everyone's parents to restore order. Unfortunately, this results in Kevin, Rolf, and Johnny to throw the Eds into a cage.
* Candace from ''WesternAnimation/PhineasAndFerb'' seems to vary between Snobby Sara, Obnoxious Oliva, Concerned Claire or Petty Patty, depending entirely on [[DependingOnTheWriter the writer]].
* ''WesternAnimation/AaahhRealMonsters'': Zimbo, he not only acts as the Snorch's Familiar, he also acts as the Gromble's personal spy who reports back any unruly behavior by the other monsters, plus he's the only one who understands the Snorch's speech clearly which he'll eagerly exploit for his personal advantage. However, being the Gromble's spy doesn't exempt Zimbo from being punished or chastised, such as when he spread rumors that Ickis was going to explode due to his spontaneous combustibility and turned him into a pariah. Or the time he stalked and harassed Ickis by pretending to be a teddy bear from an animated movie which Ickis had been traumatized by.
* Randall from ''WesternAnimation/{{Recess}}'' is The Obnoxious Oscar in spades.
** He has [[EvenEvilHasStandards reservations]], however. For one thing, he never tries to directly squeal on those who are higher up than him (such as King Bob), and gets legitimately angered at those who do end up doing something like that. In addition, in the ending of the movie ''School's Out'', Randall was noticeably disgusted with Fenwick desperately trying to avoid jail time by pinning his boss, Dr. Phillium Benedict, with the entire blame on the events of the movie, and even offering evidence for the state trial.
** In the episode where Principal Prickly is accidentally hypnotised to act like a six-year old, when TJ and his friends decide to keep it under wraps, Randall overhears them. Unlike most other times where he usually takes joy in snitching, his snitching about what happened to Prickly falls more under the Concerned Claire subtype, as he expresses genuine shock and horror and rushes to Finster to tell her of what happened.
* ''WesternAnimation/LooneyTunes'' has several cartoons that display this:
** "A Day at the Zoo": As a spot gag described in the picture above, very Snobby Simon.
** "Don't Axe Me": The Barnyard Dawg squeals on Daffy for Elmer to catch him.
** "Buccaneer Bunny": One parrot keeps telling Pirate Sam where Bugs is hiding until Bugs himself puts him out of his misery by offering him a cracker...a '''fire'''cracker.
-->'''Parrot''': Me and my big mouth.
** "Tom Turk and Daffy": Daffy squeals on the Turk because of his weakness for candied yams.
** The short "Big House Bunny" ends with prison guard Sam getting arrested for freeing convict Bugs when he's pushed to his limit. When he asks who was the stool pigeon who squealed on him, it cuts to Bugs, who [[AsideGlance looks at the camera]] and [[VisualGag starts cooing like a pigeon]].
* ''WesternAnimation/TheSimpsons'':
** Frankie the Squealer/[[{{Expy}} Jimmy the Snitch]] of Fat Tony's gang. [[MeaningfulName The name(s)]] [[ExactlyWhatItSaysOnTheTin speak for themselves.]] Frankie doesn't really fit any of the above archetypes, but rather has a compulsive urge to squeal ("It makes me feel big!").
** "Bart the Daredevil": Despite trying to convince Bart the dangers of daredevil stunts, Lance Murdock is instead impressed by Bart's interest in it, which causes Lisa to tell Homer about it, fearing that he may get hurt or die despite getting the most attention.
** "Mypods and Broomsticks": Lisa squeals on Bart after pulling a prank on Steve Mobbs and the rest of the consumers and employees.
** Martin Prince is also one when he squealed on Bart in "Bart the Genius" and on Milhouse in "Summer of 4 Ft. 2".
** The whole episode of "The Seven Beer Snitch" focuses on this trope.
** Lisa is pretty much this constantly, with many [[RecycledScript many plots throughout the seasons]] (as an example, ''Lisa Gets An F'') revolving about someone building a lie (and sometimes the plot showing that the lie is the ''better'' thing for everybody (even Lisa herself) and everybody saying so) and Lisa trying to tell the truth regardless. She ''thinks'' of herself as a Concerned Claire-type (in that she says it's the legal/moral thing to do), but what type she ''really'' is depends on the plot at hand (at least sometimes shows to be doing it out of some desire to thumb her nose up at the liar).
* ''WesternAnimation/FamilyGuy'': Brian in "Deep Throats" (he was the Petty Patty towards Adam West). And again in "Dial Meg for Murder" (he was the Concerned Corey, however).
* [[spoiler:Robin]] in WesternAnimation/BatmanBeyondReturnOfTheJoker qualifies as a Lacerated Larry. After the Joker kidnapped him, he subjected him to three weeks of shock and serum-based torture before he ends up [[spoiler:breaking from it and confessing everything he knows about Batman, including his secret identity]].
* In ''WesternAnimation/BatmanTheAnimatedSeries'', Earl Cooper was a Whistleblower William who was nearly killed by his bosses for trying to go public about a potential lethal safety defect in his company's newest model of car and was saved by Batman. He lost his job and was living on the streets when Batman saved him again... by tracking him down and hiring him to design the Batmobile.
* In an episode of ''WesternAnimation/{{Beetlejuice}}'', there was [[TheStoolPigeon a Stool Pigeon]] that was a well, a [[ExactlyWhatItSaysOnTheTin Stool Pigeon]]. His phrase of choice was "I'm Telling".
* A ''WesternAnimation/PrivateSnafu'' short has Snafu bragging about a secret that he knows but won't tell. Unfortunately, he ended up becoming exceptionally drunk, and told the nearest woman in the tavern about his secret (being on a ship and its coordinates), who also turned out to be a Nazi spy, resulting in his death and the implication that he went to hell for it. In other words, he acted as a Drug Doug on ''himself''. This cartoon can also be seen at the International Spy Museum.
* Mako in ''WesternAnimation/TheLegendOfKorra'' is a Concerned Corey in the episode "Peacekeepers", ratting Korra out to the President to prevent her from doing something completely irrational and escalating the Water Tribe's civil war.
* Dade in ''WesternAnimation/HarveyBeaks'' is a [[NervousWreck nervous wreck]] whose first instinct whenever he's in a major panic situation is to tell on grown-ups.
--> '''Fee''': Wait, who is this?
--> '''Dade''': Dade.
--> '''Fee''': Ooh, Tattle Pants!

* The ''WesternAnimation/KickButtowski'' episode "Tattler's Tale" has Miss Chicarelli acting as a mix of Snobby Sara and Obnoxious Olivia; she tattles on all the kids in the neighborhood to their parents so she can get them out of her hair for some peace and quiet.

* Siblings tend to be this. Even relatives like aunts, uncles, cousins, grandparents, etc.
* Cameras near traffic lights and roads. They tend to take photos of you going even 3 miles above the speed limit or take photos of you running the red light. The photos go to the department and you end up getting a ticket mailed to you.
* There are special statutes called "Whistleblower Laws" for Disgruntled Darias who report wrongdoing within an organization to its own internal authorities, see it not acted upon, and then take it to civil authorities (i.e. police). They are meant to protect such "whistleblowers" from retaliation. How well this actually works in practice varies widely and the bodies responsible for such laws [[ScrewTheRulesIMakeThem have a tendency to make them inapplicable to their own whistleblowers]].
* Scandals in the USA often generate whistleblowers.

** Harry Markopolos repeatedly complained to the Securities and Exchange Commission about Bernard Madoff, but the [[CluelessDetective agent assigned to the case bungled the case because he thought that Madoff was committing front-running]] and failed to consider that Madoff could be running a {{Ponzi}} scheme.
** Chelsea Manning sent documents regarding war crimes and other things to [=WikiLeaks=].

* [[HonestCorporateExecutive Michael Woodford]] was at one time the CEO of Olympus Corporation. He discovered a massive tobashi scheme (a type of accounting fraud) and tried to [[InternalReformist clean it up from the inside]], but he got fired by the [[CorruptCorporateExecutive board of directors who were committing the fraud]]. He went to the police with the details of the fraud.
* Joseph Valachi was the first [[UsefulNotes/TheMafia Mafia member]] to admit in public, on national television that ''Cosa Nostra'' is real. No one knows for sure why he decided to flip, but it's speculated that Vito Genovese, a fellow inmate (and the boss of the Genovese crime family at the time), incorrectly branded him as [[TheInformant a rat]] and gave him the kiss of death - a sign that he was to be killed. Fearing for his life, he accidentally killed a fellow inmate he mistakenly believed had been assigned to kill him, and because of the accidental murder, he faced the death penalty. Hoping to get a lesser sentence, Valachi decided to squeal on national television to the U.S. Senate Permanent Subcommittee on Investigations, headed by John [=McClellan=] in late 1963. Although his disclosures never led directly to the prosecution of many mobsters, he provided a detailed glimpse of the mob's goings-on and inner workings, aided in the solution of several unsolved murders, and named many members and the major crime families. His testimony proved to be damning for the Mafia, still reeling from the [[CriminalConvention Apalachin fiasco]], where a curious cop accidentally stumbled upon a major mob meeting. Also, law enforcement began to crack down on organized crime activities, bolstered by the passage of the Racketeer Influenced and Corrupt Organizations (RICO) Act in 1970, which allowed entire criminal gangs and their leaders to be prosecuted for all of their criminal operations instead of just going after low-level grunts, thereby crippling the Mafia by the 1990s.
