->'''Jade:''' Doesn't she know Valmont is a thief?\\
'''Tohru:''' No, and please don't tell her.
-->-- ''WesternAnimation/JackieChanAdventures''

Everyone knows that EvenBadMenLoveTheirMamas and because that's the case, a lot of bad men, whether they might be gangsters, {{Professional Killer}}s, {{Corrupt Corporate Executive}}s, [[HitmanWithAHeart Hitmen With A Heart]], [[GentlemanThief Gentleman Thieves]] or {{Anti Hero}}es in a morally questionable job will try to do their utmost to keep their mothers from knowing what it is they ''really'' do. This can extend to getting enemies to join in on TheMasquerade in order to keep her blissfully unaware.

Naturally there are many variations on this, as the character in question may be trying to keep the truth from a father, sibling, {{True Companion|s}}, etc.

Some criminals doing this often like to think of themselves as TheDutifulSon, providing for and protecting their mother or family while also keeping the knowledge of where the family's prosperity comes from secret, but their true status will depend on their other actions, as the character in question may be anything from a {{Delinquent}} to an AntiVillain. In many cases this trope is a source of {{Wangst}} or PetTheDog moments, but when the secret is sufficiently important, it can turn into PoorCommunicationKills.

Plenty of the mothers know what their sons do, but some are either [[MamaDidntRaiseNoCriminal in denial about it]] or not saying anything about it for the sake of family peace and quiet.

Often requires at least some ParentalObliviousness in order to work. Most characters that engage in this do so because they desperately crave hearing those magic words "[[SoProudOfYou I'm so proud of you]]" and don't want to make it go away.

See MamaDidntRaiseNoCriminal for when she learns the truth and struggles accepting it.



[[folder:Anime and Manga]]
* There's a variation in ''Anime/CodeGeass'', where Lelouch tries to keep his alter ego secret from his sister.
* AntiVillain variation in ''Anime/MagicalGirlLyricalNanohaAs'', where the Wolkenritter keep their gathering of Linker Cores to complete the Book of Darkness and save Hayate's life a secret from Hayate, knowing that she would not approve. She eventually finds out about what they were doing during the final battle; the Wolkenritter apologize and Hayate forgives them.
* ''Manga/DeathNote'' has Light Yagami, TheProtagonist of the series, who tries not to let his parents and sister know that he is Kira... though not for emotional reasons so much as practical ones; his father is the chief of police.
* In ''Anime/DigimonTamers'', Rika tries to keep Renamon a secret from her mother, [[YouWouldntBelieveMeIfIToldYou as she thinks she wouldn't understand]]. She said this phrase to her grandmother. Eventually, her mother ''does'' find out about Renamon and seems to be fine with that.
* ''Manga/{{Onidere}}'': Saya wants to keep her delinquent status a secret from her little sister.
* In an episode of ''Anime/{{Pokemon}}'', James convinces Jessie, Meowth, Ash, Brock, May, and Max not to let his grandparents know he's a member of Team Rocket because it would break their hearts. Despite Jessie and Meowth going back on it and trying to steal the grandparents' Pokemon, he manages to keep up the charade... and then tells them everything in the end. As he waves goodbye, his grandparents discuss what a wonderful boy he is and even if he is a member of Team Rocket, whatever that is, they're still proud of him.
* A major part of the plot in ''LightNovel/HaruhiSuzumiya'' is the other characters trying to keep the easily-bored titular character [[LockedOutOfTheLoop ignorant of the fact that she's actually a]] RealityWarper that can, on a simple whim, rewrite, destroy and/or replace the whole universe with an all new one that's more to her own liking. Some villains related to the [[SufficientlyAdvancedAlien Data Overmind]] try to provoke a reaction like this from her by, for example, attempting to harm her TrueCompanions... which is the kind of bull that eventually leads [[TheHero Kyon]] to outright weaponize this trope by threatening the D.O. to reveal "[[TrustPassword John Smith]]" to Haruhi, the end result which would doubtlessly make Haruhi remake reality so that the D.O. never even existed.

[[folder:Comic Books]]
* In one GoldenAge story, one of the things that ComicBook/PlasticMan told Woozy Winks that convinced him to make a HeelFaceTurn was, "What would your mother think?" (Referring to his life of crime.) This line was homaged when Plas guest starred in an issue of the 1990s ''Power of Comicbook/{{Shazam}}'' series and faced a gang of hoods. Unfortunately, in this case the hoods' reaction was "[[YourMom Don't talk about our mothers!]]"
* Lieutenant David Elliot Hanneth Solomon, from ''ComicBook/{{Soda}}'', is a cop faking to be a priest for the sake of his beloved cardiac mother.
* ''ComicBook/SinCity'':
** In the original ''Sin City'' comic (later renamed ''The Hard Goodbye''), Marv visits his mother's apartment to pick up the handgun he stored under his childhood bed. When his noise wakes her up he tells her some lies to reassure her about himself and why he's there that night.
** Becky from ''The Big Fat Kill'' gives this as part of her reason for [[spoiler:selling out the rest of the girls of Old Town to the mob]].
--->'''Becky:''' Sure, you could have protected my mom! Sure! You could have moved her into Old Town and let her know her daughter's a god damn whore!
* In the original ''ComicBook/TheHood'' mini Parker Robbins keeps lying to his mother about him being a SuperVillain. Helps that she has Alzheimer's and doesn't remember when he changes his story.
* Sandman, a ''ComicBook/FantasticFour'' and ''Franchise/SpiderMan'' villain, ''completely'' kept his mother in the dark about being a villain. He even explained that he changed his name when he became a criminal so she wouldn't find out.
* During ComicBook/{{Norman Osborn}}/The Green Goblin's original death in ''Franchise/SpiderMan'' his last words were a plea to Spiderman not to tell his son Harry Osborn that he'd been the Goblin. This carried over to the first ''Spider-Man'' film.
** For that matter, Peter Parker has gone to great lengths to hide his SuperHero identity from his Aunt May, who is as good as his mother. In at least one version, May has arachnophobia and is thus not overly fond of Spiderman, hence Peter's actions.
** And [[{{Retcon}} when she died the first time]] she revealed that she'd known for quite some time, and was very proud of him.
* [[ComicStrip/FoxTrot Peter Fox]] once gets in a fight with a student. As the principal lists the punishments, Peter agrees to them all, only freaking out at "And of course, I'll have to notify your parents".
* A [[UsefulNotes/TheGoldenAgeOfComicBooks Golden Age]] Franchise/{{Batman}} story was about the Penguin's aunt coming to visit in Gotham City, and he begged the Dynamic Duo to help him put on the facade of being a law-abiding citizen because he couldn't bring himself to disappoint her with the fact that he's a criminal. The story follows with Penguin's aunt believing him to be a weapons developer for the military and that he helps Batman and Robin fight crime.

* In ''FanFic/ConstantTemptation'' Mello, Matt, and Near find themselves in a position where [[AccidentalPervert they have to confess to spying]] on [[ParentalSubstitute L and Light]]. They don't want L to know about it, even if it means facing Kira's wrath:
-->'''Near:''' Are we sure we want to do this?
-->'''Mello:''' It's not like you to have doubts.
-->'''Near:''' I don't usually face such definite trouble.
-->'''Matt:''' [[CasualDangerDialog That is the one thing we can guarantee will happen. We still in agreement over who to confess to?]]
-->'''Mello:''' [[OhCrap Light?]]
-->'''Near:''' [[ThisIsGonnaSuck Light.]]
* In ''FanFic/IfThemsTheRules'' [[Franchise/HarryPotter Tom Riddle]] doesn't want to disappoint [[MoralityChain Harry]] so he makes sure he hides his darker tendencies.
* In ''[[http://archiveofourown.org/works/2543735/chapters/5655182 The Lovers Left Broken]]'', Laurel encounters Thea with some "friends" all varying degrees of drunk and high. In order to get them the others to leave, she threatens to call their parents...and makes it [[CoolAndUnusualPunishment genuine threat]].

* ''Film/AmericanGangster''. Frank Lucas spends the whole film treating his mother like an unwitting InnocentBystander, but towards the end of the movie she tells him that she never asked him where all the family's prosperity came from just so that she wouldn't have to listen to him lie to her. Furthermore, she goes on TheReasonYouSuckSpeech about he's responsible for all the other members of his family being in the drug trade, because they never would have gotten into it if not for him. Then she says that all of them, including her, will walk out on him if he does something as suicidally dumb as declare war on the cops, which was exactly what Frank was planning to do at the moment.
* In ''Film/RushHour'', Detective Carter gets certain information from his criminal cousin by threatening to arrest him, thus notifying their Aunt Bootsie about his dealings.
--> '''Carter:''' Luke, I know what it is you do, and the only reason why I ain't busted your ass is because you're my cousin... and it'd kill Aunt Bootsie.
--> '''Luke:''' ...Why you gotta put Aunt Bootsie in this?
* There was one part in the movie ''Film/{{Bulletproof}}'' where Damon Wayans' character goes along in lying to the mother of Adam Sandler's character in order to reassure her. Note that he blames Sandler's character for ''shooting him in the head'', which shows both how far this trope and RuleOfFunny can stretch.
* This is parodied in ''Film/JohnnyDangerously''. It's painfully obvious to ''everybody'' (including the pope) except for Johnny's mother and his brother that he's a mob boss.
* In ''Film/{{Scream 1996}}'' when Sidney informs [[spoiler:Stu (one of the killers, who is already bleeding to death)]] that she's called the police about the murders, he pathetically breaks down and cries "My mom and dad are gonna be so mad at me!"
* ''Film/{{Goodfellas}}'': Tommy lies to his mother about why he and the guys were there that night to keep her from finding out that [[HairTriggerTemper he'd just killed someone for no real reason]].
* Inverted at the end of the first ''Film/SpiderMan1'' film. "Peter... don't tell Harry." It takes an actor of Willem Defoe's caliber to do all the things the Green Goblin did in that film and still make that last request a TearJerker - and it's doubly poignant when you realize that Peter honored that request. Led to PoorCommunicationKills in the following two movies.
* In ''Film/KungPowEnterTheFist'' the Chosen One enlists a group of men to help him train to fight against the evil Betty, telling them to beat him with sticks until he tells them to stop. After beating him until he's unconscious, the men nervously sneak away, and one of them says "Don't say anything to mom."
* In ''Film/{{Clueless}}'', Dionne pulls this on Murray when she's had enough of his wild antics:
--> '''Dionne:''' You know what? Ok, that's it.
--> '''Murray:''' (mimicking) That's it.
--> '''Dionne:''' You wanna play games?
--> '''Murray:''' (mimicking again) You wanna play games?
--> '''Dionne:''' I'm calling your mother.
--> '''Murray:''' I'm... I'm ca... Oh, wait! Oh, no, no, no, no, no, no. No, wait. Don't call my Ma.
* Invoked in ''Film/TrueGrit'', when a dying man asks Rooster Cogburn to get word to his brother (a preacher). Rooster asks "Should I tell him you were outlawed up?" The response is that it doesn't matter.
* ''Film/TheGauntlet''. Malley calls her mother to inform her that she's fallen in love with a cop called Shockley. In the middle of the conversation, she casually mentions her job as a secretary (she's a prostitute).
* In ''To Be Number One'', Ho ascends from an impoverished refugee from mainland China to the most powerful crime boss in Hong Kong. When he's wealthy enough to bring his family over to Hong Kong, his mother sees the limousine waiting to pick them up and congratulates her son on having made so much money in the rice business.

* In ''Literature/HarryPotter'', when Hermione finds the Weasley twins testing out their homemade joke candies on younger students in [[Literature/HarryPotterAndTheOrderOfThePhoenix Order of the Phoenix]], Hermione demands that they stop. They taunt her by saying "Or what? You'll put us in detention?" Hermione coldly responds with "No, but I will write to your mother." This scares the twins so badly that they immediately comply, an action that has never been seen before or since.
* Odd inversion: Peter Wiggin of ''Literature/EndersGame'' and the ''Literature/EndersShadow'' sequels, rather than having to hide an evil secret, is reluctant to let his parents find out that he has a secret identity as the great [[TheChessmaster Chess]][[BigGood master]] named Locke. When he tells his parents, it turns out that they already knew; and as it happens, Bean and Sister Carlotta [[IKnowYouKnowIKnow knew that Peter's parents knew before Peter knew it.]]
* In ''Literature/TheThornBirds'' (though not the better-known film adaptation), protagonist Meggie's oldest brother Frank runs away from home when she's a girl, after having a fight with their father. [[spoiler:Said fight revealed that Frank was actually the son of a different man.]] Years later, their mother, who doted on Frank, happens to find a newspaper in which an article announces his conviction for a terrible crime. Frank's only comment to the press was "Don't tell my mother."
* Literature/ArtemisFowl really doesn't want his mother to know he's turned to a life of crime in order to sustain his family and continue the search for his DisappearedDad, even if she does suspect he takes after his father in this respect.
* In ''Discworld/GuardsGuards'', one of the things Constable Carrot does on his first night on patrol is shame a bunch of bar-brawling dwarfs into behaving themselves by asking what their mothers would say if they found out. It works.
* Played with in ''Literature/PleaseDontTellMyParentsImASupervillain''. On the one hand, yes, Penny really doesn't want her parents to know she's a supervillain. On the other hand, she never actually says it outright.

[[folder: Live-Action TV]]
* On ''Series/TheWire'', Omar Little becomes enraged at rival gangsters after they violate the Sunday truce and blow his cover to his elderly grandmother.
-->'''Omar Little''': I damn near got that woman killed, yo. Y'all should've seen me in Sinai Hospital while they stitching her up, lying about why somebody wanna shoot me down the street. That woman think I work in a cafeteria.
-->'''Kimmy''': Cafeteria?
-->'''Omar Little''': At the airport, yeah.
-->'''Kimmy''': The airport? Why the airport?
-->'''Omar Little''': 'Cause I know she ain't gonna never go down there to go dining, that's why! Hey, yo, Kimmy, this ain't funny, yo! That woman raised me!
* Spy turned ''Series/TheATeam'' style gun for hire Michael Westen from ''Series/BurnNotice'' spent a long time trying to keep his mother in the dark about things, but ultimately had to break the news to her. Since then, she has played small roles in his operations, even once getting information out of a captive after Michael's interrogation techniques didn't work. Despite this, she wishes he would settle down, and the things she is asked to do sometimes unsettle her.
* A running gag on ''Series/HillStreetBlues'' was Belker constantly booking the same criminal for various minor offenses and the criminal always giving him a fake name. This went on for years, until the criminal was accidentally caught in the crossfire of a gunfight he had nothing to do with. He was mortally wounded and asked Belker to call his mother, finally giving Belker his real name. Belker did so, telling the criminal's mother that her son had been a fine, upstanding citizen.
* In one episode of ''Series/{{Brimstone}}'', Zeke finds out that Gilbert Jax, the guy who raped his wife, is one of the 113 souls that escaped from Hell and that he has to find and send back. He also finds out that Jax has started with his old pattern again. He finds out that Jax is living with mother again, and tracks him to the mother's house. There he encounters the mother and talks to her, although he doesn't have the heart to tell her the truth about her son. Jax returns home at that point, and screams that "Getting my mother involved in this is low, Stone". Zeke defeats Jax, but afterwards still doesn't have the heart to tell his mother the truth, and lets her believe that he sent her son back to Heaven instead of Hell.
* Inverted on ''Series/{{Wiseguy}}'', where federal deep-cover agent Vincent Terranova is forced to mislead his mother into believing he's a criminal. He's deeply troubled by how disappointed she is in her "no-good" son, and immensely relieved when she eventually learns the truth.
* On ''Series/MalcolmInTheMiddle'', Hal and Lois leave the boys home alone for the weekend, and a drug gang commandeers the boys' house for their own purposes. The boys try to think of ideas to get the gang to leave, and Dewey (the youngest brother) suggests telling their mothers. This sounds like a childish idea when Reese and Malcolm first hear it, but it turns out to work perfectly: the gang members' mothers show up, and the whole incident induces enough shame in the gang members that they abandon their plans to take over the main characters' house.
* In ''Series/TheMightyBoosh'', Vince blackmails Bob Fossil into giving him and Howard a gig spot by threatening to call Fossil's mother. Fossil quickly agrees to the demand, mainly because his mother's under the impression he's still being held prisoner by the Vietcong.
** This references back to the original radio series, where Fossil quickly agreed to his late brother's demands under threat of his mother finding out Bob was still alive, given that he'd convinced her that he'd died in Vietnam and didn't [[FateWorseThanDeath have to go and see her]].
* One ''Series/TheManFromUNCLE'' episode had two brothers, feuding THRUSH middle managers, concealing both the feud and the nature of their employment from Mama ... until she turned out to be the THRUSH supervisor who showed up to inspect their operation.
* There was a variation on ''Series/{{MASH}}''. Klinger wasn't truly a criminal (unless you count all his attempts to go AWOL) but he tried to keep his mother in the dark for a long time about him being in Korea so that she wouldn't worry, trying to make her think that he had never been transferred from Fort Dix. He simply had his old pals at Fort Dix take about a hundred pictures of him when he was there, and sent one of them to her whenever he wrote. [[spoiler:As it turned out, however, his mother knew all along, proven when Hawkeye organized an event that brought the families of the whole camp together; seems you really can't hide some things from your mother. In a sweet twist on the trope, she had allowed him to think she believed he was at Fort Dix so that ''he'' wouldn't worry about ''her.'']]
* ''Series/TheColbertReport'' ChristmasSpecial has a variation. When Stephen [[MushroomSamba hallucinates]] Music/WillieNelson and [[LetsDuet they duet]] about a gift for baby Jesus, the last line sung by Stephen is "You're really high/I'm gonna tell your savior!"
* ''Series/TheBorgias'': When Micheletto and Cesare visit the former's hometown Forli, Cesare discovers Micheletto not only has a mother, but she's rather doting and completely oblivious about what [[ProfessionalKiller her son really is]], believing he is studying to become a doctor. Cesare plays along with this lie by posing as his mentor, out of his own amusement.
* ''Series/BetterCallSaul'': Tuco Salamanca, maybe the most terrifying, unhinged gangster in the ''Series/BreakingBad'' universe, feels this way about his sweet abuelita. Is that blood on the carpet? No, abuelita, I just spilled some salsa. Yes, abuelita, Iíll clean it right away, go watch your novelas. No, abuelita, I wonít forget the club soda. Viewers have noted that club soda does jack for removing salsa stains, but it's fairly common knowledge that it's great at removing bloodstains. This implies that abuelita knows ''exactly'' what Tuco does for a living. Either that, or Tuco "spills salsa" on the carpet so often, she really does think you clean it with club soda.
** Similarly, Nacho Varga doesn't want his very morally-upstanding father to know that he runs with the Salamancas, but is ultimately forced to tell him in order to warn him that [[TheDon Hector Salamanca]] wants to use his business as a front and [[AnOfferYouCantRefuse won't take no for an answer]]. Nacho's father is both furious and heartbroken that his son is a criminal and [[IHaveNoSon disowns him on the spot]].
* ''Series/{{Gotham}}'': Oswald "Penguin" Cobblepott keeps his [[EvenBadMenLoveTheirMamas beloved mother]] utterly in the dark after his involvement with the mob, presenting himself as a simple nightclub employee (and later, owner), so that she can be proud of him. When Maroni (who can't touch Penguin while he's under Falcone's protection) strikes at Penguin by telling his mother the truth, Penguin swears revenge, and once in private later, breaks down in tears.
* ''Series/BrooklynNineNine'': Doug Judy's mother, despite Doug being a notorious thief and {{Chessmaster}} extraordinaire, has no clue that her son is a criminal. He tells her that he works at an architecture firm, that he does charity work in his spare time, [[AbhorrentAdmirer and that Rosa is his girlfriend]]. Unlike most examples, Doug is [[AffablyEvil friendly and amiable enough]], both on and off the clock, that one can see why his mother doesn't suspect anything.

[[folder:Newspaper Comics]]
* [[http://www.garfield.com/comics/vault.html?yr=1990&addr=900702 Jon was at Irma's Diner and she pointed out he didn't eat the vegetables]]. He sarcastically asked if she'd tell his mother. When she said that she would, he quickly started eating them. ComicStrip/{{Garfield}} told Irma to tell Jon's mother he ate the dessert first.

* ''Theatre/{{Cabaret}}'' is the TropeNamer: the so-titled number features Sally Bowles singing about how her mother thinks that she's living in a convent in France, or touring Europe with her schoolfriends and a chaperone, while she's really living up the seedy life. The trope itself is not actually invoked in the story however, merely in the performance of the song.

[[folder:Video Games]]
* Subversion: Tony's mom in ''VideoGame/GrandTheftAutoLibertyCityStories''. She knows and approves of his job, and even puts a contract on him when she's dissatisfied with his advancement.
* ''VideoGame/{{SWAT 4}}.'' The serial killer in the second mission sometimes reacts to being handcuffed with this phrase. Of course the chances are that you already tazed or mazed her at this point.
* Invoked in ''VideoGame/{{Simcopter}}''; one of the phrases the player can shout at criminals to distract them is, "Does your mother know what you're doing?"
* ''VideoGame/DeadRising'': "Don't tell [[spoiler:Jessie]] about this".
* ''VideoGame/{{Haze}}'': After you fatally wound [[spoiler:Duvall]], he apparently realizes, for the first time, all the atrocities he's committed while being high on nectar. His final words?
-->Shane...please...[[TearJerker don't tell my mom]]...
* In ''VideoGame/{{Tekken}} 5'', in one of her win poses, Lili bends down to the camera (perspective of the defeated opponent) and says
-->Please don't tell my father.
* The ''[[VideoGame/{{Team Fortress 2}} Meet the Sniper]]" video is made of this. Sniper gets a lot of grief from his parents due to his choice of career.
-->'''Sniper:''' ''[on the phone]'' I'm not a "crazed gunman", Dad. I'm an ''assassin''. ''[{{Beat}}]'' Well, the difference bein' one's a job and the other's ''mental sickness!''
* In ''VideoGame/RiseOfTheArgonauts'', there's a sidequest you receive from a girl named Elpis to ''not'' tell her old and ill parents that she was almost killed in the attack on the palace at the beginning of the game. Instead, she simply wants you to tell her parents she was too busy to see them. You can choose either to lie on her behalf or to tell the truth.

[[folder:Web Original]]
* In ''Literature/{{Worm}}'', [[VillainProtagonist Taylor]] tries her best to hide her activities as the supervillain Skitter from her father.

[[folder:Western Animation]]
* Drakken's mom was probably the single funniest thing in ''WesternAnimation/KimPossible'', one of the reasons for this being that she ''completely believes'' he is a radio talk show host. This despite the fact that he studied robotics, not psychiatry. Then again, anyone ''would'' want to cover up the fact that their world domination schemes were foiled by teenagers.
* Tohru's mom in ''WesternAnimation/JackieChanAdventures'' is unaware that her son was working as a thug for Valmont and not knowing that the latter is a DiabolicalMastermind. All she knew was that Valmont was a rich gentleman and assumed Tohru was doing legitimate work. Because of this, she sees [[HeelFaceTurn working as Uncle's apprentice]] to be an enormous step ''down''.
* ''WesternAnimation/TheSimpsons'' provides the former page quote. When they went to Florida during Spring Break, the local sheriff was disappointed with Joe C. (the foul-mouthed little person who toured with Kid Rock). A parody as much as anything, given the utterly inconsequential matter.
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'':
** [[spoiler: [[AlphaBitch Diamond Tiara]]]] and [[spoiler: [[RichBitch Silver Spoon]]]] are ''terrified'' of their mothers finding out about their attitude problems. A later episode reveals Diamond Tiara is actually afraid of failing at anything, due to her mother's insistence on always being seen as a success, whatever the cost.
** The episode "Stare Master" has the villain set right by Fluttershy threatening to tell his mom on him.
** Subverted in "Bridle Gossip". Applejack tells Apple Bloom not to go into the Everfree Forest or she'll tell Big Macintosh on her. Since she was previously shrunken by Poison Joke, you can see where this is going.
* ''WesternAnimation/{{Stoked}}'': In "A Prank Too Far", the groms were tricked into thinking they accidentally killed Bummer. When it seemed they'd be arrested, Reef begged them not to tell his mother.
* ''WesternAnimation/EvilConCarne'': Hector's blind mother doesn't know he's the head of a terrorist organization trying to take over the world and he wants to make sure she remains ignorant of that fact. [[spoiler:Subverted in that [[MamaDidntRaiseNoCriminal she only pretended she didn't know]].]]
* An episode of ''WesternAnimation/TotallySpies'' shows what happens when this trope is defied. Clover discovers that every girl in school is actually dating the same guy, who was jilted on Valentine's Day and for revenge planned to jilt as many girls as he could at the Valentine's Day dance. Clover exposes him to every girl at the dance, but for a fitting punishment, she told his very large mother that he had been taking expensive jewels from her store to give to the girls as gifts. We then hear rather ominous stomping before his mother bursts into the gym screaming "'''''EUGENE!'''''" The last we hear of the guy is his horrified shrieks.
* In the episode "[[Recap/DarkwingDuckS1E47LetsGetRespectable Let's Get Respectable]]" from ''WesternAnimation/DarkwingDuck'', the villain-vanquishing vigilante is trying to improve his public image, and as a result, is not allowed to use his gas gun or karate skills to take down some criminal thugs. What does he do? He resorts to threatening to tell their mothers. Amazingly, it's more effective than one would think.
* In ''WesternAnimation/TheYearWithoutASantaClaus'', the Miser Brothers are terrified at the thought of MrsClaus going to tell their mother about their squabbling; mostly because this is ''[[NeverMessWithGranny Mother Nature]]'' we're talking about here.

[[folder:Real Life]]
* There's a Stock Joke in aviation that goes:
-->Don't tell mama I'm a pilot; she thinks I play piano in a whorehouse.
** Variations on the same joke refer to lawyers, politicians, and other AcceptableProfessionalTargets.
* Albert "the Mad Hatter" Anastasia, a mobster in the 1930s to 1950s, changed his surname from Anastasi'''o''' so his parents wouldn't read about his crimes in the newspaper. His brother "Tough Tony" Anastasio did not change his surname, but everyone knew their relationship. Perhaps he hoped his parents could plausibly deny being his parents.
