Something about a kid being present brings out the best in people. Even a hard-boiled, foul-mouthed sailor will go the extra mile to clean up his act when a little kid is in the room. Okay, it's not so much the best as embarrassment about the worst, but it suffices. Like when you stuff all your clutter in a bag and throw that bag in the shed when your relatives visit unexpectedly.

Of course, the reason for the censor doesn't have to be a kid. Sometimes it's the TeamMom, sometimes an authority figure, or a MoralityPet of some other kind. The difference between this and ThinkOfTheCensors is that that's a LeaningOnTheFourthWall trope, whereas this is justified in-universe.

Supertrope to CurseCutShort and CensorshipBySpelling. [[ForeignCussWord Y cuando se utilizan otras lenguas para ocultar la verdad a los niņos]]. This may be a reason for the SwearJar. It's also why characters CoverInnocentEyesAndEars.

This is, of course, TruthInTelevision. See also NotInFrontOfTheParrot. SubTrope of LittleBrotherIsWatching.

"They don't know." Rorschach [[PetTheDog pets that particular dog]], because he can see a parallel between her kids and his childhood - except he was ''not'' shielded from his mother's profession.

After this argument, Apatow and his daughter leave to go attend a showing of ''Theatre/{{Spamalot}}'', and the remaining cast and crew begin swearing profusely immediately after their departure. [[spoiler:Later the actors mention that she's still inside the studio. Whether or not this is true is unclear.]]

-->'''Timon:''' [[CurseCutShort Pumbaa!]] [[TropeNamer Not in front of the kid.]]

-->'''Pheobus:''' Ah ah, watch it. We're in a church.
* ''WesternAnimation/ToyStory'' had a slight variation but still the same idea:
--> '''Woody:''' The word I'm searching for, I can't say, because there's preschool toys present.

[[folder: Literature ]]

* The hardened soldiers of the borderlands in ''Literature/TheWheelOfTime'' series have a great deal of respect for Aes Sedai, and really try to watch their language. This causes some of them a great deal of difficulty.
* In ''Discworld/{{Thud}}'', when Lady Sybil and young Sam spend time at Pseudopolis Yard, the officers begin combing their hair, speaking quietly, and wiping their boots at the door.
* In a ''Literature/TheSavannahReidMysteries'' novel, Savannah asks Dirk if he wants ice cream, and Dirk replies, "[[IsTheAnswerToThisQuestionYes Do bears sh-]]" [[CurseCutShort Savannah cuts him off]], saying that there's a minor in the house and he should watch his language.
* Salvatore "Sally" Sweet of the StephaniePlum books is a walking ClusterFBomb, until he gets a job as an elementary school bus driver, whereupon he starts wearing a rubber band around his wrist as a pain deterrent for when he swears.
* Maureen Smith relates, in ''Literature/ToSailBeyondTheSunset'', one of her many tactics for dealing with her many children. Retreating to another room for a serious discussion is futile; the children ''will'' hear. Better to simply speak in French. And when the eldest learn French, switch to Spanish. And when the next few learn Spanish, switch to German...
* From the ''AuntDimity'' series:
** In ''Aunt Dimity and the Deep Blue Sea'', Sir Percy takes Lori and her five-year-old twins to his island castle. When Lori is asking a member of Sir Percy's staff about his experience with children, Sir Percy intervenes, saying, "Andrew's also had specialized training that fits him for the job. Damian and I will tell you all about it ''after Rob and Will leave''."
** In ''Aunt Dimity and the Family Tree'', Lori tries to warn Bill off a secret topic by saying, ''"Pas devant les infants,"'' only to have her son Will ask, "What's 'not in front of the children'?" His twin brother Rob informs her that Nell is teaching them French.

[[folder: Live Action TV ]]

* Subverted or played straight in the first episode of ''Series/ArrestedDevelopment'' depending on whether its the tv version or the uncut version. When Michael is talking to his brother GOB about a magic trick he plans to do, GOB says "An ''[[InsistentTerminology illusion]]'', Michael. A trick is something a whore does for money." He then notices a bunch of kids staring at him, jaws dropped. In the TV version, he quickly says "Or candy." However, in the uncensored version, he says "Or cocaine."
* One episode of ''Series/{{Castle}}'' brought Castle's daughter, Alexis, into the precinct and subverts this.
--> '''Javier Esposito:''' Found your stalker. Franco Marquez, AKA Frankie Markie. Hayley filed half a dozen complaints against him. Says here that he even tried to break into her apartment and when she filed against him he showed up in court and called her a...
--> [stops, looks at Castle and Alexis]
--> '''Javier Esposito:''' B I T C H.
--> '''Richard Castle:''' She can spell, Detective.
--> '''Kevin Ryan:''' Probably better than you!
** Similar to the ''HowIMetYourMother'' example below, in the [[http://www.youtube.com/watch?v=sEpxa6EXrOw first season blooper reel]], NathanFillion (Castle) accidentally swears in front of Molly Quinn (Alexis). Although she's not really a kid, she is a minor, and apparently Fillion [[SwearJar gives her a dollar each time he swears in front of her.]]
** The commentary to the first season episode, "A Chill Goes Through Her Veins", includes a number of the actors and show creator, including Molly Quinn. Huertas (who plays Esposito) mentions a modelling gig in GQ with an a fellow actor in the episode, and Quinn interrupts with "Minor!" and Huertas stammers, laughing, to a halt. It wasn't a dirty story. It was ''GQ''.
** Subverted in "Linchpin" when Beckett argues with Castle over an old flame of his, while Alexis was assisting Lanie in the lab.
-->'''Castle''': Okay, we slept together, a long time ago! What's the big deal?\\
'''Beckett''': No big deal, sleep with whoever you want, the more the merrier!\\
'''Alexis'''(clearing her throat) I have those toxicology reports you wanted, Lanie. (Castle glares at Beckett, who looks suitably mollified.)
* The third season of ''Series/HowIMetYourMother'' had a blooper reel which gave us this trope. Cobie Smulders swore over screwing up a line in front of a six year old.
--> '''Smulders:''' No, I'm gonna totally fuck...! [hand in front of mouth]
--> '''Wide-Eyed Kid:''' ... Did you just say the f-word?
--> '''Smulders:''' No, I didn't, I said, uh, [[BlatantLies "Frosted Toasty-O's"]]
** This is played with all the time on ''How I Met Your Mother'', as Older Ted keeps censoring parts of the story for the sake of his kids. Thus we get things like the guys getting high on "sandwiches", Barney shocking a crowd by saying "kiss her" instead of the F-word (and then telling security to "kiss off! Who the kiss are you?"), and [[Film/LethalWeapon Roger Murtaugh's]] CatchPhrase:
---> '''Murtaugh:''' I'm too old for this sh--
---> '''Narrator!Ted:''' Stuff! He said 'stuff'!
* ''Series/{{Friends}}'':
** Phoebe is feeling guilty about spending time with her biological mother and imagines that her mother has been [[CloudCuckooLander reincarnated as a cat.]]
---> '''Phoebe:''' I think someone's upset that there's a new ''mom'' at the B E A C H. [{{Beat}}] I just spelled the wrong word.
** When Monica and Chandler are trying to have a baby, they babysit Phoebe's triplets. They start to make out and Chandler says he's not comfortable doing it in front of the B A B Y. Later, Joey comes in and says "You can't have S E X around a B A B I E!"
** When Phoebe gets Monica and Chandler a ''Ms. Pac-Man'' machine as their wedding gift, Chandler wastes no time in making dirty high-score initials. With Ross bringing Ben over, Monica orders the dirty initials removed; when Phoebe fails her last attempt to remove the final dirty name with a high score, she launches a foul-mouthed tirade right when Ross and Ben walk in, forcing Ross to put "earmuffs" on Ben.
--->'''Ross''': PHOEBE!
--->'''Phoebe''': Oh, hi Ben--NO, DON'T LOOK AT THE SCREEN!
** When Ross and Rachel think Emma's about to speak, they avoid swearing around her. Rachel tells the others to "get ready to hear a lot of 'boo hockey', 'gosh darn it' and 'brother pucker'."
* ''{{Series/Dexter}}'': Debra won't swear in front of Dexter and Rita's infant son. She's dropped f-bombs on live television and in a hospital waiting room full of children, though.
* There's an episode of ''Series/NightCourt'' in which a guy dressed as Santa Claus is brought up before Judge Stone for something involving a prostitute, and there's a kid present, so Stone has people do this.
* On ''Series/DrQuinnMedicineWoman'', Loren often finds himself cleaning up his language whenever Brian is around. One ep had Loren telling some friends about a burlesque house where the girls lift up their...voices! To sing so beautifully!
* When we meet Dawn on ''Series/BuffyTheVampireSlayer'', everyone spends most of a season trying to keep the slaying away from her. They don't talk about it in front of her, except insofar as they can do so in code (they mostly fail).
** They even trying spelling things on occasion, only for Dawn to remind them that she's 15.
* On ''Series/{{Greek}}'', one character does this while he's discussing a FriendsWithBenefits relationship and sees a Nun: "[[CurseCutShort Fu ...]] ''n'' Buddies."
* In [[https://www.youtube.com/watch?v=4pn0n_-rM4E one of the sketches]] of ''Studio C'', it's Bring Your Daughter to Work Day and the dads are cops at a murder scene, so they all have to change the terminology they use to make it child appropriate, like gunshot wounds are "fairy kisses" and blood is "glitter."
** It backfires when one dad says "No, dear, the pony was totaled, it's gonna have to be compacted and sold for individual parts."

* In ''VideoGame/MassEffect3'', [[SirSwearsALot Jack]] has become a teacher at Grissom Academy and has agreed not to swear for the sake of professionalism. This gets turned around when Joker snarks that they could probably buy a cruiser with her SwearJar.

[[folder: Web Original ]]

* In the episode of ''WebVideo/TheAngryVideoGameNerd'' where he reviews the ''Franchise/{{Halloween}}'' video game, The Nerd appears to subvert the trope by swearing like a sailor in front of kids and shitting in a trick-or-treat bag. However, a sharp eyed viewer will notice that he never swears while [[ManipulativeEditing in the same frame]] as one of the kids. The Nerd may avert the trope, but James Rolfe plays it straight.
* Adorably, a little boy [[InvokedTrope invokes]] the trope in [[http://notalwaysright.com/pint-sized-profanity-patrol/22742 this]] Website/NotAlwaysRight story.

[[folder: Western Animation ]]

* ''WesternAnimation/TheSimpsons'':
** Grandpa Simpson babysits Selma's adopted daughter and modifies his old war stories to be baby-friendly.
--->I was just telling her how we chased the teddy bears into their cuddle bunkers, ''[in a creepy voice]'' then had to tickle them out with machine hugs and fun throwers! ''[sinister zoom-in]'' They say the more soldiers you tickle, the easier it gets. Well, sir, it doesn't.
** Moe does a similar thing while babysitting Maggie, telling her a bedtime story which is a cleaned up version of ''Film/TheGodfather''.
** In "Who Shot Mr Burns? (Part 1)", Homer sends Bart and Lisa out of the house before unleashing an AtomicFBomb.
* ''WesternAnimation/TinyToonAdventures'': The episode "[[http://www.youtube.com/watch?v=GQvr_2jJ3P8 To Bleep or Not to Bleep]]", featuring Fowlmouth, turns on this trope.
* ''WesternAnimation/TimeSquad'': In one episode before Tuddrussel and Larry have a heated argument they briefly hold it so they can send Otto out of the room.
