* ''Webcomic/{{Evon}}'' [[http://evoncomics.com/?p=1660 Invoked by Evon]] in the wake of meeting her half-brother.

-->'''Lance Sterling:''' What happens in the sub, ''stays'' in the sub.

* Dunban will invoke this in a certain post-battle conversation in ''VideoGame/XenobladeChronicles1'', as it's a better alternative than acknowledging and talking to Reyn about an IncrediblyLamePun.

* ''WesternAnimation/TeenTitansGoToTheMovies'': As Starfire asks the Justice League if they had their own films, Green Lantern (John Stewart) states that there ''was'' [[Film/GreenLantern2011 a Green Lantern movie]]. [[TakeThat Then he says that they don't really speak of it.]]

-->'''Fraiser:''' He had his shoulder punctured by an alien time capsule device. Erm... three knee operations... that's the whole Hathor incident which he's asked me never to discuss.

* ''WesternAnimation/FetchWithRuffRuffman'': The Season 2 finale, minus the stinger at the end, ends with Ruff and the kids promising to never talk about the incident ever again.

* ''LightNovel/NyarukoCrawlingWithLove'': The PrettyFreeloaders are setting up their own rooms and Mahiro goes to see how they're coming along. He walks into Cuuko's room and sees it's a StalkerShrine to Nyarko...and Cuuko herself is in the middle of humping a body pillow with Nyarko's picture on it. [[DeadpanDoorShut Mahiro silently backs out, closes the door]], and says "I'll just pretend I didn't see that."

** ''Film/GuardiansOfTheGalaxyVol2:'' After Baby Groot brings Yondu and Rocket a severed toe instead of the prototype control fin for Yondu's arrow weapon, Rocket asks Yondu if there's a fridge full of severed body parts on the the ship. Yondu looks down and shakes his head.
--->'''Rocket:''' Okay. Then let's agree to never discuss this.

Compare YouDidntSeeThat, NeverSayThatAgain, ThatDidntHappen, and BigLippedAlligatorMoment.

* ''Series/TheMandalorian'': The titular character is at one point forced to show his face, the one thing his clan's creed absolutely forbids, while infiltrating an Imperial base. He's disturbed to the point of near-catatonia for abandoning his peoples' most solemn oath, although his ally on the mission tries to comfort him by saying [[IDidWhatIHadToDo he did what he needed to do]], and tells him "I never saw your face". It provides him very little personal comfort though.

* The trope image comes from ''Webcomic/EightBitTheater'', after... [[NoodleIncident some shenanigans]] caused by the nightmare inducing poison the Light Warriors had recently unwittingly ingested.
** Black Mage also insisted that they should never speak of the werewolf encounter again, on the grounds that - since the werewolves had thoughtfully decided to [[IgnoredEnemy start bickering and ignore them]] - it was the most pathetic battle ever and not worthy of remembering.
** Drizz'l also invokes this trope after he and the other four Dark Warriors end up sleeping (and spooning) inside of a yeti corpse for warmth

* ''Webcomic/OneOverZero'': Used by the characters after a revelation from Tailsteak.

* In the Franchise/MarvelCinematicUniverse fic "[[https://archiveofourown.org/works/39334239/ What If...Multiverse of Madness: The Clea Cut]]", when America Chavez sends Peter Parker, Wanda Maximoff and Doctor Strange through various alternate realities, they each end up witnessing embarrassing worlds for all three; a world where Wanda and Stephen are married and doing a stage magic show, a world where Wanda is basically a cartoonish villain, and a world where Spider-Man is a Broadway show known for the dancers having accidents. All three agree to the others' request that everyone act as though they never saw that.

* In ''Series/BabylonFive'', after learning the secret of the [[ExoticEquipment "tentacles"]] Londo was using to cheat at cards, Lennier decides to swear an oath of silence on the matter.

* The first episode of ''Series/BlackMirror'', "The National Anthem", plays this trope for severe drama. The episode's TwistEnding reveals that [[spoiler:the MadArtist who kidnapped Princess Susannah actually released her half an hour ''before'' the Prime Minister was forced to have sex with a pig on live television; this was part of his larger point about [[HumansAreBastards how horrible people are]], as he correctly guessed that they'd all be [[BileFascination too obsessed with watching the act]] to go outside and find her]]. When the Home Secretary finds out about this, she promptly tells her officials to "lose that page of the report", implying that no one can ever know the secret. The episode ends about a year in the future; since nobody is discussing the truth, it's implied that the gag order was successful.

* In ''Series/BabylonFive'', after learning the secret of the "tentacles" Londo was using to cheat at cards, Lennier decides to swear an oath of silence on the matter.

* In the ''Series/{{Merlin|2008}}'' episode "[[Recap/MerlinS03E06TheChangeling The Changeling]]", Gaius is adamant that Merlin never mentions again how he (Gaius) has to flirt with AbhorrentAdmirer Grunhilda (a pixie disguised as old maid) to lure her into the vaults and imprison her.

*** In "Skin of Evil", Tasha's funeral speech was supposed to include an apologetic "Data, it ''did'' happen." It's clear to see where it was supposed to be, as they left in Geordi's reaction shot. Subsequent mentions seem to differ on whether or not this line was in effect.
*** During Data's trial [[WhatMeasureIsANonHuman to determine whether he is a full-fledged person with rights]], Data is reluctant to reveal what happened between them, telling Picard that he "gave [his] word", and Picard has to convince him that Tasha would understand given the circumstances, suggesting that Data still believed that Tasha wanted him to keep it a secret.
*** On the other hand, the incident is also alluded to in ''First Contact'', which leans towards suggesting that he did get the message that "it did happen". However, this is also after the Borg Queen had put him through the wringer emotionally (including messing with his emotion chip), so it's equally possible that he would never have revealed it normally, but was so overwhelmed by the situation that he inadvertantly let it slip.
** ''Series/StarTrekEnterprise'': "In a Mirror, Darkly" features this darkly amusing exchange between Mirror Tucker and Mirror T'Pol:

'''T'Pol:''' I'd hardly call it a favor, you enjoyed yourself.\\

*** Averted when B'Elanna Torres tries this in "Blood Fever" after a similar MateOrDie is barely averted. Tom Paris [[UncomfortableElevatorMoment stops the turbolift]] and insists they ''do'' talk about it, as they're going to be stuck on the same ship for years.
*** Played straight in "Counterpoint", where after Janeway subjects the villains to a HumiliationConga, they decide to erase all records of their interactions with Voyager so their superiors won't learn of how badly they screwed up.

* ''LightNovel/NyarukoCrawlingWithLove'': The PrettyFreeloaders are setting up their own rooms and Mahiro goes to see how they're coming along. He walks into Cuuko's room and sees it's a StalkerShrine to Nyarko...and Cuuko herself is in the middle of humping a body pillow with Nyarko's picture on it. Mahiro silently backs out, closes the door, and says "I'll just pretend I didn't see that."

* Another serious example can be found in ''Literature/{{Animorphs}}'': after recruiting David into the group, the Animorphs are forced to deal with the consequences when the kid goes rogue and tries to either kill his former friends or sell them up the river. Eventually, they are able to defeat him by [[spoiler:tricking him into transforming into a rat and luring him into a trap. Unwilling to kill him but unwilling to let him get away with his crimes, they wait for ShapeshifterModeLock to set in, then [[FateWorseThanDeath abandon him on a desolate island with no hope of rescue]].]] Deeply shaken by [[DirtyBusiness what they've just done]], Ax comments that he never wants to speak about what happened ever again.

* Spoken by an assassin named Whip to his driver in the ''Literature/JoePickett'' novel ''Stone Cold'' when he's being driven away from the scene of a hit he just performed and the victim turns out to [[NotQuiteDead still be alive]] and sits up (whilst in the body bag) in the back seat, prompting Whip to unload another few slugs into his head for good measure.

-->'''Luigi:''' [[DudeWheresMyRespect Why do you always get everything]], even the [[Film/SuperMarioBros Mario Brothers movie?]]\\

* In chapter 18 of ''[[https://archiveofourown.org/works/25927015/chapters/63016108 Crimson and Noir]]'', Tikki gets sick and instructs Adrien to take her to the massage shop where the Guardians Fu and Marianne are staying and to tell them that she is a cat needing spiritual healing. Unaware that the old couple knows who he and Tikki are and doubting that they would believe Tikki was a cat, he tells them that she is his pet naked mole rat, much to her annoyance when she gets better. Later in chapter 29 when Crimson Beetle and Lady Noir meet the guardians, [[CallBack Fu brings up the incident by referring to Crimson's Miraculous as "the Miraculous of the Naked Mole-Rat]], Tikki says they will not speak of it again, and hisses to Crimson not to tell Noire when she asks for some context.

* In ''VideoGame/GodOfWarRagnarok'', Mimir tells Kratos that he heard that he participated in a tournament, then clarifies that it involved "beasts, scoundrels, princesses, the undead, automatons and... the world's greatest musician", suggesting that ''VideoGame/PlayStationAllStarsBattleRoyale'' is canon. Kratos just mumbles out "I would not speak of this" and Mimir drops it.

* In ''VideoGame/GodOfWarRagnarok'', Mimir tells Kratos that he heard that he participated in a tournament, then clarifies that it involved "beasts, scoundrels, princesses, the undead, automatons and... the world's greatest musician", suggesting that ''VideoGame/PlaystationAllStarsRumble'' is canon. Kratos just mumbles out "I would not speak of this" and Mimir drops it.

HilarityEnsues because a character must perform an act that is either against their nature or which they have vehemently and constantly protested against doing. Said action can also be just plain humiliating or all of the above--to all parties, perhaps. When this act is aided or witnessed, a character insists that either they must all never speak of this again, ''ever''; or that a specific person who is guaranteed to ride them never hears of it.

This trope can be used to introduce a NoodleIncident, with one character reminding the other they promised never to speak of that again. Alternatively they may have just completed the action, make some passing reference to how unusual or interesting it was, and then pull this line.

* Done at the end of the "Time and Fate" level of ''VideoGame/CallOfDutyBlackOpsII''. The mission is capturing Raul Menendez, but Manuel Noriega lets him go and he goes on a rampage concurrent with the CIA raid. The mission ends back at the hotel Menendez and his sister had been in, as [[spoiler:Frank Woods, crazed from the sorts of torture Menedez performed on him, throws a grenade.]] As they get clear of the rubble and Menendez is dragged away in a body bag, the player's commanding officer informs them at "from this point on, today never happened."

*** [[UnreliableExpositor Varric]] claims that this is what the Qunari said about the Arishok's unauthorized invasion of Kirkwall in ''VideoGame/DragonAgeII''.

%%** The whole incident with "[[{{Crossdresser}} Magical Girl Inferno Aniki]]" in Chapter 33.
%%** The entire crew [[RepressedMemories represses their memories]] of [[spoiler:Anime/BaronOmatsuriAndTheSecretIsland]]

* ''Fanfic/JWITCHSeason1'': Ratso paraphrases this to the other Enforcers regarding him touching the rear of Uriah, a minor, to take Ikazuki's mask off ([[EvenEvilHasStandards which he's very uncomfortable with]]). And at the end of the chapter, the whole J-WITCH team agree to never discuss how Uriah [[PottyFailure ended up soiling himself]] after getting knocked out by Uncle.

* In chapter 18 of ''[[https://archiveofourown.org/works/25927015/chapters/63016108 Crimson and Noir]]'', Tikki gets sick and instructs Adrien to take her to the massage shop where the Guardians Fu and Marianne are staying and to tell them that she is a cat needing spiritual healing. Unaware that the old couple knows who he and Tikki are and doubting that they would believe Tikki was a cat, he tells them that she is his pet naked mole rat, much to her annoyance when she gets better. Later in chapter 29 when Crimson Bug and Lady Noir meet the guardians, [[CallBack Fu brings up the incident by referring to Crimson's Miraculous as "the Miraculous of the Naked Mole-Rat]], Tikki says they will not speak of it again, and hisses to Crimson not to tell Noire when she asks for some context.
