4->'''Jesse:''' You know how you have those experiences you remember and reminisce about for the rest of your life?\

6'''Jesse:''' This isn't one of those. Let's never discuss this ever again.

9A 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.
10
11Or to put it another way, "What happened here ''stays'' here."
12
13This 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.
14
15Subversions can occur when the character(s) kept in the dark reveal themselves to have [[EverybodyKnewAlready known all along]] or if the character who would have used the incident as ammunition, against all expectations, chooses ''not'' to do so. Sometimes that somebody will bring it up again, earning the reaction "I thought we agreed to never speak of it again" or something close to that.
16
17It can be parodied by the person(s) who are told to never mention it again being genuinely unaware of what happened for whatever reason, leading them to ask something like "Speak about what again?", which is then taken by the person wanting the secret kept as a joke implying compliance with their wish.
18
19Prequels occasionally resort to this trope as a way to justify their events ''not'' being mentioned in works that were written earlier, but set as a later date in-Verse.
20
21Will often be PlayedForLaughs (as the thing that will never be mentioned was usually something funny/embarrassing) or PlayedForDrama (especially if the event was something that happened between [[ShipTease two characters who]] [[WillTheyOrWontThey may or may not end up together]].

When they end up uncovering Jess' personal collection of [[PornStash dirty adult magazines he had hidden under his bed]] (he's a teenage boy, what'd you expect), the two girls' reactions are somewhere between the lines of this trope.
92* In the Franchise/MarvelCinematicUniverse fic ''[[Fanfic/BecauseIKnewYou 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 [[Theatre/SpiderManTurnOffTheDark Spider-Man is a Broadway show known for the dancers having accidents]].

It's okay though. It's just the one. I managed to shoot the tube, just as Hermione got the containment shield up. That reminds me. We need to write this down.\

181** The whole incident with "[[{{Crossdresser}} Magical Girl Inferno Aniki]]" in Chapter 33 is so disturbing for the crew that they ask Chopper to cook up a potion to erase their memories. Except for Luffy, who somehow forces the memory out of his mind.

She promptly injects him with the antidote to her pheromones and they agree to pretend it never happened.
192* ''Fanfic/TheNewAdventuresOfInvaderZim'':
193** Zim and Dib apparently have this understanding regarding the canon episode "Bolongius Maximus" (the one where they're turned into boloney).
194** Dib and Viera quickly come to this understanding in Season 1 Episode 21, with him never bringing up her [[spoiler:[[LotusEaterMachine dream illusion]] presenting her as an anime magical girl]] in exchange for her not questioning how he's so experienced with the DreamWalker spell.

217** Most of the various victors (particularly the Rebel ones) do their best not to bring up what they did in the Games in front of each other thanks to both the associated trauma and because of the circumstances of survival in the Games means that normal standards need not apply. A good way to piss a Victor off is to defy this rule and degrade them for something that happened in their Games; Blight did this frequently, which led to many of his fellow Victors (mostly Careers, as Blight hates them) hating his guts and wanting to kill him.
218* In ''Fanfic/OneGirlWithTenBrothers'' (a ''[[WesternAnimation/TheLoudHouse Loud House]]'' RuleSixtyThree fanfic), the Loud siblings have all agreed never to discuss a NoodleIncident concerning how the boys reacted to Linka getting her first period.

223* In ''Fanfic/PokemonResetBloodlines'', Pikachu reveals to Ash how, back in the old timeline during [[Anime/Pokemon2000 the events of the second movie]], [[CPRCleanPrettyReliable Misty had to perform CPR on him after he almost drowned]], and made Tracey (the only human who witnessed it) swear he'd never tell anyone or else, ''especially'' Ash himself.
224* The ''Fanfic/JWITCHSeries'': Ratso paraphrases this trope 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.
225* In ''Fanfic/MarriageOfHeavenAndHell,'' Makoto invents a technique to destroy armor called Armor Break, but when he uses it for the first time, it ends up [[TheNudifier destroying the opponent's clothes]] as well, i.e. Dress Break.

228* In the ''VideoGame/FireEmblemThreeHouses'' fic ''Fanfic/AnEagleAmongLions'', when Edelgard and Hilda from an AlternateTimeline briefly return to their original bodies after [[spoiler:Alternate Hilda dies fighting Thales and Nemesis in Shambhala]], they immediately start making out upon seeing each other again. The original Edelgard and Hilda [[TeethClenchedTeamwork still don't get along after being on opposing sides in the war]], and are confused and disgusted by their alternate selves being SickeninglySweethearts. When the alternates disappear and the originals realize that they're still kissing, they pull away from each other and vow never to do anything like that again.
229* In the ''Fanfic/FacingTheFutureSeries'', Danny and Sam are temporarily turned into toddlers. After returning to normal, they make Tucker promise not to show anyone the picture he took of them. He ends up showing Valerie, who is unable to contain her laughter when she sees Danny and Sam.
230-->'''Danny:''' ''(Flatly to an unamused Sam)'' He showed her the picture.
231* ''Fanfic/GoinKaboom'': When Pinky brings up the time he and the Brain used to live with Elmyra, the Brain reminds Pinky that they agreed to "never speak of that again".
232* ''Fanfic/DannyPhantomStranded'': In "Envied", when Misty's mom asks if she's "trying out for cheerleading again" after hearing her jump, Misty reminds her they "agreed to never speak of that again".
233* In chapter 18 of ''Fanfic/CrimsonAndNoire'', 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.
234* ''Webcomic/NaruHinaChronicles'': Kei recalls when Miho allowed Yuko to feel her up. Miho then panics and tells Kei that the latter promised her to never mention it again and that it didn't happen. However, Kei is confused and says "I... did?!"
235* ''Fanfic/CheatingDeathThoseThatLived'': The Fifty-Seventh Hunger Games are such a disaster (with a schizophrenic Victor being the least of its issues) that Snow refuses to acknowledge they ever happened for the rest of his life, to the point that he doesn't bother stationing anyone to watch over the arena, like he does with the others. [[spoiler:[[HoistByHisOwnPetard This backfires when Trevy and his gang use it to hide out themselves and Wattzon during the Second Rebellion]]]].

245* In ''WesternAnimation/PenguinsOfMadagascar'', Skipper invokes this after the team dress up in lederhosen [[WeNeedADistraction to distract the octopi]].
246-->'''Skipper:''' We take this shame to our ''graves''.\
247'''Kowalski:''' Agreed.
248* ''WesternAnimation/TeenTitansGoToTheMovies'': As Starfire asks the Justice League if they had their own films, Green Lantern (John Stewart) states that there ''was'' a ''Film/{{Green Lantern|2011}}'' movie. [[TakeThat Then he says that they don't really speak of it.]]

250-->'''Peter:''' [[TakeThat We don't really talk about this.]]
251* ''WesternAnimation/HowToTrainYourDragonTheHiddenWorld'': The Light Fury gleefully knocks Hiccup off of Toothless, who then swoops down to save him. When next we see Hiccup:
252-->'''Hiccup:''' ''[as his companions snicker in the background]'' ''Not'' a word.
253* ''WesternAnimation/SpiesInDisguise'': During their escape inside a submarine, Walter hugs Lance (in pigeon form) so tighly, that he suddenly lays an egg and says this to Walter after uncomfortably finding out.
254-->'''Lance Sterling:''' What happens in the submarine, ''stays'' in the submarine.
255* ''WesternAnimation/PhineasAndFerbTheMovieCandaceAgainstTheUniverse'': When the characters exceed the speed of light, reality breaks down to its primal essence- the storyboards, and then Dan and Swampy pitching the scene. When the scene returns to normal, they are deeply weirded out.
256-->'''Ferb:''' We should never speak of this again.
257-->'''Phineas, Isabella, Buford and Baljeet:''' Agreed.
258* ''WesternAnimation/ABugsLife'': After Flik is revealed as a liar, the queen insists that the colony hides all this and pretends it never happened, and the bugs were never here. It doesn't last.
259[[/folder]]
260
261[[folder:Films — Live-Action]]
262* The ''Film/StarskyAndHutch'' film has this in spades. After Starsky (Ben Stiller) and Hutch (Owen Wilson) have to do some fairly embarrassing things to get information out of a con, Hutch starts to talk about it in the car ride back, and Starsky shuts him. "No! No! Let's not talk about it. In fact, let's never speak of this again." Of course, when they get back to the station, it's been recorded and is playing in the Captain's office with all of the other officers watching.
263* In the film version of ''Film/TheLordOfTheRingsTheTwoTowers'' Gimli tells Aragorn use him in a FastballSpecial (a reference to a scene in the [[Film/TheLordOfTheRingsTheFellowshipOfTheRing first movie]] in which he objected to being thrown by Legolas). He asks Aragorn not to tell Legolas. Aragorn promises not to say a word.
264* In ''Film/TheHobbit'', Dwalin threatens to rip a child's arms off if he ever tells anyone how they snuck into Bard's house via the chamber pot.

267* ''Film/TheHuntForRedOctober''. After Admiral Greer fakes the torpedoing and destruction of the ''Red October'', he tells the torpedo control officer of the frigate he's on:

270* In the end of ''Film/{{Zathura}}'', [[spoiler:Lisa says this to her younger brothers, mainly because the Astronaut she thought was hot turned out to be a future version of Walter]]. They bring it up anyway.
271* Burt Gummer says this after surviving being swallowed by a Graboid in ''Film/Tremors3BackToPerfection''.
272-->'''Burt:''' I would prefer... we keep this... to ourselves.
273* ''Film/WildWildWest'': When Jim West gets [[ItMakesSenseInContext stuck to Artemis Gordon's belt buckle]], he tells Gordon to make sure and leave that part out when retelling the story. Artemis responds with a very emphatic "Oh don't worry."
274* ''Film/PulpFiction'':
275** A less funny example: after Butch saves him from Zed's... attentions, this is the first of Marsellus Wallace's demands before letting him go:
276--->'''Marsellus Wallace:''' Don't tell nobody about this. This shit is between me, you, and [[RapeAndRevenge Mr. Soon-to-Be-Living-the-Rest-of-His-Short-Ass-Life-in-Agonizing-Pain Rapist here]]. It ain't nobody else's business.
277** Earlier, Vincent Vega and Mia Wallace both agree not to tell anyone, especially Mia's husband Marsellus, that she almost died of a heroin overdose and Vincent had to inject adrenaline directly into her heart to keep her alive.
278* In ''Film/WithoutAPaddle'', the boys are stranded in the woods in their underwear. They take shelter from the rain in a cave and are forced to share body heat to survive. They all agree, "This never leaves the cave."
279* In ''Film/{{Pixels}}'', Violet shoots a dancing pixel smurf, because it creeps her out. To her teammates' shocked stares she says:
280-->'''Violet:''' Please don't tell anyone I shot a Smurf.
281* ''Film/TheMartian'', at the very end, when Mark Watney is addressing a class of new entrants to NASA's Astronaut Candidate Program:
282-->'''Watney:''' Yes, I really did survive on Mars by farming in my own shit, and it was even worse than it sounds so let's not talk about that ever again.
283* In ''Film/JusticeLeague2017'', Aquaman accidentally sits on Wonder Woman's Lasso, and as a result, blurts out several things like how he thinks they will all die on their mission and that he thinks Wonder Woman is hot.

284* ''Franchise/MarvelCinematicUniverse:''
285** ''Film/GuardiansOfTheGalaxyVol2:'' An imprisoned Yondu and Rocket have tasked Baby Groot with retrieving the prototype control fin for Yondu's [[TrickArrow arrow]]. Cue a montage of him constantly grabbing the wrong things, including an entire desk, Vorker's prosthetic eye, and finally a freshly severed human toe.
286--->'''Rocket:''' ...Tell me you guys have a refrigerator somewhere with a bunch of severed human toes. ''[Yondu shakes his head]'' Okay. Then let's just agree to never discuss this.
287** ''Film/AntMan1'': [[spoiler:Sam "The Falcon" Wilson gets his ass kicked by a guy called Ant-Man who's only power is to shrink to the size of an ant, and who constantly apologizes for fighting him]]. Afterwards, this gem happens:
288--->'''Falcon:''' It's really important to me that Cap never finds out about this.
289* In ''Film/OneHundredAndTwoDalmatians'', when the clinic that cured Cruella discovers that their brain altering therapy is reversed by the sound of Big Ben's bell, they immediately vow to disavow any knowledge of Cruella's treatment.
290* PlayedForDrama in ''Film/TheTown'', as Doug asks James for help with essentially nothing to go on. James agrees immediately.
291--> '''Doug''': I need your help. I can't tell you what it is, you can never ask me about it later, and we're gonna hurt some people.
292-->'''James''': ...[[TrueCompanions Whose car we gonna take]]?
293* In ''Film/MadameWeb2024'', after learning about Ezekiel from her mother's notes, Cassie wonders if she can climb walls like him. She tries and fails miserably, and then tells the stray cat she occasionally feeds that they shouldn't share it with anyone.

296[[folder:Literature]]
297* ''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.
298* ''Literature/BringUpTheBodies'' has a serious example with Henry VIII's near-fatal jousting accident, in which he was unconscious and thought dead for hours and the court began splintering into factions for another civil war. He tells Cromwell that the events of the afternoon must never be mentioned, for the stability of the realm and to keep foreign powers from getting ideas, and Cromwell agrees--the official story will be that he was out for ten minutes at most and it was no big deal.
299* ''Literature/CaptivePrince'': When Prince Laurent's party is intercepted by soldiers while deep in enemy territory, he gets DisguisedInDrag offscreen; not only are the soldiers fooled, one quietly says that "Lady Jokaste" is [[AttractiveBentGender just as beautiful]] as the stories say. Damen tells a bemused Nikandros not to think about it.
300* ''Literature/{{Discworld}}'':
301** After the events of ''Literature/{{Sourcery}}'', the surviving wizards of the Unseen University swear blind they weren't there, but away visiting their relatives in far-off countries. All except for Archchancellor Ridicully, who really wasn't there.
302** ''Literature/LordsAndLadies'': No one should even ''mention'' the Stick and Bucket Dance. Not '''ever'''. [[spoiler:At least, not once the Lancre Morris Men are done using it to kick elven ass.]]
303** In ''Literature/WitchesAbroad'', after the witches take part in it, nobody mentions the Thing With The Bulls ever, ever again. At least not around the men.
304** Strongly implied to have happened at the very end of ''Literature/{{Night Watch|Discworld}}'' between Vimes and Dr Lawn, who happens to be the only living person besides Lord Vetinari who could testify to the main plot of the book having happened, with an ''extremely'' large sum of money changing hands to seal the deal.
305* ''Literature/AHoleInTheFence'': The reason why people know nothing of or refuse to talk about the Forbidden Zone beyond of Courquetaines is that [[spoiler:a part of the country's population decided to abandon their cities, seclude themselves in the High Country and live like farmers in a restored and healthy environment forty years ago. So a high fence was built, and both parties agreed to never talk again about the fights, strife and social which led to that situation]].
306* ''Literature/JoePickett'': Spoken by an assassin named Whip to his driver in ''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.
307* ''Literature/JourneyToChaos'': Team Four went on a mission to Najica between ''Literature/AMagesPower'' and ''Literature/LoomingShadow'', and it was so embarrassing for Tiza and Nolien that they both agreed to forget it. Basilard, however, will not let them forget it because it involved some serious disciplinary action.
308* At the conclusion of ''[[Literature/MythAdventures Myth-ion Improbable]]'', Aahz, Skeeve and Tananda promise never to reveal what they've witnessed on Kowtow or even discuss it among themselves. This conveniently explains why the events of this Interquel didn't rate a single mention in the dozen-odd books to follow.
309* In ''Literature/PrideAndPrejudiceAndZombies'' the Bennet girls come across a zombie mother and infant and find themselves unable to kill them. Afterward they swear never to mention it again.
310* ''Literature/{{Redwall}}'': A very serious example: by the end of ''Martin the Warrior'', Martin is so overcome by the events of the novel that he vows never to bring them up again and pretend they never happened. This is, out of universe, because the book is a prequel, and there's no mention of these events in the books set later on featuring Martin.
311* A serious example appears in ''Literature/FireAndBlood'', a prequel to ''Literature/ASongOfIceAndFire''. Both the Grand Maester Benifer and the Hand of the King Septon Barth decide to keep mum about the death of Princess Aerea Targaryen after her trip to unknown lands-- though not before informing King Jaehaerys I, prompting him to ban any sort of travel to Valyria. Considering the horrific manner of Aerea's death [[spoiler:(turned into a breeding nest for some sort of [[Franchise/{{Alien}} Xenomorph]]-like horror)]], one can scarcely blame them.
312* ''Franchise/StarWarsLegends'': In ''[[Literature/StarWarsScoundrels Scoundrels]]'', the CaperCrew agrees to never mention the job to anyone when it's all over, given the [[GambitPileup unusual outcome]]. For a book that takes place just after ''Film/ANewHope'', this neatly explains why, say, Han and Winter act like they only know each other through Leia in ''Literature/TheThrawnTrilogy'', or Kell never brings up the fact that he's met Han (who is at that point far superior to him in rank in the New Republic military) in the Literature/XWingSeries.
313-->'''Han:''' By the way, that thing about never mentioning this to anyone? That goes double for Her Highness.\
314'''Winter:''' Absolutely.
315* ''Literature/WarriorCats'': In ''Midnight'', a human girl has picked up Feathertail, who is unable to escape the girl’s grip without hurting her. Squirrelpaw decides to act cute to try to distract her, which works. She then informs the others that she’ll claw them if they tell anyone she purred at a Twoleg.
316* ''Literature/TheWheelOfTime'': Part of the [[ProudWarriorRaceGuy Aiel honor code]] is that it's dishonorable to remind someone of an old debt of honour after it's been paid. As such, there's a scene where Egwene confesses a lie to her Aiel mentors, submits to a painful and humiliating punishment, and everyone moves right on afterwards.
317* ''Literature/TheSavannahReidMysteries'': In ''Killer Honeymoon'', Savannah's gang gets in a fight with a guy and they're losing when it's ''five against one''. They're saved by Granny Reid and a taser. Dirk announces afterward that they should never speak of that humiliating moment again.

320[[folder:Live-Action TV]]
321* In the ''Series/BabylonFive'' episode "[[Recap/BabylonFiveS01E21TheQualityOfMercy The Quality of Mercy]]", 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.
322* ''Series/TheBigBangTheory'':
323** After returning from a research grant in Antarctica, Leonard, Sheldon, Howard, and Raj repeatedly talk about how they weren't going to talk about "the night the heat went out." Sheldon, being Sheldon, brought it up anyway. (They huddled together naked.)
324** In one episode, Penny got a new chair that she had found thrown out at the curb. [[TerrifiedOfGerms Sheldon]] freaked out over the chair, telling Penny to get rid of it, with Penny dismissing his concerns... [[ProperlyParanoid until she and Amy discovered that something was crawling around in the chair's lining]]. As the two girls raced out of Penny's apartment screaming, they agreed not to [[JerkassHasAPoint let Sheldon know he was right]].
325* In ''Series/BlackBooks'' while reminiscing/complaining about their terrible holiday, they stumble on one part they weren't supposed to bring up.
326-->'''Fran:''' And remember when those tribesmen thought Manny was a god?\
327'''Manny:''' Yes, it'll be quite some time before I want to sacrifice another monkey.\
328''[Bernard lunges across the table and seizes Manny by the shirt]''\
329'''Bernard:''' [[NoodleIncident WE SAID WE WOULDN'T TALK ABOUT CANADA!]]
330* The first episode of ''Series/BlackMirror'', "[[Recap/BlackMirrorTheNationalAnthem 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.
331* One skit for the "Music" episode of ''Blue Collar TV'' featured Creator/JeffFoxworthy and the gang (including special guest Creator/DrewCarey) going for a hunt in the woods. Instead, it turns into the four of them doing increasingly-corny musical performances. At the end, Jeff proposes:
332--> '''Jeff:''' I think we make a deal right now. What goes on in the woods...''(everyone else, including the audience joins in)'' '''stays in the woods!'''
333* ''Franchise/{{Buffyverse}}'':
334** ''Series/BuffyTheVampireSlayer'':
335*** From "[[Recap/BuffyTheVampireSlayerS5E2RealMe Real Me]]":
336---->'''Buffy:''' How bored ''were'' you last year?\
337'''Giles:''' I watched ''Series/{{Passions}}'' with Spike. Let us never speak of it again.
338*** In "[[Recap/BuffyTheVampireSlayerS7E19EmptyPlaces Empty Places]]", Spike and Andrew have an exchange on their mutual love of onion blossoms while en route to a mission, ending with:
339---->'''Spike:''' Yeah. ''[beat]'' Tell anyone we had this conversation, I'll bite you.\
340'''Andrew:''' Right.
341*** In "[[Recap/BuffyTheVampireSlayerS4E7TheInitiative The Initiative]]", a vampirized Harmony meets Xander and decides to feed. They apparently regress to their grade school enemy stage (since both of them ''can'' fight better), and they're so ineffectual that they eventually just give up. They agree it never happened, and both leave.
342*** In "[[Recap/BuffyTheVampireSlayerS4E1TheFreshman The Freshman]]", Xander after telling Buffy he was once roped into working as a male stripper. "...and no power ''on this Earth'' will make me tell you the rest of that story."
343** ''Series/{{Angel}}'' played it for laughs in "[[Recap/AngelS05E20TheGirlInQuestion The Girl in Question]]". The head of Wolfram and Hart's Rome branch used it several times.
344--->'''CEO lady:''' ''[spit]'' We will speak of it no more!
345* ''Series/ControlZ'': Following Susana's accidental death, Sofía, Javier, Raúl, Pablo, María, Alex and Claudia make a pact to cover up their involvement and not speak of it ever again.
346--> [from trailer] '''Raúl:''' We'll all make a pact. We're not saying a word to anyone, okay? We'll never talk about this again. And we live our lives as if none of this ever happened.
347* ''Series/{{CSINY}}'': After the death of a colleague, Stella and Adam have a [[SexForSolace one-night stand.]] Later at work as things are a bit awkward, they hastily agree that it must never, ever happen again.
348* ''Series/DoctorWho'':
349** At the end of "[[Recap/DoctorWhoS2E6TheCrusade The Crusade]]", a bunch of Crusaders agree this to prevent being branded insane after they see the TARDIS dematerialise.
350** Played for drama at the end of "[[Recap/DoctorWhoS9E2TheCurseOfPeladon The Curse of Peladon]]", where King Peladon, distraught over Hepesh's failed coup and subsequent death, orders the day's events to be scrubbed from the kingdom's official history.
351** "[[Recap/DoctorWhoS28E12ArmyOfGhosts Army of Ghosts]]": The Doctor, when the head of Torchwood finds out that the woman he'd claimed was Rose Tyler is actually Rose's mother.
352--->'''The Doctor:''' Please, when Torchwood comes to write my complete history, don't tell people I travelled through time and space with her mother.\
353'''Jackie Tyler:''' Charming!
354** "[[Recap/DoctorWhoS29E2TheShakespeareCode The Shakespeare Code]]": Two of Creator/WilliamShakespeare's acting troupe agree to this after inadvertently (and thankfully, temporarily) summoning a [[SealedEvilInACan Carrionite]] while reading aloud the WordsOfPower inserted into the play's script by the MonsterOfTheWeek.
355** "[[Recap/DoctorWho2017CSTwiceUponATime Twice Upon a Time]]" {{avert|edTrope}}s it. After hearing Bill Potts call his future self an arse, the First Doctor threatens her with a smacked bottom if he hears language like that again. An utterly mortified Twelfth Doctor ''begs'' Bill to pretend that never happened. Bill however rejects this, as she wants them to spend years sharing a laugh over that one, because she's just happy to know the Doctor is alive and to be working with him again.
356* ''Series/{{Friends}}'':
357** Ross and Richard are having a sleepover at Rachel and Monica's. At one point they bump into each other in the living room, wearing their girlfriends' bathrobes. After a few awkward seconds they attempt small talk, but then Richard cuts to the chase and says "Let's never speak of this again." Ross says "You got it." and they move on.
358** Also in "The One Where Joey Loses His Insurance", Joey thanked Chandler for helping him take a shower when he had a hernia, and Chandler freaked out and said, "Now, is ''that'' never talking about it again?!"
359** And there's the time that Monica is stung by a jellyfish. A friend who will pee on you is a friend indeed.
360* ''Series/GreysAnatomy'':
361** Invoked almost verbatim by Cristina in the episode "Complications of the Heart", after a surgery wherein both she and the more experienced Dr. Altman forgot how to perform a very basic procedure and ended up needing the nurse to bail them out.
362** Also nearly word by word in the episode "Physical Attaction… Chemical Reaction", during one of the many "awkward sex" scenes, when Izzie and George try fantasy to revive their chemistry. It does not end pretty.
363--->'''George:''' I think I chipped my tooth.
364* ''Series/{{Heroes}}''. Just so there are no misunderstandings, Nathan can fly:
365-->'''Matt Parkman:''' ''[after riding Nathan Petrelli to Texas]'' We never talk about that again.
366* ''Series/ICarly'':
367** Between the Shay siblings, notably, Carly's NoPeriodsPeriod in "iDate a Bad Boy" and Spencer's attempt at giving Carly TheTalk in "iSpeed Date".
368** Sam and Freddie's agreement about their First Kiss. When Sam's drugged slip-of-tongue reveals it to Carly, HilarityEnsues.
369* ''Series/{{JAG}}'': When Admiral Chegwidden receives a mysterious tape with no return address in his office, he has Petty Officer Tiner play it. [[spoiler:It is a video of the Admiral's fiance dressed seductively holding the roses he sent her quoting Shakespeare and inviting him to a very special dinner.]] The Admiral cuts the tape off midway and tells Tiner to never speak of this again. Tiner wisely claimed nothing happened.
370* This causes problems in ''Series/{{Longitude}}'' during a field test of Harrison's chronometer. He determines that the headland in sight is a particularly dangerous one, while the admiral has insisted that it's a different place, and it takes some effort to convince the ship's captain the truth. Though the fleet is prevented from hitting the rocks, the captain and the admiral hush up the fact that they nearly made the same deadly mistake that ''started'' Parliament's efforts to fix UsefulNotes/TheLongitudeProblem, leaving Harrison at the mercy of hostile bureaucrats until the ship's master delivers his own private testimony.
371* A common occurrence on ''Series/TheLoveBoat'' as the crew will spend the episode on some zany adventure and when it's done, agree it's best not to let the Captain know about it and never mention it again.
372** When Gopher complains about seeing Isaac's aunt in a horrible play and it being the worst shore leave experience, Doc states he had a worse time with his second wife. "But per our divorce agreement, I'm legally prohibited from ever discussing it."
373* ''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.
374* In the ''Series/Merlin2008'' 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.
375* In the series 5 episode 1 of ''Series/{{Misfits}}'', Alex develops the power to [[IntimateHealing remove the powers of others by having sex with them]]. Meanwhile, Finn gets [[DemonicPossession possessed by the devil]]. Alex has to use his new power to get rid of the devil. Afterwards, Alex and Finn try to get the group to agree never to speak of this again. Rudy, being Rudy, keeps bringing it up.
376* [[PerkyGoth Abby]] from ''Series/{{NCIS}}'' mentions that the team agreed to this regarding her [[MustHaveCaffeine Caff-Pow-drinking record]]: "It got ugly."
377* Almost verbatim on ''Series/ThePeterSerafinowiczShow''. Upon making a breakthrough deduction in a case, Sherlock Holmes [[spoiler:becomes so sexually aroused that he forces himself on Watson. In post-coital reflection]], Holmes says "We shall not speak of this again."
378* The crew of ''Series/RedDwarf'' went so far as to erase their memories and bury the blackbox after an incident where Lister gave Rimmer some memories of one of his ex-girlfriends.
379* ''Series/{{Rome}}'':
380** Cleopatra wants to use TheBabyTrap on Caesar, but knowing that Caesar has no sons, (and possibly needing a distraction from her withdrawal symptoms after GoingColdTurkey) she decides to increase her chances of pregnancy by sleeping with one of the legionnaires that Caesar sent to escort her to him. She first orders [[TheStoic Vorenus]] to sleep with her, but Vorenus (despite being sorely tempted) refuses due to fidelity to his wife and Roman sexual attitudes to the idea of being "used" for sex. Vorenus then orders the other legionnaire, [[BoisterousBruiser Pullo]] to "Report to Princess Cleopatra and do whatever she tells you to." Cue a prolonged and [[TheImmodestOrgasm noisy]] bout of sex, much to the discomfort of Vorenus. When Pullo returns, they have the following conversation:
381--->'''Pullo:''' Gods, that was something, let me tell you.\
382'''Vorenus:''' I don't want to hear about it. If you're wise, you'll never speak of this again.\
383'''Pullo:''' Why? [[JustFollowingOrders I was only obeying orders]]. Bloody good orders, too.
384** When the youthful Octavian comes home after being kidnapped in Gaul, then rescued by Vorenus and Pullo, his rather shallow mother fusses over him. "Was it very horrible?" (''Octavian opens his mouth'') "Of course it was, we shan't even talk about it. Let's put it totally out of our minds."
385** Played for drama when Pullo and Octavian discover that the wife of Vorenus has had a child with another man. They murder the man responsible and swear never to speak of it to anyone. Unfortunately Octavian relates the story to his sister, who tells it to someone involved in the conspiracy to murder Julius Caesar. They use the tale to [[WeNeedADistraction lure Vorenus away from Caesar's side]] on the day of the assassination.
386* In one episode of ''Series/{{Scrubs}}'', Dr. Cox invokes this trope after Dr. Kelso gives an all-too-graphic description of his and Mrs. Kelso's recent sexual encounter.
387* In ''Series/{{Seinfeld}}'', George dates a woman who looks like Jerry. George tries to come up with things that the relationship can be 'about' so as not to deal with the idea that he might harbour homosexual feelings for Jerry. The woman gets gum in her hair and cuts it out, making her hair short like Jerry's. George runs away screaming. Later, at the coffee shop, George and Jerry are talking about the incident and George says 'We must never ever speak of this'. Afterwards Jerry awkwardly asks George if he wants to go and see a movie. George refuses, instead saying that he's 'going to take a few days off', which Jerry agrees is probably for the best.
388* ''Series/StargateSG1'': Way back in the first season, the Goa'uld Hathor took over Stargate Command and [[LivingAphrodisiac used pheromones to control the male population]]. Several seasons later, Dr. Fraiser is going over O'Neill's medical files.
389-->'''Fraiser:''' He had his shoulder punctured by an alien time capsule device. Erm... three knee operations... ''[puts aside a large stack of folders]'' and that's the whole Hathor incident which he's asked me never to discuss.
390* ''Franchise/StarTrek'':
391** ''Series/StarTrekTheNextGeneration'':
392*** The episode "[[Recap/StarTrekTheNextGenerationS1E2TheNakedNow The Naked Now]]" features all sorts of weird events when the ''Enterprise'' crew falls under the influence of a virus that basically makes everyone more than a little drunk (including Data). One scene features Data meeting up with Tasha Yar in her quarters, where they end up having sex. After the virus has been purged and everyone is sober again, Tasha and Data are back at work on the bridge, where she tells him, "I'm only going to say this once: It never happened."
393*** In "[[Recap/StarTrekTheNextGenerationS1E22SkinOfEvil 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.
394*** During Data's trial [[WhatMeasureIsANonHuman to determine whether he is a full-fledged person with rights]] in "[[Recap/StarTrekTheNextGenerationS2E9TheMeasureOfAMan The Measure of a Man]]", Data is reluctant to reveal what happened between them, telling Picard that he [[IGaveMyWord "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.
395*** On the other hand, the incident is also alluded to in ''Film/StarTrekFirstContact'', 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.
396** ''Series/StarTrekEnterprise'': "[[Recap/StarTrekEnterpriseS04E18InAMirrorDarkly In a Mirror, Darkly]]" features this darkly amusing exchange between Mirror Tucker and Mirror T'Pol:
397--->'''Tucker:''' I did you a favor once.\
398'''T'Pol:''' We agreed never to discuss that.\
399'''Tucker:''' And I haven't.\
400'''T'Pol:''' I'd hardly call it a favor. You enjoyed yourself.\
401'''Tucker:''' Several times as I recall. So, how many years is it 'til your [[MateOrDie pon farr]] comes around again?
402** ''Series/StarTrekVoyager'':
403*** Averted when B'Elanna Torres tries this in "[[Recap/StarTrekVoyagerS3E15BloodFever 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.
404*** Played straight in "[[Recap/StarTrekVoyagerS5E10Counterpoint 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.
405** Season 2 of ''Series/StarTrekDiscovery'' ends with [[spoiler:the titular starship being sent over 900 years into the future to prevent a rogue AI from using her to carry out the apocalypse]]. Afterwards, everyone involved with the incident is sworn to never speak of it under penalty of treason.
406* Dean invokes this in ''Series/{{Supernatural}}'' when he has to talk [[IncompatibleOrientation Charlie]] through flirting with the male security guard with Sam listening in. Sam never does mention it again, but that doesn't keep him from laughing his head off all the way through it.
407* ''Series/{{Taxi}}'': Latka is furious at Alex for sleeping with his (Latka's) mother and--more to the point--not agreeing to marry her and become Latka's new papa. According to him the only way they can get past it is his country's tradition of "globnik", meaning "to pretend or assume some event or occurrence never took place."
408-->'''Alex:''' You think that would do it? I mean, just pretend it never happened?\
409'''Latka:''' Pretend what never happened?\
410'''Alex:''' (beat, smiling) Beats me.\
411'''Latka:''' Me too.\
412'''Alex:''' Well, back to work.
413* In an episode of ''Series/{{Victorious}}'', Tori prompts this to Kat after seeing on the news they accidentally set an actress's house on fire and got the person injured and sent to the hospital.
414* ''Series/TheWestWing'' {{lampshaded}} its frequent use of the WalkAndTalk by having Sam and Josh walking through the crowded hallways having a conversation as usual. At the end, they both came to a stop and asked each other where they were going. Turns out they were both following each other.
415-->'''Josh:''' Let's not tell anyone about this.
416* In ''Series/WhiteCollar'' episode "Power Play", Neal and Peter have to swap identities. This leads to Peter asking the whole office to go along with it.
417-->'''Peter:''' Listen up, everybody. For the next hour, and only the next hour, you will call Mr. Caffrey Special Agent Peter Burke. No questions, no laughing, just do it. And never speak of this again.
418* In an episode of ''Series/WouldILieToYou'', Neil Morrisey, voice of WesternAnimation/BobTheBuilder, had as one of his "facts" that he once had a builder working at his house who was in fact named Bob. David Mitchell said that if that was true, it was completely unremarkable, and the conversation probably went, "Do you know, I'm actually a builder called Bob." "Right. I do the voice of Bob the Builder." "Right." [short laugh all around] "Let us never speak of this."
419* In ''Series/{{Riget}}'', after once particually chaotic night at the neurosurgical department where [[spoiler:Dr. Mortensen shot Dr. Helmer in the leg for spurning her, the "deceased" Dr. Krogshøj turned out to be OnlyMostlyDead and has returned to work like his "death" never happened, and the hospital priest was very brutally and messily killed by the satanic powers at play at the hospital]], Dr. Moesgaard resolves to only mention all these events with a short comment each during the daily morning briefing and then immediately follows up by telling everyone present that he doesn't want to discuss any of these events in any kind of detail, and either should they.
420[[/folder]]
421
422[[folder:Podcasts]]
423* Quoted during Podcast/RiffTrax's take on ''Film/TheLastAirbender'' after they see [[MemeticMutation The Pebble Dance]].
424* In the ''Podcast/ThrillingAdventureHour'', Sparks Nevada and Croach are in rare agreement that they will never speak of the Sparks having to stimulate Croach's egg sacs to show his feet to the Space Crazy Preacher.
425[[/folder]]
426
427[[folder:Radio]]
428* ''Radio/OurMissBrooks'': A [[HilarityEnsues series of mistakes]] in "Dress Code Protest", gets Mr. Conklin stranded in his office pantless and forced to wear Miss Brooks' badly-torn skirt to coverup. Mr. Stone, head of the Board of Education, finds him dressed this way. To get him out of trouble ([[BewareTheNiceOnes and get back at Mr. Conklin for, earlier in the episode, claiming only Miss Brooks ever gets into ridiculous situations]], Miss Brooks claims Conklin is playing a native girl in a school play. Mr. Conklin dances a hula while Miss Brooks sings "it also happens to you" to the tune of "Aloha Oe". The scheme works. However, later that night, Mr. Stone asks Miss Brooks when the school play would be performed. The entire school board wanted to see Mr. Conklin sing, wear the skirt, and do the hula! Miss Brooks dryly informs Stone that Mr. Conklin wouldn't be doing the hula or dressing in a skirt ever again!
429[[/folder]]
430
431[[folder:Roleplay]]
432* Agent Supernumerary of the ''WebOriginal/ProtectorsOfThePlotContinuum'' game is quite specific about the fact that when he says it's "unspeakable," that means he does ''not'' want Agent Suicide to keep talking about that little incident with a reality-warping typo and some very surprised goblins.
433[[/folder]]
434
435[[folder:Tabletop Games]]
436* In TabletopGame/ChuubosMarvelousWishGrantingEngine, saying this outright is one of the way to write off a [[BigLippedAlligatorMoment break from reality]].
437[[/folder]]
438
439[[folder:Theme Parks]]
440* In the former ''[[Theatre/SpecialEffectsShow Special Effects Stages]]'' at Ride/UniversalStudios, after one of the volunteers got mauled by [[FluffyTheTerrible Fluffy the robotic werewolf]], the host would say this to the volunteer's family.
441[[/folder]]
442
443[[folder:Video Games]]
444* In ''VideoGame/HarmoKnight'', Master Woodwin, after talking to you once you [[spoiler:beat the [[TheVeryDefinitelyFinalDungeon Final Trial]] level]], tells you to never talk about him losing his staff again. Because, as he says, that would press the princess's BerserkButton.
445* ''VideoGame/{{Psychonauts}}'': There's a Mental PhlebotinumBreakdown in Sasha's mind, and a horrible mutated monster comes up and proceeds to pound the living daylights out of Sasha in a highly embarrassing fashion. Raz saves Sasha's life, for which Sasha grants him his merit badge. This conversation then occurs:
446-->'''Raz:''' So, is this the part where I get a speech and learn another lesson...?\
447'''Sasha:''' No. Here is your merit badge. Let us never speak of this again.
448* ''Franchise/{{Persona}}'':
449** ''VideoGame/Persona3'':
450*** The {{Love Hotel|s}} Incident, in which the Lovers Arcana Shadow tries to make the party get intimate with each other. In the male route, a humiliated Yukari threatens him into silence. In the female route, Akihiko or Junpei take it in better stride, but find it too awkward to ever bring up again. Presumably, the same thing happens on Mitsuru's end, as when you find her with Junpei, Akihiko, or Yukari, she'll flush and angrily deny anything happened.
451*** The aftermath of Mitsuru's "[[MaximumFunChamber Execution]]" during the Kyoto class trip. Akihiko is ''[[HeroicBSOD very insistent]]'' about this point. Even if you avoided being [[HumanPopsicle executed]], all characters involved agree to never admit to anything, lest they incur Mitsuru's wrath.
452** ''VideoGame/Persona4'':
453--->''[the team's gathered in a classroom to discuss the case]''\
454'''Yosuke:''' But man, seeing [Kanji] here kinda reminds me of the school campout.\
455'''Kanji:''' I thought we were all gonna forget about [[HorribleCampingTrip what happened]]...\
456'''Yosuke:''' Oh... Sorry.\
457''[all three guys look depressed]''
458* ''Franchise/DragonAge'':
459** ''VideoGame/DragonAgeOrigins'':
460*** Sten says this to Leliana when she sees him playing with a kitten and picking flowers.
461*** Also comes up after the threesome/foursome with Isabela in ''The Pearl''.
462---->'''Zevran:''' I don't mind never speaking of it again, as long as we could do it again.\
463'''Leliana:''' There's a thought...
464** Something of a RunningGag in ''VideoGame/DragonAgeInquisition''.
465*** [[UnreliableExpositor Varric]] claims that this is what the Qunari said about the Arishok's unauthorized invasion of Kirkwall in ''VideoGame/DragonAgeII''; Varric assumes that this is pretty much the closest they'll get to an official apology from [[TheStoic the Qunari]].
466*** If [[PlayerCharacter the Inquisitor]] is a human mage, the [[TheArchmage First Enchanter]] of the Ostwick Circle of Magi said this in response to [[NoodleIncident something bizarre]] that happened during the Inquisitor's Harrowing.
467*** If the Inquisitor is a Qunari, one of the other members of their mercenary band said this to a donkey after an EscortMission [[NoodleIncident apparently went south]].
468*** After the player finds Cassandra [[spoiler:reading "smutty literature" that had been written by Varric]] she asks that you pretend you don't know that about her.
469* In ''VideoGame/{{Fairune}} 2'', upon rescuing the Red Fairy, she freaks out over the heat of the [[LethalLavaLand lava caves]] she was imprisoned in, and bolts for the exit teleporter. Upon reuniting with her at the Entrance, she has this to say:
470-->'''Red Fairy''': ''I must have made a terrible impression there. PLEASE, FORGET ALL ABOUT IT.''
471* In ''VideoGame/CaveStory'', one of your fights with [[GoldfishPoopGang Balrog]] begins after you ''almost'' trick him into helping you with a feat that requires great strength. When you win, he yields and assists you ([[spoiler:this is one of the hints dropped to you that he isn’t really such a bad fellow; [[PunchClockVillain he's just doing his job]]]]). He entreats you, however, not to tell anyone he did it.
472* ''VideoGame/SamAndMaxFreelancePolice: Abe Lincoln Must Die!'' has Sam and Max take a date test to find the perfect match for each other. The result gives... Sam to Max and Max to Sam. Both agree never to speak about it again.
473* One of the categories for the third annual Neopies on ''Website/{{Neopets}}'' is named after this trope.
474* ''VideoGame/DawnOfWarII'' agrees with fans' opinion of the previous ''Soulstorm'':
475-->'''Cyrus:''' Kaurava was a huge mistake... I will not speak of it again.
476* In ''VideoGame/TheElderScrollsVSkyrim'', this is, word for word, one of the dialogue choices available after you let an apprentice mage [[https://www.youtube.com/watch?v=sYqA73LdT5w practice a spell on you.]]
477* ''VideoGame/TeamFortress2'':
478** Suggested with the InUniverseMarketing for [[UrineTrouble Jarate]].
479--->''You may say, "But I don't HAVE any enemies!" Well, do you have FRIENDS? Are they on FIRE? Right NOW? Jarate them to a non-on fire state INSTANTLY! Being on fire is horrible! They'll never want to talk about your Jarate rescue ever again, but you'll have their secret undying gratitude!''
480** On the Special Delivery mission, once the rocket lifts off and immediately crashes the Announcer might have this to say:
481--->'''Announcer:''' Gentlemen, this never happened.
482* In the ''VideoGame/MassEffect3'' Citadel DLC, it is possible for an un-romanced Female Shepard and [[spoiler:Javik]] to [[spoiler:end up in bed together]] after the party:
483-->[[spoiler:'''Javik:''' It turns out there is one thing primitives are good at.]]\
484'''Shepard:''' ''[[PunctuatedForEmphasis Not. A. Word.]]''
485* ''VideoGame/SaintsRow'':
486** Late in ''VideoGame/SaintsRowTheThird'', you need to impersonate [[spoiler:Cyrus Temple, the [[ArmiesAreEvil STAG]] commander, to rescue the kidnapped Shaundi, who is being held in a STAG carrier chock-full of enemies. While following the second-in-command, Kia, the Boss tries to make some chit-chat]]. If you've chosen the "Cockney" voice, [[DevelopersForesight she'll notice and call you out on your sudden British mannerisms]]. The Boss handwaves this by saying that he must have picked them up from a stint in Britain. When she says that there's no record of [[spoiler:Cyrus]] having ever been stationed in Britain, he'll cover for it by claiming he's probably said too much, and they should probably just forget they ever had the conversation.
487** In ''VideoGame/SaintsRowIV'', after being rescued from a Zin simulation, Kinzie warns the Boss to ''never'' speak of the fact [[spoiler:she was forced to wear a poodle skirt.]] The Boss, being, well, [[{{Troll}} the Boss]], attempts to [[TemptingFate bring it up anyways...]]and promptly gets [[MegatonPunch punched so hard]] by Kinzie that [[OneHitKO they immediately respawn]] [[KilledMidSentence before they can even finish the sentence.]]
488* Vegeta while being revived by an ally in ''Videogame/DragonballXenoverse.''
489-->'''Vegeta:''' This never happened, understood?
490* 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 a {{pun}}.
491-->'''Reyn:''' You can't have a rainbow without Reyn, baby!\
492'''Melia:''' Dunban, I think you need to have a talk with Reyn.\

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 and his sister are dragged away in a body bag, the player's commanding officer informs them at "from this point on, today never happened." [[spoiler: Turns out, however, Menendez survived his encounter, while his sister did not; it was this incident which spurred him to start the ''Cordis die'' movement and begin plotting the downfall of Western civilization to avenge his sister.]]
498* ''VideoGame/{{Shantae}}'':
499** ''VideoGame/ShantaeRiskysRevenge'': Mimic tells Shantae they are going to do this once she finds the magic seals because they're supposed to be secret. Of course, considering what happens at the end of the game, that is easier said than done.
500** In ''VideoGame/ShantaeAndThePiratesCurse'', this is Sky's reaction to the events of Tan Line Island, where the girls got mistaken for a princess and put in some...''[[GoGoEnslavement interesting]]'' outfits.
501* In ''VideoGame/SouthParkTheFracturedButWhole'', after the battle against Jared in the police station, regardless of whether the New Kid either farts him into unconsciousness or spares him from being farted on, Human Kite's (AKA Kyle Broflovski's) response is to ask everyone that it's best to forget the encounter with Jared and never talk about it again.
502* PlayedForDrama in ''VideoGame/{{Stellaris}}''. Encounters with the universe's more disturbingly eldritch powers can result in an empire's leader and their scientists agreeing to destroy all data regarding the encounter and take the secrets to their graves.
503* Invoked in ''VideoGame/AnimalCrossingNewHorizons'': The game has fun with the idea that all the Mystery Islands are randomly-generated. We mean, they have a ''heckin' ball'' with it.
504-->'''Wilbur:''' Also, there's one redline item you need to memorize like your latte order: Anything you leave behind stays here. We don't come back to these places. ''Ever.'' [[DestroyTheEvidence I actually burn the flight plans afterward]]. Security reasons. Can't explain more than that.

506* In ''VideoGame/GodOfWarRagnarok'', Mimir tells Kratos that he heard that he participated in a tournament, then clarifies that it involved "[[Franchise/SlyCooper beasts, scoundrels]], [[Videogame/FatPrincess princesses]], [[Videogame/{{Medievil}} the undead]], [[Franchise/RatchetAndClank automatons]] and... [[Videogame/ParappaTheRapper 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.
507* In ''VideoGame/DontStarveTogether'', WX-78 and Maxwell share this sentiment if they were [[ForcedTransformation transformed into Wonkey]] and then changed back.

Surprisingly, Ranpha doesn't get mad at Tact for it, but makes him promise they won't let anybody else find out about this, and the incident doesn't get any further callbacks even on the route Tact pursues a relationship with her.
511* In ''VideoGame/FinalFantasyXIV'', the Warrior of Light and Krile finds Alisaie and G'raha asleep in a gazebo by the Studium. While G'raha flails once he wakes up, Alisaie hops up, faces the Warrior of Light, stares them down and declares that they will ''not say a word'' of this.

518* ''VisualNovel/DanganronpaV3KillingHarmony'': In an optional event, Shuichi quickly tells himself to keep quiet at all cost after taking a peek at the girls while they were putting on swimsuits.
519* After the protagonist of ''VisualNovel/DoubleHomework'' and his classmates escape from the avalanche on Barbarossa, [[spoiler:they all know that the avalanche itself was an attempt to kill all of them, and what can happen if they talk about it in the future]].
520* ''VisualNovel/{{Melody}}'':
521** Subverted if the protagonist and Isabella have a one-night stand in Tim's house. They both agree that they’ll have one night together and move on from it, but Isabella can’t, and she asks the protagonist for more. [[spoiler:And if the two of them become an official couple and ask for Tim's blessing for their relationship, Tim will reveal that he heard the whole thing anyway.]]
522** Melody and Sophia previously agreed to have sex once and then leave anything sexual alone, but Sophia brings it up again, which can lead to the two of them experimenting further.

526[[folder:Webcomics]]
527%%* ''Webcomic/OneOverZero'': Used by the characters after a revelation from Tailsteak.
528* ''Webcomic/EightBitTheater'':
529** The trope image comes from this webcomic, after... [[NoodleIncident some shenanigans]] caused by the nightmare-inducing poison the Light Warriors had recently unwittingly ingested.
530** 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.
531** 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.
532* ''Webcomic/{{Bard}}'': [[http://barred.smackjeeves.com/comics/850119/how-to-improvise/ Vas]] uses his [[GenderBender change of gender]] to quell the rage of one of the more violent patrons by... stuffing her face into his new rack. It takes a bit for this to register with him, though.
533* In ''Webcomic/BlueYonder'', after [[http://www.blueyondercomic.net/comics/1371537/blue-yonder-chapter-1-page-41/ Lena tricks them into fleeing a cellphone]], one attacker tells another, "No one has to know."
534* ''Webcomic/BrawlInTheFamily'': In [[http://brawlinthefamily.keenspot.com/comic/495-comicreviewe32013/ strip #495]], VideoGame/{{Mega Man|Classic}} really does '''not''' want to talk about his stint in the ''WesternAnimation/CaptainNTheGameMaster'' cartoon.
535-->'''[[VideoGame/KidIcarus Pit]]:''' Hey man! Haven't seen '''you''' in a while. Now we just need to get [[Franchise/{{Castlevania}} Simon]]--\

541** [[http://www.egscomics.com/?date=2002-06-15 Elliot seeing Tedd without his glasses]] while being [[GenderBender gender bent]] (and potentially bisexual) gets this reaction. Not that it stopped them from [[http://www.egscomics.com/?date=2005-10-05 speaking of it again]].
542** [[http://egscomics.com/?date=2010-11-19 Grace's suggestion that Elliot turn into her to be sexy in front of a mirror]] seems doomed to a similar fate.
543** In another instance, Grace and Sarah attempted to prank Tedd by using a transformation device to make Sarah look exactly like Grace. Unfortunately, when Tedd encounters Sarah as Grace, he immediately kisses her. While there is no dialogue in the [[http://www.egscomics.com/index.php?id=1823 comic itself,]] the commentary states that they decided to never speak of it again.
544* ''Webcomic/EveryoneIsHome'': When the cast revives [[VideoGame/MetroidPrime Dark Samus]], [[Franchise/KingdomHearts Sora]] guesses that she's "a super gnarly and disturbing alien skeleton" underneath the suit, as in ''Franchise/{{Metroid}}'' canon. Unfortunately, he's dead wrong, because she's an attractive grey-skinned lady beneath the suit.
545-->'''Samus:''' The Internet can ''never'' know about this.[[note]]Unfortunately for ''her'', Sora then takes pictures of unarmored Dark Samus and uploads them into the Internet, much to Samus's frustration.[[/note]]
546* ''Webcomic/{{Evon}}'' [[http://evoncomics.com/?p=1660 Invoked by Evon]] in the wake of meeting her half-brother.[[note]][[SurpriseIncest Who was her first lover]], before she found out who he really was. For the record, he didn't know either at that moment.[[/note]]
547* In ''Webcomic/GirlGenius'', Gilgamesh orders that his hat should be hidden in a safe place--[[http://www.girlgeniusonline.com/comic.php?date=20120116 and never spoken about again.]]
548-->'''[=DuPree=]:''' I heard there was a ''hat!''\
549'''Gil:''' You're ''delusional''.
550* ''Webcomic/GrrlPower'': After a mfm threesome with [[GreenSkinnedSpaceBabe Blue-Skinned Space Babe]] Cora ([[https://www.grrlpowercomic.com/archives/comic/grrl-power-748-sharing-is-scaring/ heavily implied in the strip,]] confirmed by the author's comments), Math and Hiro mutually agree to never speak of this again. To Dabbler's frustration, since she'd like to know every little detail.
551-->'''Math:''' We must never speak of this again.\
552'''Hiro:''' You're breaking the rule!\
553'''Dabbler:''' ''[putting arms on their shoulders]'' Tell. Me. EVERYTHING.\
554''[they both leave without a word]''\
555'''Dabbler:''' But... but I tell you guys everything! No matter how much you beg me to stop!
556* ''Webcomic/{{Homestuck}}'':
557** Karkat takes this to the logical extreme by [[spoiler:trolling John backwards, so that they'll never be able to talk about the first conversation (from Karkat's perspective), where Karkat accidentally reveals his hatecrush for John. Needless to say, it's hilarious.]]
558** Karkat and Sollux apparently once had a chat conversation so embarrassing that they both agreed to permanently delete it from their computers' history.
559** Dave also does this [[http://www.mspaintadventures.com/?s=6&p=002256 early on in the strip]], after royally screwing up his fetch modus and losing the beta in the process, despite there being no one around to have seen him.
560--->'''Dave:''' No one can ever know about this.
561** [[http://www.mspaintadventures.com/?s=6&p=007678 "Let us never speak of ACT 6 ACT 5 ACT 2 again."]]

Afterward, Grape tells Peanut[[note]]who took a picture of the "something", though the viewer never gets to see it[[/note]], "We never speak of this again."
563* In ''Northern Edge'' (a spin-off of Fred Perry's ''ComicBook/GoldDigger''), Sheila just want to forget all about she and two companions being spanked by tentacles. Fat chance of this, though, since there was [[http://ne.tsunami-art.com/view.aspx?Rec=24 a rune artist present on the scene to immortalize it]].
564* ''Webcomic/TheOrderOfTheStick'':
565** While being interviewed for the LawfulGood afterlife, hero Roy Greenhilt stops the deva interviewing him before she can mention a GenderBender incident within earshot of his father, who is standing not ten feet away.
566** During that very incident, Roy also insisted Belkar not know. Subverted in that Belkar knew it was Roy all along and was comfortable enough with his masculinity to hit on Roy purely to mess with him.
567** And during Azure City's New Year, Belkar [[KissingUnderTheInfluence gets drunk and kisses Vaarsuvius full on the lips]]. Afterwards, Belkar forgets it entirely and Vaarsuvius insists that, if the one witness to the kiss (Durkon) ever has to discuss it again, it will be referred to it as "the Event". And they never talk about it again.
568** When Belkar and Hayley's father Ian unleash a dinosaur in order to save two gladiators from execution, Belkar warns Ian not to tell Roy it was his idea, otherwise [[GroinAttack he'd find a sharp way to make sure Hayley stays an only child]]. Ian retorts [[ThreatBackfire he's been as sterile as a mule for ten years ever since he accidentally triggered a poison needle trap]].
569** When Vaarsuvius is rescued from the Semi-Elemental Plane of Ranch Dressing, they mention that there were some adventures before they got there.
570--->'''Belkar:''' Maybe we'll see that as a bonus story in one of the books!\
571'''V:''' Maybe we shall never mention it again.\
572'''Belkar:''' Yeah, probably that.
573* ''Webcomic/QuestionableContent'':
574** In [[http://www.questionablecontent.net/view.php?comic=447 #447]], Marten and [[spoiler:Marten's mother, who is a professional dominatrix]] return to his apartment to find Pintsize wrapped up in bondage gear, which prompts this line to be spoken.
575** Played straight and later averted in [[http://www.questionablecontent.net/view.php?comic=3885 #3885]] when Roko meets Beepatrice for a job interview and they end up oversharing about Roko's bread fetish and Beepatrice's job at a sex toy factory. Beepatrice begs to rewind and start over, to which Roko emphaticaly agrees. After some inane chatter and an awkward silence:
576--->'''Beepatrice''': Can we go back to the first draft? It was more interesting.\
577'''Roko''': I have to admit I am curious about the hydraulic press.
578* ''Webcomic/SamAndFuzzy'':
579** An early strip has Sam win a free cake, which he shares with Fuzzy while gleefully touting what a great friend he is for sharing his cake with him. One bite of said cake both silences him, and shows why it was free in the first place.
580--->'''Fuzzy:''' I thought I was your ''friend''!!!\
581'''Sam:''' ''[eerily calm]'' We will never speak of this cake again.
582** Also during the Noosehead arc, Earl, Noosehead's manager, is trying to figure out how to make lead singer Sid go back to his old bitter, angry self rather than the nauseatingly happy person he has become. His secretary suggests the cause might be the litter of kittens Sid has been playing with (in reality Butcher, the pet cat of Sam, and her kittens). He then asks if Earl hadn't already tried to get rid of them once. Earl did in fact try to remove them, but was attacked by Alonso, the father of said kittens, and an intelligent talking cat.
583--->'''Earl:''' ''NO''\
584'''Secretary:''' Really? Because I'm almost certain you-\
585'''Earl:''' '''NEVER SPEAK OF IT AGAIN'''
586* ''Webcomic/SchlockMercenary'': [[http://www.schlockmercenary.com/2011-05-21 Ennesby to Schlock]], after a particularly [[http://www.schlockmercenary.com/2011-05-20 unpleasant moment]]. Only for Schlock to bring it up again 15 seconds later.
587* In ''Webcomic/{{Shortpacked}}'', when Leslie [[https://www.shortpacked.com/comic/citizen-dinobot questions]] Robin's claim that Ethan represents the average voter, one of the things she references is the CanonDiscontinuity "Second Eaton" storyline. Robin reminds her that they all agreed that never happened.
588* ''Webcomic/SluggyFreelance'' [[http://www.sluggy.com/comics/archives/daily/000419 has a great one]]
589-->'''Crystal:''' My head is killing me. Does anyone remember what happened after the tequila shots?\

591'''Bun-bun:''' I vote we all go home and never speak of this again.
592* In [[http://twolumps.net/d/20050509.html this]] ''Webcomic/TwoLumps'' comic, Eben and Snooch lurk in darkness behind a door, preparing to attack a dustbunny as part of Snooch's lessons... only to be blinded by sunlight because they gave their eyes no time to readjust. When Snooch asks if the blinding is part of the lesson, Eben says no and to not speak of the incident again.
593* ''Webcomic/TheWotch'' combines this with TheUnreveal regarding a past incident between Katie and Jason [[https://www.thewotch.com/?comic=speaking-of-the-past here]]. They discuss the last time they were alone together which still haunts the former. Their dialogue, however, is covered up by that of their science teacher and his student assistants dealing with an explosion and resulting fire ocurring off-panel. By the time the fire's out, they've agreed to forgive, forget, and never speak of the original incident again.
594* ''Webcomic/{{Xkcd}}'': Invoked in the title-text of strip #41 "Old Drawing": "I don't want to talk about it"

He then immediately informs David, "That never happened." And threatens him with murder should his friends ever learn of it.

601[[folder:Web Original]]
602* ''Blog/ThingsMrWelchIsNoLongerAllowedToDoInAnRPG'': Lives up to the trope by only telling us what can't be talked about, but [[NoodleIncident no real details]].

604* A double {{GIRL}} on [[http://www.bash.org/?768122 bash.org]] provokes this reaction from the participants. Subverted. [[HilariousInHindsight Since it's on bash.org and all]].

615* ''WebAnimation/SonicForHire'': In Season 7, after managing to rebuild the entire universe, Franchise/{{Sonic|TheHedgehog}} is surprised at how it was able to be finished [[LeaningOnTheFourthWall in a week]], with Tails stating that he's glad they both agreed to never speak of the logistics of how it was done, giving an AsideGlance.
616* WebVideo/ToddInTheShadows insists, after watching ''Film/StElmosFire'' in order to better explain its one-hit wonder theme song, that nobody ever speak of it again. He breaks his own resolution several times during the episode to rant furiously about how bad the movie is.
617* On ''WebVideo/OutsideXbox'', they take on the ''VideoGame/Hitman2016'' Patient Zero missions. Mike, who plays 47 as a MadBomber who thinks the first commandment is "thou shalt go loud on a regular basis", ended up spending the finale in a ridiculous mass-murder bloodbath that nearly depopulates the level, and comments, "Probably best if we don't speak of this ever again, [[MissionControl Diana]]."

Afterwards Francine remarks that there's nothing like sharing a DarkSecret to strengthen a family's bonds, and they all agree to forget it ever happened.
628* ''WesternAnimation/{{Amphibia}}'': In the episode "Cracking Mrs. Croaker", Mrs. Croaker tells Anne, Spring, and Polly not to go talking about her fight with Jonah.
629* ''WesternAnimation/{{Archer}}'': On his birthday, Archer walks into the office lobby and announces "Paging Dr. Boy! Dr. Birthday Boy!" When he realizes no one is around and a security camera recorded him doing that, he reaches behind the receptionist's desk, takes out the security camera tape and smashes it on the counter.
630* ''WesternAnimation/AsToldByGinger'': In ''Wicked Game'', Dodie and Macie conspire with Miranda and Mipsy to break up the new relationship between Ginger and Darren—the former because they feel left out by Ginger's preoccupation with Darren and the latter because they're petty, jealous, often reprehensible people. Ginger eventually finds out about it, stops talking to Dodie and Macie, and the episode ends on a rather sour note, but afterwards the three of them act as if it never happened. It's implied that they decided to deal with it by just never talking about it.

638'''Freight Train:''' ''[[[RuleOfThree double-long vomit shot]]]''\
639'''Cleveland:''' You can '''not''' tell Donna about this.[[note]]Referring to Auntie Mamma's real nature[[/note]]\
640'''Freight Train:''' Yeah, I'ma be playing this one down in general.
641* ''WesternAnimation/DannyPhantom'':
642** In "WesternAnimation/RealityTrip", Sam wonders how Danny convinced her parents to let her go on a cross-country trip with him and Tucker, and the explanation is thus:
643-->'''Sam's Mother:''' ''[being overshadowed by Danny]'' You know I think the Fentons are wonderful, Sam should take a cross-country trip with them.\

652::: Chris then attempts this. It does not have the intended effect.
653--->'''Peter:''' ''[beat]'' Chris. I'm going to stand up. Walk out of this room. And we will never speak of this again.
654::: The best part of the exchange is that the tone of Peter's voice makes it clear he is VERY freaked out by the whole thing.
655** Also the time where Peter is blind and accidentally gets into Chris's bed at night...

657--->'''Meg:''' [[LampshadeHanging So, this is one of those things we just never talk about again?]]
658** Lois encourages Chris, in one episode, to find a job. When she finds out that he's has been working as Quagmire's assistant, she is very creeped out by the things he's been doing. Finally, she tells Chris she has $1100 hidden in a paint can in the garage. He can go and take that and they'll never speak of anything that's happened again.

668* ''WesternAnimation/TheGrimAdventuresOfBillyAndMandy'': At the end of the episode "My Fair Mandy," Mandy, Billy, and Grim are [[spoiler:turned into Franchise/ThePowerpuffGirls]], sort of.

693** Years ago, Hank, Dale and Bill "borrowed" Boomhauer's car for a joyride and drove it into a flooded quarry. The three then agreed never to mention it again. Hank had no choice but to break the agreement when the quarry was about to be drained, since they left clues linking them to the case.

716** The Itchy and Scratchy Land episode, after Homer takes a disastrous shortcut:
717--->'''Homer:''' All right, we're here. Let us never speak of the shortcut again.
718*** From the same episode, when the others point out that, [[ItMakesSenseInContext despite the murderous robots]], they technically fulfilled all the conditions that Marge mentioned for a great family vacation.
719---->'''Marge:''' You know, you're right. This truly was the best vacation ever. Now let us never speak of it again.
720** Marge also said it in regard to a relative who snapped and went on a shooting spree:
721--->'''Marge:''' Well, Bart, your Uncle Arthur used to have a saying: "Shoot 'em all and let God sort 'em out". Unfortunately, one day he put his theory into practice. It took 75 Federal Marshals to bring him down. Now let's never speak of him again.
722*** And then Marge actually does speak of him again when she tells Bart to listen to his heart, and "...not the voices in your head like a certain uncle did one gray December morn."
723** This also happened in "The Principal and the Pauper", where Principal Skinner was revealed to be really an impostor named Armin Tamzarian.

The local judge issues a decree that no-one will ever mention it again, under penalty of ''torture''. [[MoodWhiplash Everybody cheers in agreement]].
724*** And, this being ''The Simpsons'', they ''do'' mention it again -- in ''I, (Annoyed Grunt)-Bot'' when Skinner is giving Lisa a hard time about naming a new cat of hers the same as her old cat, she calls him Mr. Tamzarian. On the DVDCommentary, Al Jean indicates he inserted the joke himself as a TakeThat to that episode.
725---->'''Lisa:''' I'm keeping you. You're Snowball V, but to save money on a new dish, we'll just call you Snowball II, and pretend this whole thing never happened.\
726'''Skinner:''' That's really a cheat, isn't it?\
727'''Lisa:''' I guess you're right, ''Principal Tamzarian''.\
728'''Skinner:''' ...I'll just be moving along, Lisa. Snowball II.
729** ''Another'' episode (one that's a ThreeShorts type of format like Treehouse of Horror so it's not even canon) introduces Grandpa's brother Cyrus, with dialogue to this effect (paraphrasing):
730--->'''Bart and Lisa:''' You never told us you had a brother, grandpa.\
731'''Grandpa:''' Yes, and I'll never speak of him again.
732** In "[[Recap/TheSimpsonsS28E9TheLastTractionHero The Last Traction Hero]]", Mr. Burns is revealed to Smithers and the viewers as the owner of UsefulNotes/{{Chernobyl}}'s power plant. He doesn't want the fact to be spoken of again.

737* ''WesternAnimation/StarWarsRebels'': In "[[Recap/StarWarsRebelsS2E15TheHonorableOnes The Honorable Ones]]", Zeb and Agent Kallus are [[EnemyMine forced to work together]] to escape the ice moon Bahryn after an escape pod crash. At first, Zeb offers to take Kallus as a fairly treated prisoner. Instead, they decide to get rescued separately, and as a matter of principle, whatever experiences they had do ''not'' leave Bahryn. [[spoiler:However, in season 3, these events proved too impactful for either of them to ignore; the rest of the ''Ghost'' crew, as well as some other characters, end up finding out what happened, because the events on Bahryn ended up leading to Kallus having a HeelFaceTurn.]]
738* ''WesternAnimation/StaticShock'': In "Junior", when a ship is sinking, Static tries to lift it, but he's not strong enough. He carries the passengers to shore in a makeshift raft and asks them not to tell anyone he tried to lift the ship.

740** "[[Recap/StevenUniverseS1E29SecretTeam Secret Team]]" has Steven, Pearl, and Amethyst creating a team in order to hide something from Garnet. After they destroyed all the monsters Pearl and Amethyst decide to never discuss it again, though Steven is attached to the concept of their "secret team" and ends up telling Garnet the secret.
741** "[[Recap/StevenUniverseS5E1StuckTogether Stuck Together]]": Aquamarine offers this to Topaz after the latter betrays her.
742** "[[Recap/StevenUniverseS5E18ASinglePaleRose A Single Pale Rose]]" has a more [[PlayedForDrama dramatic]] example. [[spoiler:Pink Diamond, before [[FakingTheDead staging her shattering]], orders Pearl (disguising herself as Rose Quartz) to never speak of it again. As [[ServantRace Pearl's]] obedience to her Diamond is hard-coded into her, the order functions as a {{Geas}}, leaving her TongueTied every time she attempts to talk about it.]]
743* In one crossover between ''[[WesternAnimation/TeenageMutantNinjaTurtles2003 Teenage Mutant Ninja Turtles]]'' and ''ComicBook/UsagiYojimbo'', Usagi says this when he and Leonardo infiltrate a fortress. While Usagi respects the Turtles, he doesn't really like ninjas.

751[[folder:Real Life]]
752* A key component to the treaty that ended the UsefulNotes/ThirtyYearsWar was the agreement for neither side to ever blame the other for starting it (so that it does not break out again over the debate), which effectively silenced the topic altogether in interconfessional meetings. The Westphalian mindset that wars can break out with nobody at fault remained dominant in Europe until the [[UsefulNotes/WorldWarI Treaty of Versailles]].
