Let Us Never Speak of This Again



""I cannot jump the distance, you'll have to toss me!... Don't tell the elf.""

- Gimli, The Lord of the Rings: The Two Towers

Hilarity Ensues 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. A common reply to comply with the sentiment is say something to the effect of "Speak about what again?".

This trope can be used to introduce a Noodle Incident, 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.

Subversions can occur when the character(s) kept in the dark reveal themselves to have 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 and earning the reaction "I thought we agreed to never speak of it again" or something close to that.

It can be parodied by the person(s) who are told to never mention it again is genuinely unaware of what happened for whatever reason, with them asking "Speak about what again?" getting taken by the person wanting the secret kept as a joke implying compliance with their wish.

Anime and Manga

 * Mahou Sensei Negima
 * Asuna says this to everybody after an unfortunate incident involving The World Tree that turns Negi into "the kissing Terminator" who forces her into a french kiss... for so long that she nearly suffocates. Negi is still totally unaware that this happened.
 * It happens again later under very similar circumstances, only this time the kisser was a Negi duplicate gone out of control, and the victim (and person saying it) was Akira.
 * Bleach
 * Whenever, which is a secret because he's afraid his macho buddies will disown him, since anyone in that squad whose sword isn't a direct combat type is considered a coward.
 * Also when because he's afraid of getting promoted.
 * In the Yu-Gi-Oh GX dub, Elemental Heroes Sparkman and Avian realize they were brainwashed into loving the Maiden in Love: "Guy pact -- this didn't happen, okay?"
 * During the first Yu-Gi-Oh, Kaiba sums up the Noah filler arc as a "complete waste of [his] time and effort, so let's move on and pretend that nonsense never happened."
 * Which really sounds like the sort of thing that Little Kuriboh would have made him say.
 * In the end of the first season of Pokémon, Brock decided to stay with a beautiful Professor Ivy. Two seasons later, he returns to Ash's hometown to help his mom and Prof. Oak. Somehow, the relationship ended badly for him, as any mention of her name will cause him to hide under a table or something to that extent. We never learned what happened, and he's not talking. It was never brought up again...

Comic Books

 * In Chaos War #3, while under the influence of Venus's magic song, Amadeus admits to Thor that he loves him. Thor says he loves him too, and then says not to speak of it ever again.

Fan Works
"Tsuzuki: And all's well that ends with shoujo bubbles and the acceptance of mortality. Now let us never speak of this again. Matsushita-sensei: And they never did."
 * In the Cropped Scan Theater rip of Yami no Matsuei, the first filler chapter which had no relevance to the rest of the plot was ended by this exchange:

"Yugi: Well, it's the end of the movie. All in all, it was kinda disappointing. Téa: I can't help but feel it was all just a cheap cash-in made to promote a bunch of cards. Grampa Moto: It's almost like this whole story was thrown together at the last minute. Pegasus: I agree. So, from now on, let's pretend it never happened."
 * Thereafter, every filler or otherwise irrelevant chapter was ended by the narrator saying "...And they never did."
 * Yu-Gi-Oh! The Abridged Movie gives us this exchange:

"Freeza: Oh... and all this time I could've sworn you were-- ...never mind. Zarbon: What? You thought I was single? Freeza: Well, no, I just... I thought you were into... you know, it really doesn't matter. Zarbon: Well it matters to me, because, frankly it sounds like you thought I was-- Random Minion: Lord Freeza! Vegeta's broken out of the healing--TAAAAANK! (dies by ki blast) Freeza: Oh no, that minion died. Could you go fix that? We'll continue this conversation never."
 * Freeza from Dragon Ball Z Abridged has one of these after an awkward conversation with Zarbon after the latter mentions his girlfriend.

Films -- Animation
"Diego: If anybody ever asks, there were fifty of them. And they were... rattlesnakes.""
 * Crane says this to Po in Kung Fu Panda after Crane helps him out of an uncomfortable position.
 * A variation in Ice Age 2: After Diego and Sid are easily beaten up by two possums:

Films -- Live-Action
"Admiral Greer: Now, Commander... that torpedo did NOT self-destruct. You heard it hit the hull, and I... was never here."
 * The Starsky and Hutch 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.
 * In the film version of The Lord of the Rings: The Two Towers Gimli says the above quote before having Aragorn use him in a Fastball Special (a reference to a scene in the first movie in which he objected to being thrown by Legolas). Aragorn promises not to say a word.
 * Harold & Kumar Go to White Castle, the Freakshow incident.
 * An oblique variant in Spaceballs: after watching the painful footage of being catapulted into the bulkhead of Spaceball One, Dark Helmet says "No, no. Go past this part. In fact never play this part again."
 * The Hunt for Red October. After Admiral Greer fakes the torpedoing and destruction of the Red October, he tells the torpedo control officer of the frigate he's on:

"Burt: I would prefer... we keep this... to ourselves."
 * In the end of Zathura, . They bring it up anyway.
 * Burt Gummer says this after surviving being swallowed by a Grabiod in the third Tremors movie.

"President: The following conversation never happened."
 * Wild Wild West: When Jim West gets 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."
 * A non-funny example occurs at the end of 4 Months, 3 Weeks, and 2 Days.
 * A even less funny example from Pulp Fiction. After Butch saves him from Zed's... attentions, Marsellus Wallace demands two things, of which the first is... "Don't tell nobody about this. This shit is between me, you, and Mr. Soon-to-Be-Living-the-Rest-of-His-Short-Ass-Life-in-Agonizing-Pain Rapist here. It ain't nobody else's business."
 * National Treasure: Book of Secrets has a part where Gates successfully convinces the president to tell him about the President's Secret Book, in an attempt to find the long-lost City of Gold. However, Gates is warned beforehand:

Literature

 * Discworld
 * Lords and Ladies: No one should even mention the Stick and Bucket Dance. Not ever.
 * Also in Witches Abroad, after the witches take part in it, nobody mentions the Thing With The Bulls ever, ever again. At least not around the men.
 * In Pride and Prejudice And Zombies 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.

Live-Action TV
"Matt Parkman: (after riding Nathan Petrelli to Texas) We never talk about that again."
 * Heroes. Just so there are no misunderstandings, Nathan can fly:

"Buffy: How bored were you last year? Giles: I watched Passions with Spike. Let us never speak of it again."
 * Friends
 * 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.
 * 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?!"
 * And there's the time that Monica is stung by a jellyfish. A friend who will pee on you is a friend indeed.
 * Star Trek: The Next Generation
 * The episode "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."
 * 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.
 * Subverted in that it actually is brought up again. During Data's trial to determine whether he is a full-fledged person with rights, Picard persuades him to reveal it.
 * And it's also alluded to in First Contact. Thus, there are some instances where it's treated as if the above scene wasn't cut.
 * The plot of "Clues" hinges on an instance of this trope. The Enterprise encounters a xenophobic race, the Paxans, who do not tolerate other species' knowledge of them. They incapacitate the crews of ships who come to their home planet, erasing their short-term memories and transporting the ship some distance away, leaving the crew to believe that they have encountered an unstable wormhole. Data, however, cannot be affected, and the Paxans would have destroyed the Enterprise except that Picard ordered him never to reveal what actually happened.
 * In one episode of Scrubs, Dr. Cox invokes this trope after Dr. Kelso gives an all-too-graphic description of his and Mrs. Kelso's recent sexual encounter.
 * Buffy the Vampire Slayer
 * From the episode "Real Me":

"Spike: Yeah. (beat) Tell anyone we had this conversation, I'll bite you. Andrew: Right."
 * Spike and Andrew have an exchange on their mutual love of onion blossoms while en route to a mission, ending with:

"CEO lady (spit) We will speak of it no more!"
 * 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.
 * Angel played it for laughs in the episode "The Girl in Question". The head of Wolfram and Hart's Rome branch used it several times.

"The Doctor: Please, when Torchwood comes to write my complete history, don't tell people I traveled through time and space with her mother."
 * In an episode of Would I Lie to You?, Neil Morrisey, voice of Bob the Builder, 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."
 * The West Wing Lampshaded its frequent use of of the Walk and Talk 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. Josh: "Let's not tell anyone about this."
 * Doctor Who
 * In the episode "The Shakespeare Code", two of Shakespeare's Acting Troupe agree to this after inadvertantly (and thankfully, temporarily) summoning a Carrionite while reading aloud the Words of Power inserted into the play's script by the Monster of the Week.
 * The Doctor also had one of his own when the head of Torchwood found out that the woman he'd claimed was Rose Tyler was actually Rose's mother.

"Pullo: Gods, that was something, let me tell you. Vorenus: I don't want to hear about it. If you're wise, you'll never speak of this again. Pullo: Why? I was only obeying orders. Bloody good orders, too."
 * ''The Big Bang Theory': 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."
 * In Babylon 5, after learning the secret of the 'tentacles' Londo were using to cheat at cards, Lennier decides to swear an oath of silence on the matter.
 * iCarly
 * Between the Shay siblings, notably, Carly's No Periods, Period in "iDate a Bad Boy" and Spencer's attempt at giving Carly The Talk in "iSpeed Date".
 * Sam and Freddie's agreement about their First Kiss. When Sam's drugged slip-of-tongue reveals it to Carly, Hilarity Ensues.
 * Used hilariously in Rome. Cleopatra wants to use The Baby Trap on Caesar, but knowing that Caesar has no sons, (and possibly needing a distraction from her withdrawal symptoms after Going Cold Turkey) 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 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, Pullo to "Report to Princess Cleopatra and do whatever she tells you to." Cue a prolonged and noisy bout of sex, much to the discomfort of Vorenus. When Pullo returns, they have the following conversation:

"Manny: Yes, it'll be quite some time before I want to sacrifice another monkey. (Bernard lunges forward and grabs him) Bernard: YOU SAID WE WOULDN'T TALK ABOUT CANADA!"
 * Invoked almost verbatim by Cristina in the Greys Anatomy 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.
 * Almost verbatim on The Peter Serafinowicz Show. Upon making a breakthrough deduction in a case, Sherlock Holmes, Holmes says "We shall not speak of this again."
 * One happens offscreen in Black Books, we only see Bernard's reaction when Manny breaks silence.

Recorded and Stand Up Comedy
""The old living room is a place of evil, my children. We shall speak of it no more.""
 * Arachnophobic comedian Phil Jupitus explaining that if you go to get a glass and coaster, and on your return the spider has disappeared, you can never use that room again:

Video Games
"Raz: So, is this the part where I get a speech and learn another lesson...? Sasha: No. Here is your merit badge. Let us never speak of this again."
 * Psychonauts
 * There's a Mental Phlebotinum Breakdown 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:

"Zevran: I don't mind never speaking of it again, as long as we could do it again."
 * If you return to clean up loose ends, Raz will bring it up again. Sasha will reveal that he expected Raz to overload the machine, and the course he ran was equally planned, to allow Raz to learn to use his power in practical application. The Megacensor was where things got out of hand, though.
 * Persona 3
 * The Love Hotels Incident.

 * Dawn of War II agrees with fans' opinion of the previous Soulstorm:

"Trucy: I can still remember that moment... You brandished those bloomers on high, and shouted... "Objection!" Apollo: ...Here's what I want you to do, Trucy. Take that memory, gently lock it away deep in your heart, and never speak of it."
 * In The Elder Scrolls V: Skyrim, this is, word for word, one of the dialogue choices available after you let an apprentice mage practice a spell on you.
 * Apollo Justice: Ace Attorney, case 2:

"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!"
 * Suggested in Team Fortress 2's In-Universe Marketing for Jarate.

"Belkar: Maybe we'll see that as a bonus story in one of the books! V: Maybe we shall never mention it again. Belkar: Yeah, probably that."
 * The Order of the Stick
 * While being interviewed for the Lawful Good afterlife, hero Roy Greenhilt stops the deva interviewing him before she can mention a Gender Bender incident within earshot of his father, who is standing not ten feet away.
 * 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.
 * And during Azure City's New Year, Belkar 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.

 * The Simpsons
 * The Itchy and Scratchy Land episode, after Homer takes a disastrous shortcut:

"Marge: This truly was the best vacation ever. Now let us never speak of it again."
 * Marge also used the line in the same episode. A possible subversion, as the thing to never be spoken of was actually somewhat positive:

"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 Marshalls to bring him down. Now let's never speak of him again."
 * Marge also said it in regard to a relative who snapped and went on a shooting spree:
