You Do NOT Want to Know

Everything About Fiction You Never Wanted to Know.

"Trust me on this: you don't wanna know. Audrey? Don't tell him. You shouldn't've told me, but you did, and now I'm telling you, you don't wanna know!"

Joshua Sweet on Mole's past in Atlantis: The Lost Empire

Some secret about Character A is mentioned, either by the character himself, or by somebody else. When queried, someone replies "You don't want to know. Just trust me on this." Or words to that effect. Whether we actually find out what it is varies - if we don't, it can turn into a Noodle Incident, and might be set up for one or more un-reveals. The characters who do know will usually try to avoid talking about it. More often than not, this phrase can just end up as Schmuck Bait.

In other cases, we do find out. If played for comedy, the secret will turn out to be relatively innocuous - or at least, not nearly as far-out as what the other characters - and probably the audience - have imagined it might be. If played for drama (as in horror movies) it'll turn out that the secret is, indeed, quite bad, and that the others would, in fact, have been better off not knowing.

A Genre Savvy person can start to ask, and then conclude that no, they're better off not knowing. If curiosity gets the best of them, it will be followed with "I'm afraid to ask, but..."

And sometimes, it's just Too Much Information.

Other stock phrases include "I don't want to know, but at the same time, I really want to know...", "That means you do not want to know, trust me.", and "Don't Ask".

If said by a mentor, it is likely to be an Awful Truth. If they experience enough such events, leads to a character who has Seen It All.

Not to be confused with These Are Things Man Was Not Meant to Know... even if, in some cases there may be some overlap.

Examples of You Do NOT Want to Know include:

Anime and Manga

  • In One Piece. the closest the Straw Hats came to learning what Gol D. Roger's eponymous treasure was or where it is came during the Sabaody Archipelago Arc when Usopp tried to ask Silvers Rayleigh about it. Luffy angrily interrupted, indicating that he did not under any circumstances want to simply be told about it, stating that such knowledge would defeat their purpose. It seems likely that someone will eventually find out what One Piece is, but it won't be that easy.

Mal: Kaylee, find something for the doc to do. He don't need to be fussin' the whole time we're gone.
Kaylee: He and I can–
Mal: I don't want to know. Some things I really, really don't need to hear, little Kaylee.
Kaylee: I was gonna say 'we can finish up some repairs in the kitchen'. Why, what did you think I was gonna say?


  • Used for an extended gag in Atlantis: The Lost Empire, when Milo asks Audrey about the backstory of Gaetan 'Mole' Moliere, after having heard the backgrounds of the rest of the cast. She's just opened her mouth when Dr. Sweet delivers the page quote. Seeing as Moliere is a short, creepy French dude obsessed with soil and rock, not to mention an intense aversion to bathtime,[1] he may be right.
    • In the sequel, Milo say that he thinks Moliere was raised by naked mole rats. Of course, given that it went Direct to Video...
      • In an issue of Disney Adventures, it was stated that he spent most of his childhood exploring in the sewers of Paris.
  • The third Jurassic Park movie, when Alan Grant discovers the missing kid has collected a jar of Tyrannosaur urine, the smell of which scares most dinosaurs away. How? You don't wanna know.

Egg Shen: "Lo-Pan's spy. What it sees, Lo-Pan knows!"
Jack Burton: "I said, 'don't tell me!'"

  • Used as a joke in UHF:

Stanley: (Scratches head in confusion) Then why'd I ask?

  • An exchange in Free Enterprise has an imaginary William Shatner talking with a young version of Robert, one of the main characters, during a fight he got into while wearing a TOS gold uniform. When prompted Young Robert reveals it was he that started the fight.

William Shatner: What'd he say?

William Shatner: Kick the little fucker's ass.

Falcone: And the rabbits go to the man in the narrows.
Flass:: What's the difference?
Falcone: Ignorance is bliss, my friend. Don't burden yourself with the secrets of scary people.

  • The Lion King has Simba, when questioned by Timon as to why he is depressed, stating "I'd rather not talk about it." Of course, it's technically a subversion as the audience had seen beforehand why he was depressed, as he had been led to believe that he was responsible for his father, Mufasa's death.


"I could say twelve words, and when I was done, the least you'd do is turn away and leave me alone forever."
He could tell that she was speaking the truth, and the fact that she had the power to do this, to send him away, dismayed him. "Then don't say them."

  • Later:

Myn Donos: "I want to make you smile with something other than a wisecrack. I want to know who you really are."
Her laugh, sudden and hard, startled him. "Oh, no, you don't."

  • In Starfighters of Adumar, a later entry in the X Wing Series, Wedge's young guide falls for him and starts acting strangely.

Hobbie: "Not one of my languages, Wedge."
Wes: "I understood her, boss. But you don't want to know. Trust me on this."
(Wedge insists, and Wes ends up giving a very accurate, very logical explanation to the girl's behavior. Then…)
Wedge: "Wes, you were right. I did not want to know."

  • The Outcast of Redwall features a hare nicknamed Jodd. His full name results in this trope, and in the end we only hear part of it. According to the official website's "Ask Brian" feature, it's ""Wilthurio Longbarrow Sackfirth Toxophola Fedlric Fritillary Wilfrand Hurdleframe Longarrow Leawelt Pugnacio Cinnabar Hillwether Jodrellio".
  • The Golden Globe by John Varley averts Forbidden Fruit in this regard: to show that you don't want to know how Charonians have sex, you're given a description of their coming-of-age ceremony. For context, Charonians regenerate quickly and worship pain, and the ceremony itself is either Narm or Nausea Fuel.
  • Discworld:
    • Used in Thud! when Vimes asks about the worst of dwarven signs, the Summoning Dark, and is informs he does not want to know. When he asks again, he's told that no, he really doesn't. He starts to ask again before deciding that in fact that's correct, it's mystical stuff that he doesn't believe in, and drops it.
    • In Going Postal the ancient messenger golem Anghammarad recounts his motto:

Anghammarad: "Neither Deluge Nor Ice Storm Nor The Black Silence Of The Netherhells Shall Stay These Messengers About Their Sacred Business. Do Not Ask Us About Sabre-Tooth Tigers, Tar Pits, Big Green Things With Teeth Or The Goddess Czol." [...]
Moist: "The goddess Czol?"
Anghammarad: "Do Not Ask."

  • Similarly, the modern post office declares that neither sleet nor snow nor gloom of night shall stay these messengers about their business, with it's own "don't arsk us about" list. Mrs. Cake appears twice.
  • The Lemony Narrator does this to the reader in Thief of Time, when Famine talks about his love of salad cream sandwiches. A footnote advises readers from societies where the traditional condiment for salad is mayonnaise not to even ask.
  • Subverted and inverted early on in The Hitchhiker's Guide to the Galaxy, when Arthur takes the precaution of asking Ford, "if I were to ask you where the hell we were, would I regret it?" Ford cuts to the chase and tells him where they are. Arthur was probably happier when he didn't know.
  • Used in a decidedly non-comedic fashion in Memory, Sorrow, and Thorn, when Shell Shocked Senior Camaris refuses to tell the protagonists about his mysterious past that led to a Heroic BSOD, on the grounds that it's too shameful. He does confess it twice, once to a priest and once to Prince Josua, and both emerge from the experience wishing they hadn't been told. At the end, it's revealed that he's Josua's father, and lived his life afterwards in misery over his weakness and the subsequent Death by Childbirth of the woman in question.
  • During a Doctor Who short story, a skeleton grabs the Tenth Doctor by the ankle as it claws its way out of the earth. The Doctor, not taking his eyes off Rose, asks if he should look. She shakes her head.

  • In The Dresden Files novel Death Masks, Dresden finds himself having a conversation with his friend Michael's teenage daughter Molly, after escaping a situation that left him with handcuffs danging from one wrist. During their talk, Molly produces an entire set of handcuff keyes and finds one that matches the cuffs he's wearing. When Harry asks how she got the keys, she tells him to ask himself if he really wants to know the answer to that question. Harry decides he doesn't.
    • Repeated with the medical pinwheel thing. Apparently they have recreational uses. Molly used to hang out with a weird crowd. Harry decides to not pursue that line of reasoning.
    • Harry tells a bunch of his friends this about the magical world. Eventually, he gives them the option to learn anyway and stand with him. They each take it.

Live Action TV

  • In an episode of Blackadder the Third, a French torturer tells the soldier guarding Blackadder and Baldrick that he should leave, since what she is going to do will be so horrifying. He states his belief that he can stomach it, to the hag's increasingly frantic protests, until he asks for a description. She whispers to him, and of course he runs off about to vomit.
    • Also in Blackadder the Third, when Prince George describes what the Naughty Hellfire Club does to people who don't pay their dues:

Prince George: They pull your breeches down and push a large radish right up your--
Blackadder: --yes! Yes! Yes! All right!...There's no need to hammer it home.
Prince George: As a matter of fact, they do often have to--
Blackadder: --No! NO!

  • On the Raquel Welch episode of The Muppet Show, Marvin Suggs reveals to Kermit that he has to replace his living musical instruments, the Muppaphones, when they go flat (like little pancakes). What happens to them then? Well...
    • At one point, he actually was the replacement...turns out that singing the Witch Doctor song when you've been told never to tell anyone is a bad idea.
  • Red Dwarf: Lister opens a secure door and doesn't want Kryten to see how: "Trust me, you don't want to know!". Kryten doesn't look, but of course, being a robot, he correctly guesses the logical answer: Lister used a severed hand from one of the dead crew on the palm print reader.

Kryten: Logically, sir, there is only one way you could possibly have opened that door. I feel quite nauseous. Where is it?
Lister: Where's what?
Kryten: Oh, sir!! You've got it in your jacket!!

    • Subverted in Thanks For The Memory. A drunken Rimmer wants to tell Lister how many times he's made love, to which Lister replies: "I don't wanna know! Trust me, You do not want to tell me!"
      • Rimmer does, of course, and the answer turns out to be embarrassing.
    • In Backwards, before they leave, Lister tells Rimmer that Cat has gone off into the bushes, then he realizes what this entails, and says, "We've got to stop him!" Cat comes back, hair sticking straight up, walking stiffly, horrified expression on his face, and simply says "Don't ask." (For those who don't recall the episode, they were on an alternate Earth where everything happened in reverse...)
  • Used in the first-season Star Trek: The Next Generation episode "The Big Goodbye", where the fate the insectoid Jarada visit upon people who pronounce their ceremonial greeting wrong is so horrible that the crew won't even let Data hint at it.
  • In Star Trek: Deep Space Nine, Worf is asked at a party what Klingons dream about.

Worf (in Sincerity Mode): "Things that would send cold chills down your spine, and wake you in the middle of the night. No, it is better that you do not know. Excuse me." *shambles away*

    • In "Sacrifice of Angels", O'Brien and Bashir have been quoting "The Charge of the Light Brigade" in the runup to a battle where they're seriously outnumbered. Garak, eventually, asks how it ends. O'Brien tells him he doesn't want to know...which pretty much answers the question.
  • Speaking of insectoids, on an episode of Star Trek: Enterprise, Captain Archer is in VERY tense negotiations with the Xindi; his linguist Lt. Sato performs simultaneous translation—except at one point, where the insectoid goes on a long chittering rant, and Sato simply says "You don't want to know."
    • This is the second time she uses the line. In the pilot episode, a Klingon says something to Captain Archer, who takes it as a thank you. When Sato comments that she doesn't think they have a word for thank you, and Archer asks her what the Klingon did say, she responds with the line verbatim.
  • Used for comic effect in Black Books. Manny says that something bad happens to him at 88 degrees, and Bernard wants to know what, but Manny keeps repeating, "You don't want to know." Bernard at first tells Manny to stop saying that, because he wants to know even more if he's told he doesn't. Then he switches tactics, saying that Manny doesn't know WHY Bernard wants to know. To which Manny replies, "Oh, why's that?" And Bernard has made his point.
  • When a couple came into Night Court who were well known for their outlandish bad luck (the squad car they were arrested in got hit by a bolt of lightning) mention that their granny died, Harry, Dan, and Christine give each other looks before Christine bursts out "Oh what the Hell someone has to ask! How did she die?" They reply that she died peacefully while sleeping... on the railroad tracks.
  • In one episode of The Big Bang Theory, after Leonard's mother and got drunk with Penny and kissed Sheldon, she apologises to Sheldon "about her behaviour" while Leonard is present. Leonard enquires about details, but his mother, Penny and Sheldon all answer that he doesn't want to know.
  • Northern Exposure—In "The Russian Flu," Dr. Fleischman asks Marilyn what's in a foul-smelling (but effective) Native American flu remedy. Her reply: "You don't wanna know."
  • Heroes season three demonstrates how not to do this: a character whose power is treated as a "you don't wanna know" situation turns out to be something pretty basic: your typical sonic scream thing, and not even (that we saw) to Black Bolt-esque mega-destructive levels.
    • Said power was originally intended to be terrakinesis, on par with the Big Bad of volume five, but was cut due to budget restraints at the time.
  • In the Doctor Who episode "Bad Wolf", this is Jack Harkness's response when his captors demand to know how he managed to pull a concealed weapon on them despite being stripped naked.
  • On the U.S. version of The Office, Dwight issues Jim a demerit for tardiness, then explains his made-up, incredibly convoluted warning system for policing the office that, as Jim points out, logically ends with Dwight submitting a disciplinary review to his immediate superior (Jim himself, the Assistant Regional Manager). Jim responds by demanding the review be on his desk by the end of the day, or Dwight will be issued a "full dissadulation." What is that? "You don't want to know."
  • Get Smart used a variation of this in Catch Phrase fashion:

Maxwell Smart: Don't tell me [rest of sentence]
Other character: [repeats the rest of the sentence back to him]
Smart: I asked you not to tell me that.

  • A variant was used in Season 3 of Babylon 5...

Marcus Cole: They taught me…terror. How to use it. How to face it.
Dr. Franklin: I think I'd like to hear more about that…
Marcus Cole: No. You wouldn't.

    • A straighter example in Season 4 provides a Crowning Moment of Funny. Susan Ivanova stumbles litter-strewn out of a transport tube, using a cane to stay upright.

John Sheridan: What the…?
Susan Ivanova: Don't…even…ask.

  • In the Monk episode "Mr. Monk and the Miracle", Monk tells Natalie that her getting gravy wouldn't have been necessary as the bums, their guests, make their own gravy. When Natalie asks how they do it, Monk simply responds with "You don't want to know..."
    • Similarly, in "Mr. Monk Is On The Run: Part 1", after Monk arrives back at Natalie's house with a strange overcoat, he said a homeless person gave it to him in exchange for something else in return. When questioned by Natalie about what that thing was that Monk had to do, Monk can only respond with "I'd rather not talk about it..."
  • Person of Interest: in the episode "Cura Te Ipsum"

Reese: Doctor has everything she needs to erase Benton for good.

Liz: Where'd he get the bucket of cherry syrup?
Jon: Some things are better left unknown...

  • In Warcraft III: The Frozen Throne, Illidan uses this line on Malfurion.

  • In an episode of the ongoing Hercules series, the water of the Spring of Canathus turns Hercules, Icarus, Pegasus, Adonis, and Hades' minion Pain into infants, which results in Cassandra and Hades other minion Panic becoming Badly-Battered Babysitters for the rest of the episode. When the curse is finally undone, Hades shows up, and at first, he asks why everyone is wearing diapers, but then he changes his mind and says he doesn't want to know, and leaves with his two servants. However, Hercules and his friends do want to know what happened, and after Cassandra tells them, they all beg and plead with her not to tell anyone.
  • In an episode of The Grim Adventures of Billy & Mandy, Grim gives Billy a gumball machine that yields a limitless amount of gum, but warns him never to swallow the gum. When asked what will happen if he does, Grim says, "Trust me, you don't wanna know. If I had skin, it would be crawling." Billy eventually ignores this warning, and we find out that swallowing the gum causes "an unimaginably horrible rash from another dimension." Though Billy initially has bubbles and gum coming out of his body before it actually happens. The rash was what it said on the label.
  • In the Droopy cartoon "The Three Little Pups", Droopy is watching television with his two brothers in one scene; Wolfie tries to suck them up with a giant straw, only to grab the television instead (and end up with it lodged in his stomach). Two scenes later, Droopy and his brothers are watching television again, and Droopy looks at the camera and says, "Now don't ask us how we got the television set back..."
  • In one Crossover episode of Static Shock, a time-share Batman take-off villain accidentally sends Static into a future time, where he meets both Terry McGinnis (aka Batman Beyond) and the aged Bruce Wayne, along with his future self. At the end of the episode, he returns to his own time and is about to reveal to Batman what his future is like, but Batman interrupts him, saying that he'd "rather not know".
  • Regarding Niffty's backstory in Hazbin Hotel (which unlike every other character, has not been touched upon even once), Husk advises against asking, claiming, "You don't wanna know what her deal is."

Real Life

Alice: Hey, Bob... Oh, it doesn't matter.
Bob: What?
Alice: *uses this trope*
Bob: No, go on, tell me.
(Alice's muddy hands go in Bob's face)

  • How 75-year-old Sally from America's Got Talent Portland discovered she could hand-whistle. She wrote a book about it, but part of the book was also about her coming out.
    • Judging by how the judges on the show reacted ('mm-hmm'-ing and nodding), they evidently didn't consider the above to be an example of the trope. It could be a bit of a Mood Whiplash, though.
  1. which Sweet conveniently often uses on Mole during their first meeting when Mole went ballistic on Milo for unknowingly ruining his soil collection by lying on the bunk
  2. Stan is absolutely right: you don't.
  3. moreso the latter, not having been around the gang for as long as the former
