I'll Never Tell You What I'm Telling You

"Nazi Captain: Your name vill also go on ze list! What is it?

Captain Mainwaring: Don't tell him, Pike!"

- Dads Army

This is when someone -- usually a villain -- grabs hold of the Idiot Ball, and denies information in such a fashion that states exactly what is allegedly being denied. For example, Alice has defeated Bob, The Dragon, whose boss has kidnapped Carol. Alice demands to know where Carol is, but Bob just smirks at her and says, "Ha! I'll never tell you that she's in the warehouse in Somewhere City!"

A sort of Accidental Public Confession, with a little Suspiciously Specific Denial thrown in for good measure. If the person is doing this deliberately, it's Could Say It, But.... Or it could be that the villain has a gun in his face and he's a coward. If the person saying this is not a complete moron, he may follow it with "Did I Just Say That Out Loud?" Also related to You Just Told Me. Truth Serums in fiction have been known to cause this. Compare Cannot Keep a Secret and Loose Lips. sub trope of Saying Too Much

Comic Books
"Mxyzptlk: You make me say, spell, or otherwise reveal my name backwards and I'll split until our dimensions come into alignment again in about, oh, three months, give or take.
 * The very first appearance of Mr. Mxyzptlk in the comic book Superman is a textbook example of this trope, when the imp declares, "Ha! You thought you could trick me into telling you that the magic word is 'Kltpzyxm'!"(poof). Also played with in the animated series:

Superman: I can't even say your name forwards. How am I supposed to say it backwards?

Mxyzptlk: No, dope! You don't have to say it backwards! You've got to get me to say it!

Superman: Say what?

Mxyzptlk: KLTPZYXM! Gosh, you're thick! Now, for the last time... (realizes) ahh nuts! (disappears)

(ninety days later)

Mxyzptlk: (reappearing in the bathroom mirror) Hi guy! Your three months are up, and this time, you're not gonna cheat me out of my fun!

Superman: Oh, it's you again, Mr. Kltpzyxm.

Mxyzptlk: Not "Kltpzyxm"! Mxyztplk! Now the first thing I'm gonna do... ahh nuts! (poof!)"


 * ...and so on and so on... Eventually reached the height of awesome when Mxyztplk showed up, screwed up, and poofed without Superman saying a word. All he does is smile... and continue drinking his coffee.

"Lusene: Zat would be ze greatest crime in histoire, non? But... Ah 'ave no idea what ze Black Knight plans to do... tomorrow morning at 10AM! Here! Pass zese out!
 * Done by the title Gentleman Thief in Don Rosa's Scrooge McDuck-story The Black Knight Glorps Again, not out of stupidity, but sheer ballsiness. In his civilian persona of playboy millionaire Arpin Lusene he gives the following statement to the press:

(passes a written program of the caper's details)"

"Thomson or Thompson: No, our lips are sealed. We can't tell you whom we suspect, but it isn't anyone in the house. Mum's the word, you know.
 * Thompson and Thomson from the Tintin series do this a lot. An example from The Castafiore Emerald:

Thompson or Thomson: Yes, dumb's the word, that's our motto. So we're not allowed to tell you about the gypsies, though we suspected them from the start..."


 * In one story of Monica's Gang, Smudge (Cascão) had his right arm in a cast and Jimmy Five (Cebolinha) wrote on it that Monica was short, fat and buck-toothed.

Literature
"Swan: Thought you'd got me there, didn't you. Thought you'd tricked me, eh? Thought I might unthinkingly give you a couple of bars of the Pedlar's song from Lohenshaak, eh?
 * Harry Potter's Hagrid in the book version too, just without the catchphrase. For example, the heroes that are looking for info on the Sorcerer's/Philosopher's Stone, and Hagrid tells them that they should give up and the only people who need to worry about the Stone are Dumbledore and Nicolas Flamel... when they didn't know about Flamel yet. In Hagrid's defense he had downed a few pints earlier...
 * In a variant, the Death of Discworld once tricked a swan into singing its "swan song", a necessary prerequisite before it could die, using this trope:

Death:

Swan: That's the one that goes "Schneide meinen eigenen Hals--"

Death:

Swan's ghost: Bugger!"

"Rachel: Louis, we can't afford... you can't afford...
 * In Stephen King's Pet Sematary, when Louis buys Rachel a sapphire necklace for Christmas:

Louis: I socked some money away off and on since last Christmas... and it wasn't as much as you might think.

Rachel: How much was it?

Louis: I'll never tell you that, Rachel. An army of Chinese torturers couldn't get it out of me. Two thousand dollars."

Live-Action TV
""I'm not going to tell you my name. Because when you tell someone your name, you give them power over you. Like if you said, 'Ron,' I'd say 'What?' And no-one's going to have that kind of power over Ron Shaffer!""
 * A Mad TV sketch has the following exchange:

"Queen: Do I tell people that your brother is afraid of spoons? Or that your father has very small private parts?"
 * Blackadder
 * Blackadder I: The queen insists she can keep the secret of Prince Edmund oversleeping and missing the battle altogether:

""Don't tell him, Pike!""
 * Blackadder Goes Forth: Baldrick and George, denying that Captain Blackadder shot the pigeon. General Melchett's pigeon.
 * And in Blackadder's Christmas Carol prince Albert does this repeatedly, when not tellinq queen Victoria about his surprise presents.

 * In the functional finale of Beetleborgs Metallix,
 * Dads Army, regarding Pike's name:

"Cyberman:
 * A particularly clunky example occurs in a second-season episode of Lie to Me: a guy suspected of killing a woman named Connie claims to not know her husband, Eric. When asked if he'd ever been to Connie's house, the suspect immediately replies, "No, I've never been to Eric's wife's house." As an inadvertent slip, it seems oddly deliberate.
 * The Daleks and Cybermen have a variation in the Doctor Who episode "Doomsday".

Dalek:

Cyberman:"

"Amsha: What he's trying to say is, we would never do anything to jeopardise your career.
 * In Star Trek: Deep Space Nine, Doctor Bashir's father comes into the public medical facility and proceeds to say to what he thinks is his son, "Don't worry, I'll never tell anyone " Slightly more of an accidental public confession, but wins extra idiot points for pretty much explicitly I'll Never Say What I'm Saying Right Now.

Richard: And just so there's no misunderstanding, I give you my word that at no time in our interview with Doctor Zimmerman will we ever mention or even hint at the fact that you were genetically enhanced as a child.

Amsha: Jules, you can trust us. Your father and I have kept the secret of your DNA resequencing for almost twenty-five years and we're not going to let it out now."

"Penny: (inside a restaurant) Look, why is it so hard for you to keep one little secret?
 * The Big Bang Theory: Sheldon Cooper is absolutely unable to keep secrets.

Sheldon: I'm constitutionally incapable. That's why I was refused clearance for a very prestigious government research fellowship at a secret military super-collider, located beneath a fake agricultural station 12.5 miles south-east of Traverse City, Michigan.

Penny: (Jaw Drop)

Sheldon: Which you did not hear about from me."

"Sheriff Carter: So... what? You're taking credit, but you had help? I'm guessing from somebody who'd want to hurt the new sheriff?
 * Top Gear parodies this. Very often they'll take their cars (supercars or otherwise) to a manufacturer's "top-secret road-testing facility" while the camera pans over the facility's address. That is, if Jeremy doesn't outright say the address himself, pausing to let the audience take notes.
 * From Eureka:

Dr. Fielding: No! ... Marguerite would never harm anyone!"

"Will: Brittany, who told you to ask these?!
 * From Glee, when Brittany is asking Will embarrassing questions.

Brittany: Miss Sylvester says I'm not at liberty to say."


 * The 1950s show House Party (redone by Bill Cosby as Kids Say the Darndest Things) was hosted by Art Linkletter, who'd interview children in hopes they'd say something amusing; one of his favorite tricks was to ask "What did your mother tell you not to say today?"
 * The Fast Show featured the character of Janine, a Dumb Blonde teenage single mother, who refuses to disclose the identity of her baby's father because "it's not fair to grass on your headmaster."

Theater
"Cyrano: I loved you not.
 * Cyrano De Bergerac: Amazingly Played for Drama at Act V Scene V, where Roxane, after fourteen years, at last realizes that Cyrano was Playing Cyrano (the whole point of the play is that Cyrano is not capable of admit her own feelings):

Roxane: You loved me not?

Cyrano: 'Twas he!

Roxane: You loved me!

Cyrano: No!

Roxane: See! how you falter now!

Cyrano: No, my sweet love, I never loved you!"

"He lives not now that knows me to be in love; yet I am in love; but a team of horse shall not pluck that from me; nor who 'tis I love; and yet 'tis a woman; but what woman, I will not tell myself; and yet 'tis a milkmaid."
 * Launce, of Two Gentlemen of Verona, does this in monologue to the audience:

Video Games
"Eggman: Did you really think you could trick me with that fake Emerald?
 * In Street Fighter Alpha 3, this is how Birdie reveals Shadoloo's headquarters to Chun Li.
 * Invoked in Batman: Arkham Asylum, when Harley Quinn says, regarding the Joker's location: "You'll never find him! He's in a  and... aw, crap!" Of course, Bats already knew, so this just served as another item on the Humiliation Conga she was currently going through.
 * In a Call Back, Harley does this once again in the second game by not telling Batman about the Freeze Tech in the boiler room, and again in the "Harley Quinn's Revenge" DLC by
 * Final Fantasy VII plays with this trope a bit, if this is the right trope; Elena doesn't exactly tell you what she's denying, but she does continue to tell you the enemy's plans verbatim after being told explicitly that she talks too much...for telling you the enemy's plans verbatim.
 * Sonic the Hedgehog
 * Deliberately invoked in Sonic Battle, where Eggman states, very loudly, "They'll never find me in Gimme Shelter!" However, Eggman was actually trying to trick Knuckles and Emerl to "follow" him to Gimme Shelter.
 * Also happens in Sonic Rush Adventure; apparently, Captain Whisker is that dumb.
 * Also happens in Sonic Adventure 2 when Eggman finally has Sonic and Tails where he wants them, and just needs the real Chaos Emerald to complete his scheme. Sonic sees through it. Tails... not so much.

Tails: So... how did you know it wasn't the real one?

Sonic: Tails!

Eggman: Because You Just Told Me, Fox Boy!"


 * To Eggman's credit, he did know there was a fake Emerald, due to him having 6 and there being 2 more aboard the ARK (and there are only seven Emeralds).

"Kyon: Sorry! Kyon's on a secret mission right now. I can't tell you my name.
 * In Paper Mario: The Thousand-Year Door, Professor Frankley says "I don't think we can trust this box. We'd better not tell it we're looking for the Crystal Stars."
 * In Super Paper Mario, Luigi announces that he'll never give his name to scoundrels like Count Bleck. Which he then immediately follows with "Now taste the wrath of Luigi!"
 * In Endless Frontier, Cute Witch Kyon does this. A lot. Usually followed by "Oops. Now I have to kill you."

Aschen: ... So, Kyon, what were you doing in a place like this?

Kyon: Wha--!? D-Did you read my mind!? Are you a psychic robot!?

Aschen: Yes."

"Alec: Don't tell me Claus went after that detestable Drago to try to...
 * In The Legend of Zelda the Wind Waker, there are two girls on Windfall Island who embody this trope. They "won't" tell you anything, not even for two Rupees!
 * And in The Legend of Zelda Phantom Hourglass, a Goron tells you that, since you're an outsider, he shouldn't tell you that the Elder's home is right over there, in this spot on your map! (Of course, the home is a big and obvious cave anyway.)
 * Shadow Hearts: Covenant
 * When Yuri and company reach Roger Bacon's house, Lenny appears to tell taunt them by saying Roger's been kidnapped. Yuri tricks Lenny into blabbing by claiming Lenny doesn't know where he's been taken, annoying him to the point where he vehemently tells them Roger's in Florence, Italy just to prove he does know. He then slumps to the ground, mouth agape, and sobs at what an idiot he's been.
 * Yuri tries the exact same trick on Veronica later on when trying to figure out where their leader, Nicolai, went. She pretends to fall for it before responding with "That's right. I don't know. What kind of idiot would fall for that stupid trick?!", making Lenny feel like a complete jackass in the process.
 * Commonly done by the villains in the Pokémon games.
 * During the tutorial in City of Villains, Operative Jenkins tells the Longbow agents that have him pinned, "I'm a trained Arachnos soldier, you won't get me to spill the name of that easy!"

Lucas: Okay. I won't. I also won't tell you he grabed Dad's knife and ran off into the mountains to try and kill the Drago.

Alec: It's a good thing you raised him to be honest, Flint."
