** ''DickTracy vs. Cueball'' (1946)

* A major plot of [[Anime/MobileFighterGGundam G Gundam]] is that Kyoji made a clone of himself with all of his knowledge and skills in order to protect his brother Domon as he was currently under the control of the Dark Gundam and incapable of helping Domon himself. When asked by Domon why he didn't reveal this secret earlier, Kyoji's clone states, "You were so hot-headed back then, Domon; you wouldn't have believed me if I had told you."

-->'''Kyon:''' (through ManlyTears) I...it's... It's nothing nearly that bad. I wouldn't... You may still think I'm crazy, and... Well, parts of this are secrets I don't really tell anyone else, but...
* In ''{{FanFic/Insomnia}}'', Link acts on this trope's principle whenever he shrugs off Tatl's attempts of uncovering his backstory.

[[folder: Film ]]

* ''[[Series/WarOfTheWorlds War Of the Worlds]]'' episode "The Resurrection"
* Used in [[BuffyTheVampireSlayer Buffy]]'s second season finale, after ''Spike'' has offered to help her prevent the apocalypse.

* ''[[Series/SoRandom So Random]]'': Rufus's CatchPhrase is "Oh, you're not going to believe this." Naturally, every word he says is true, no matter how ridiculous.
* ''{{Series/Sliders}}'' had this nearly every episode, when they had to convince people in whatever AlternateUniverse they were visiting of where they came from.

* A variation: In TheBible, Luke 22, the arrested Jesus is interrogated and asked to confirm that he claims to be the Christ. He answers with pretty much this phrase. If Our Lord being a DeadpanSnarker distresses you, wait 'til you find the puns.

* In the {{Justice League Unlimited}} episode "Double Date", Green Arrow asks [[CloudCuckoolander The Question]] why he's helping [[VigilanteMan Huntress]] track down the man who killed her parents. Question responds with this, and everyone just assumes he says it because his motives are something insane. (It turns out he's just trying to impress Huntress.)

* The player can invoke this in the game [[MissionCritical Mission: Critical]] after waking up with the first officer of the USS Lexington angry, holding a sidearm on them, and demanding answers. It goes about as well as one would expect.

* During the final level of Crysis Nomad finally meets with Psycho again, who had been supporting him throughout the game up until they were separated, and sees that he has secured an alien life-form for the U.S Navy to study. Nomad asks Psycho how he got the alien off the island and onto a Naval vessel Psycho responds saying, "Long story. You wouldn't believe me if I told you." However there was a DLC for the original PC version where we do in fact see how Psycho got it.
