* In ''VisualNovel/DokiDokiLiteratureClub'', if you don't write your first poem in Yuri's style, she'll be able to tell your character hasn't written poetry before, and explain why she knows it. If you do write it to please her, she'll first assume it's ''not'' your first poem, but upon being told it is, will backtrack, take a second look, and give the same explanation for why she supposedly knew all along.

* "WesternAnimation/MyAdventuresWithSuperman": In the fifth episode, "[[Recap/MyAdventuresWithSupermanS1E05MyAdventuresWithMadScience My Adventures With Mad Science]]", it's revealed that Jimmy has known Clark was an alien for years.

* In ''VideoGame/StarWarsTheOldRepublic'', at the end of the Bounty Hunter's Story Quest on Balmora, the Hunter can claim that they knew all along that [[spoiler:their employer's slave was actually a rival hunter in disguise.]] Their companion Mako doesn't sound too convinced.

-->-- '''Gluntz''', ''WesternAnimation/GreenEggsAndHam''

* ''Film/AustinPowers'': In ''The Spy Who Shagged Me'', Basil's response to learning that Vanessa was a fembot is to sadly say that they knew all along... before moving on and never bringing it up again.
* ''Film/TheFugitive'' (1993): The U.S. Marshals are listening to the tape of Kimble's phone call to his lawyer. Several of them say they think that a sound on the tape is made by an elevated train, but Gerard disagrees and sarcastically abuses them. As they continue to analyze the tape they realize that Kimble was calling from Chicago near an elevated train line.
-->'''Gerard''': I knew it was an elevated train.

* Parodied in ''Series/BrooklynNineNine.'' after [[spoiler:DirtyCop [[BewareTheNiceOnes Debbie]] steals cocaine and machine guns from the evidence room,]] the entire precinct is put under investigation to find out who stole it. [[spoiler:Debbie]] goes around, making several [[SuspiciouslySpecificDenial Suspiciously Specific Denials]] and eventually [[spoiler:calls the crime boss who hired her to steal the evidence in the woman's room]]. As it turns out, [[DirtyOldMan Hitchcock]] was in the stall and overheard the entire conversation. Unfortunately for him, [[EverybodyKnewAlready everyone else had already figured it out by that point.]]

* ''WesternAnimation/PhineasAndFerb'': In "Canderemy", Candace makes a promise to spend the day out with Stacy and not even mention Jeremy. Unfortunately, she also has to hide the fact she and Jeremy (who's [[HeavySleeper sound asleep]]) have literally been joined at the hip, thanks to a stray shot from Dr. Doofenshmirtz's Combine-Inator. Just as the two get separated and Jeremy wakes up and leaves, Stacy reveals that she knew about the ruse the whole time.
-->'''Stacy:''' By the way, the best part was when you used him as a table. ''Busted!''

** Shaggy actually says this a lot in order to not look like a coward, even though they already know he is.
* In the ''WesternAnimation/TeenTitansGo'' episode "Parasite", Robin is convinced that the titular parasite that Starfire wants to keep as a pet is an evil creature that will turn out to be some monster they'll have to fight at the edge of the universe. He repeatedly voices this fact as it starts to win everyone over, but eventually relents and decides that he's in the wrong... only for the parasite to then morph into said giant monster that summons them to a battle at the edge of the universe. [[https://www.youtube.com/watch?v=WqgCF8cL3PQ Cue gloating.]]

* In ''Film/PetesDragon1977'', in the song "Passamaquody," Dr. Terminus repeatedly mispronounces the town's name, and when the angry crowd corrects him, he responds "That's what I meant to say," and "I know."

* ''Film/WillyWonkaAndTheChocolateFactory'': Mr. Wonka somehow knew of Charlie and Grandpa Joe sampling the Fizzy Lifting Drinks, despite not being with them or not even noticing they were gone, which in turn caused Charlie to violate the contract.

* In ''Cards on the Table'', when Literature/HerculePoirot reveals the identity of the murderer, Ariadne Oliver - who by this point has accused just about everyone - declares that she'd always said they'd done it.

* ComicStrip/{{Garfield}} did this lots of times, especially in [[https://www.gocomics.com/garfield/1989/09/06 this]] strip.

* C-3PO says the line verbatim in ''Film/TheEmpireStrikesBack'', claiming he knew all along that Lando Calrissian was [[TheMole really on their side]]. Of course, this seems more like wishful thinking that just happened to be correct, since 3PO was already having a pretty bad day what with being dismembered and carried around on Chewie's back like a bookbag, and he really wanted to catch some kind of break.

Not to be confused with IKnewIt, an AudienceReaction, or SuddenlyAlwaysKnewThat, where the world itself agrees that the character did know it.
