- After the first stage of the Chuunin exams in Naruto, Proctor Ibiki explained that there were two members of the test takers who served as cheating fodder for the others, which several shinobi noticed, but Naruto was not among them. However, once Ibiki explains this, Naruto acts as if he figured it out halfway through.
- In Pretty Cure All Stars DX 3, Cure Marine and Cure Rhythm start panicking when Cure White, Cure Egret, Cure Mint, Cure Aqua, and Cure Berry start taunting Freezer and Frozen. When it turns out that their taunting leads the two to freeze the water they were trapped around, Marine instantly declares that it was a great plan and she knew it all along. The others don't buy it.
- In the Donald Duck comic "The Old Castle's Secret", after the "ghost" is revealed to be a guy using invisibility spray, Donald tries to claim he knew it all along (rather than being terrified out of his wits while Huey, Dewey and Louie single-handedly solved the mystery themselves). His nephews are not amused.
- Amelia Peabody and her husband Emerson both like to claim to be better at detective work than they actually are:
- In The Curse of the Pharaohs, most of the "deductions" Emerson claims to have made were actually things he had no idea about until the killer confessed.
- In The Deeds of the Disturber, Amelia gives The Summation to their assembled friends, explaining why one person and one person only could be the mastermind behind the murders. When she and Emerson are in bed together later, however, they both confess that they had both suspected the wrong person right up until The Reveal.
- Played for laughs in this video where someone plays Kirby Super Star and is terrified of Waddle Dee. A bystanding Straight Man makes some rational observations on him, all dismissed by the player as "Lies!" The friend eventually tells the player how to get Kirby to properly attack (to which the player expresses amazement), and once Waddle Dee finally dies, the player exclaims, "It worked! I'm a genius!"
- Woofer on Clue Club always brags to Wimper of how he knew who the mystery's culprit was and his modus operandi.
- In the Scooby-Doo, Where Are You! episode "Never Ape an Ape Man", Shaggy gets "grabbed" by a stuffed ape. Upon being told this, he says, "Well, I certainly hope you don't think he had me fooled for a minute. I knew it all the time." Scooby sees right through him.
