* At the end of ''Manga/RurouniKenshin'', [[spoiler: Enishi and his father, whom we only know as "oibore"]], run into each other in the hobo camp and have the vaguest feeling that they may know each other, but neither thinks anything of it (or [[spoiler: oibore]] just decided to not reveal himself).

* ''FanFic/LiveAHeroMHA''; Izuku wonders this of Tenya Iida when they first meet after they get accepted into U.A. This is because Tenya's older brother, Tensei, was the Pro-Hero that rescued Izuku when he escaped from the League of Villains six years prior

* ''Fanfic/TheVolatileverse'' has Jason Todd starting unaware he was dimentionally displaced when he catches a glimpse of Batman and Robin, so the vigilante really wonders why the new Boy Wonder feels familiar. The world-hopping comes to light with the reveal that Robin is actually his predecessor Dick Grayson, here thirteen years old.

* ''WesternAnimation/MadagascarEscape2Africa'', After seeing Zuba, his dad, for the first time since he was a cub, Alex, who could't remember him because he spent most of his life in New York, said this to Zuba:
-->'''Alex the Lion:''' You look familiar, Do I know you.

-->'''Captain Jack Sparrow:''' You look somewhat familiar, have I threatened you before?

* In the first episode of ''Anime/MartianSuccessorNadesico'' Yurika runs into Akito and asks if she's met him before. Akito says that they've never met, not realizing until Yurika has left that she's the girl he was friends with as a child.

* ''Film/PiratesOfTheCaribbeanTheCurseOfTheBlackPearl'': This is Jack's reaction to seeing Will. They ''haven't'' met before, but he [[spoiler: he knew Will's father.]]

* ''Film/Ronin'': Lampshaded when the pack of hired mercenaries are assembled for their first job briefing, and Spence (Sean Bean), meets the older and obviously more experienced operator Sam (Robert De Niro), and asks "Do I know you?" Sam replies dryly: "I don't think so. I'd remember." This seemingly throwaway character line later gains a lot more meaning when [[spoiler: we find out that Spence is a poseur who doesn't belong with the rest of the team, and Sam is the one to out him and humiliate him, de facto placing himself in charge of the operation.]] The question and the answer both ascend to the status of {{Arc Words}} by the end of the film, as numerous variations occur throughout. The trope is also played straight later in another classic character moment for Gene Reno's Vincent:

Again a slight variation is employed again with Sam calling out to a "friend from highschool" [[spoiler: fellow CIA operative and former or even current colleague]]" on the street, asking for directions:

The film gives us the tiniest shred of doubt that Sam doesn't know Spence from the beginning, when Sam has this early exchange with his French counterpart Vincent, who suspects [[spoiler:Sam's status as a CIA operative.]]:
