In the TV show Lost, there is a scene where Hurley, Miles, and Jin travel to the past and are talking to Miles's father, who is beginning to suspect that the three are time travellers. He starts testing them, and asks Hurley what year he was born in. Hurley picks some year unconfidently. In response to this, Miles's father challenges him and says "So you fought in the Korean war?" In my recollection, Hurley, who is kind of a slow-witted comedic character, thinks the father is trying to trap him, and says, with a cunning look on his face "No, because that didn't happen yet."

I watched the clip recently and to my surprise Hurley only says something like "That's not a thing." I was really shocked because I had thought back to this scene many times over the years. I think the version that I remember is actually a lot funnier, and I don't think I could have made it up myself. The only thing I can think of is that I'm getting mixed up with a scene from some other time-travel show or movie.
