During a recorded conversation between authors C.S. Lewis, Kingsley Amis, and Brian Aldiss, Lewis is talking about science fiction when he abruptly changes the subject:
Lewis: … Are you looking for an ashtray? Use the carpet.
Amis: I was looking for the Scotch, actually.
Lewis: Oh, yes, do, I beg your pardon.
