Quote from Martin in Deathtrap
Frasier: Oh, Mr. Lasskopf. So good to see you again. It's been a long time. Mr. Lasskopf: What has? Niles: We used to rent this house from you. Frasier: Yes. Niles: Uh, I'm Niles Crane, this is my brother, Frasier, and our dad. Do you remember? Mr. Lasskopf: [looking at Frasier] Nope. [at Niles] Nope. [at Martin] You sort of look familiar. Martin: Yeah, I should. I paid you rent for ten years, left the place in perfect condition, and you never gave me back my security deposit. Mr. Lasskopf: Nope. Don't remember you either.
