Frasier: Dad, you know, I'm sorry about your friend's funeral not going so well. Rest assured, when the time comes, years from now, Niles and I will follow your wishes to the letter.
Martin: Thank you.
Niles: By the way, Dad, what are your wishes?
Martin: Never mind, I'm not going to go planning my own funeral, it's bad luck.
Frasier: But, Dad...
Martin: Ah, ah, ah. You don't pull the cord on the bus until you're ready to get off. [exits]
Niles: Pull the what on the what?
Frasier: I don't know.
