Philip Marlowe: You wanna tell me now?
Vivian: Tell you what?
Philip Marlowe: What it is you're trying to find out. You know, it's a funny thing. You're trying to find out what your father hired me to find out, and I'm trying to find out why you want to find out.
Vivian: You could go on forever, couldn't you? Anyway it'll give us something to talk about next time we meet.
Philip Marlowe: Among other things.
