Sam: Look what I found in this dirty old glass.
Rebecca: Oh! Oh! Oh! You are such an angel! Oh, how can I ever thank you?
Sam: I think the how has already been established. We're up to where and how often.
Rebecca: Well... a promise is a promise.
Sam: Come on. I hate that. I hate it when you do that. Come on. What- What's wrong with you? Why- Why don't you want me? What's the problem?
Rebecca: You know, Sam, I really... I just don't know why I don't want you.
Sam: Well, think, damn it!
Rebecca: I think it's just one of those things that, when you first meet a guy, you put him in one of three categories: yes, no or maybe. And the second I saw you, I threw you right in that "no" category, and that's where you've stayed ever since. I mean, when Sam Malone walks into a room, I say "no" and go on with my life.
Sam: Every single time?
Rebecca: No. There was this one time, when you were way down at the end of the hall, and I could just see this tiny little piece of your elbow, and I didn't know for sure if it was you. And I thought to myself, hmm. And then you came around the corner, and I thought, "God, no!"
Sam: "God, no" is a lot worse than just no, isn't it?
