Jake Barnes: [Answering Robert's questions about Lady Brett Ashley] Well, let me give you the facts. She's a drunk and a drifter. She's gonna marry a guy named Mike Campbell. That way she'll have a rich, sodden old age.
Robert Cohn: I don't believe it!
Jake Barnes: Don't ask a lot of fool questions if you don't like the answers.
Robert Cohn: Well, I didn't ask you for a rundown on her private life.
Jake Barnes: You asked me what I knew about her.
Robert Cohn: I didn't ask you to insult her.
Jake Barnes: Oh, go to Hell!
Robert Cohn: Take that back!
Jake Barnes: Cut out the prep school stuff, Robert!
Robert Cohn: Take it back!
Jake Barnes: Sure, sure. I never heard of Brett Ashley. How's that?
Robert Cohn: No, not that! About me going to Hell!
Jake Barnes: Don't go to Hell! Go back in the Select if that's what you want!
Robert Cohn: All right, I will!

Jake Barnes: Don't try to tell me how to live with myself! I know all about that. It's just living with other people that gets to be tough once in a while.

Jake Barnes: Everyone behaves badly given the proper chance.

Lady Brett Ashley: I never make plans.

Lady Brett Ashley: Is Zizi on your payroll, Count?
Count Mippipopolous: Not officially. I just allow him to steal from me from time to time.

Mike Campbell: [Loudly, trying to get service] Waiter! Oh, waiter! Waiter? Pssst! Tsk, tsk, tsk! Garcon! Boy!
[Laughs]
Mike Campbell: Nobody home. You know something? The service around this town is getting worse and worse every night.
[Becoming introspective]
Mike Campbell: Perhaps it's me.
[He takes a drink from a girl]
Mike Campbell: Thank you. As a matter of fact, I'm afraid it is me. Nobody seems to pay much attention to me anymore.

Mike Campbell: I should have thought you'd have loved being a steer, Robert.
Robert Cohn: What do you mean, Mike?
Mike Campbell: Well, they lead a sort of quiet life. They never say anything important, and they're always hanging around. I should have thought you'd have enjoyed that. Aren't you going to say anything?
Lady Brett Ashley: Oh, shut up, Mike!
[She pulls his beret down on his head]
