Rick: Why did you come back? To tell me why you ran out on me at the railway station?
Ilsa: ...Yes.
Rick: Well, you can tell me now. I'm reasonably sober.

Willie Stark: Jack, there's something on everybody. Man is conceived in sin and born in corruption. He passes from the stink of the dydie to the stench of the shroud. There's ALWAYS something.

Addison DeWitt: Is it possible, is it even conceivable, that you've confused me with that gang of backward children you play tricks on?

Margo Channing: I detest cheap sentiment.

Isabella: If Cathy died... I might begin to live.

Dreyfus: If someone has been murdered here, please let it be Clouseau.

Longfellow Deeds: When the servant comes in, Mr. Hallor, I'm going to ask him to show you to the door. Many people don't know where it is.

Devlin: I can't help recalling some of your remarks about being a new woman. Daisies and buttercups, wasn't it?
Alicia: You idiot! What are you sore about, you knew very well what I was doing!
Devlin: Did I?
Alicia: You could have stopped me with one word, but no, you wouldn't. You threw me at him!
Devlin: I threw you at nobody.
Alicia: Didn't you tell me what I had?
Devlin: A man doesn't tell a woman what to do; she tells herself. You almost had me believing in that little hokey-pokey miracle of yours, that a woman like you could change her spots.
Alicia: Oh, you're rotten.
Devlin: That's why I didn't try to stop you. The answer had to come from you.
Alicia: I see. Some kind of love test.
Devlin: That's right.

Bill Sampson: We started talking - she wanted to know about Hollywood. She seemed so interested.
Margo Channing: She's a girl of so many interests.
Bill Sampson: Pretty rare quality these days.
Margo Channing: A girl of so many rare qualities.
Bill Sampson: So she seems.
Margo Channing: So you've pointed out so often! So many qualities so often - her loyalty, efficiency, devotion, warmth, and affection, and so young! So young and so fair!

[to Preysing, after he tries to get 'familiar' with her by asking her to call him by his first name]
Flaemmchen: You know I always say that nothing should be left hanging over. And names are like that. Suppose I met you next year and said, 'How do you do Mr. Preysing?' And you said, 'That's the young lady who was my secretary in Manchester.' That's all quite propper. But supposing I saw you and yelled 'Hi baby. Remember Manchester.'
[he laughs]
Flaemmchen: Yeah, and you were with your wife. How would you like that?
