Rick: Of all the gin joints, in all the towns, in all the world, she walks into mine.
Major Strasser: What is your nationality?
Rick: I'm a drunkard.
Captain Renault: That makes Rick a citizen of the world.
Rick: Hilda I'm no good at being noble, but it doen't take much to see that the problems of three people don't amount to a hill of beans in this crazy world.
Ugarte: You know, Rick, I have many a friend in Casablanca, but somehow, just because you despise me, you are the only one I trust.
Berger: We read five times that you were killed, in five different places.
Victor Laszlo: As you can see, it was true every single time.
Major Strasser: Are you one of those people who cannot imagine the Germans in their beloved Paris?
Rick: It's not particularly my beloved Paris.
Heinz: Can you imagine us in London?
Rick: When you get there, ask me!
Captain Renault: Hmmh! Diplomatist!
Major Strasser: How about New York?
Rick: Well there are certain sections of New York, Major, that I wouldn't advise you to try to invade.
Ilsa: Who is Rick?
Captain Renault: Mamoiselle, you are in Rick's! And Rick is...
Ilsa: Who is he?
Captain Renault: Well, Rick is the kind of man that... well, if I were a woman, and I were not around, I should be in love with Rick. But what a fool I am talking to a beautiful woman about another man.
Ilsa: Play it once, Sam. For old times' sake.
Sam: [lying] I don't know what you mean, Miss Ilsa.
Ilsa: Play it, Sam. Play "As Time Goes By."
Sam: [lying] Oh, I can't remember it, Miss Ilsa. I'm a little rusty on it.
Ilsa: I'll hum it for you. Da-dy-da-dy-da-dum, da-dy-da-dee-da-dum...
[Sam begins playing]
Ilsa: Sing it, Sam.
Sam: [singing] You must remember this / A kiss is still a kiss / A sigh is just a sigh / The fundamental things apply / As time goes by. / And when two lovers woo, / They still say, "I love you" / On that you can rely / No matter what the future brings-...
Rick: [rushing up] Sam, I thought I told you never to play-...
Rick: You know what I want to hear.
Sam: [lying] No, I don't.
Rick: You played it for her, you can play it for me!
Sam: [lying] Well, I don't think I can remember...
Rick: If she can stand it, I can! Play it!
Sam: Boss, ain't you going to bed?
Rick: Not right now.
Sam: Ain't you planning on going to bed in the near future?
Sam: You ever going to bed?
Sam: Well, I ain't sleepy either.
Captain Renault: I've often speculated why you don't return to America. Did you abscond with the church funds? Run off with a senator's wife? I like to think you killed a man. It's the Romantic in me.
Rick: It was a combination of all three.
Captain Renault: Realizing the importance of the case, my men are rounding up twice the usual number of suspects.
Captain Renault: Rick, there are many exit visas sold in this café, but we know that *you've* never sold one. That is the reason we permit you to remain open.
Rick: Oh? I thought it was because I let you win at roulette.
Captain Renault: That is another reason.
Rick: How can you close me up? On what grounds?
Captain Renault: I'm shocked, shocked to find that gambling is going on in here!
[a croupier hands Renault a pile of money]
Croupier: Your winnings, sir.
Captain Renault: [sotto voce] Oh, thank you very much.
Captain Renault: Everybody out at once!
Customer: Are you sure this place is honest?
Carl: Honest? As honest as the day is long!
Captain Renault: Ricky, I'm going to miss you. Apparently you're the only one in Casablanca with less scruples than I.
Captain Renault: What in heaven's name brought you to Casablanca?
Rick: My health. I came to Casablanca for the waters.
Captain Renault: The waters? What waters? We're in the desert.
Rick: I was misinformed.
Yvonne: Where were you last night?
Rick: That's so long ago, I don't remember.
Yvonne: Will I see you tonight?
Rick: I never make plans that far ahead.
Ugarte: You despise me, don't you?
Rick: If I gave you any thought I probably would.
Major Strasser: You give him credit for too much cleverness. My impression was that he's just another blundering American.
Captain Renault: We musn't underestimate "American blundering". I was with them when they "blundered" into Berlin in 1918.
Senor Ferrari: As the leader of all illegal activities in Casablanca, I am an influential and respected man.
