Lou Gehrig: Today, I consider myself the luckiest man on the face of the earth.

[repeated line]
Scarlett: Fiddledee dee

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: [aloud] Everybody out at once!

Rick: Last night we said a great many things. You said I was to do the thinking for both of us. Well, I've done a lot of it since then, and it all adds up to one thing: you're getting on that plane with Victor where you belong.
Ilsa: But, Richard, no, I... I...
Rick: Now, you've got to listen to me! You have any idea what you'd have to look forward to if you stayed here? Nine chances out of ten, we'd both wind up in a concentration camp. Isn't that true, Louie?
Captain Renault: I'm afraid Major Strasser would insist.
Ilsa: You're saying this only to make me go.
Rick: I'm saying it because it's true. Inside of us, we both know you belong with Victor. You're part of his work, the thing that keeps him going. If that plane leaves the ground and you're not with him, you'll regret it. Maybe not today. Maybe not tomorrow, but soon and for the rest of your life.
Ilsa: But what about us?
Rick: We'll always have Paris. We didn't have, we, we lost it until you came to Casablanca. We got it back last night.

Eliza Doolittle: I could have danced all night.

Professor Henry Higgins: By George, she's got it! By George she's got it! Now once again, where does it rain?
Eliza Doolittle: [sings] On the plain, on the plain.
Professor Henry Higgins: And where's that soggy plain?
Eliza Doolittle: [sings] In Spain, in Spain!
