Captain Renault: In 1935, you ran guns to Ethiopia. In 1936, you fought in Spain, on the Loyalist side.
Rick: I got well paid for it on both occasions.
Captain Renault: The winning side would have paid you much better...
Ugarte: Too bad about those two German couriers, wasn't it?
Rick: They got a lucky break. Yesterday they were just two German clerks. Today they're the "Honored Dead".
Ugarte: You are a very cynical person, Rick, if you'll forgive me for saying so.
Rick: [shortly] I forgive you.
Rick: Don't you sometimes wonder if it's worth all this? I mean what you're fighting for.
Victor Laszlo: You might as well question why we breathe. If we stop breathing, we'll die. If we stop fighting our enemies, the world will die.
Rick: Well, what of it? It'll be out of its misery.
Victor Laszlo: You know how you sound, Mr. Blaine? Like a man who's trying to convince himself of something he doesn't believe in his heart.
