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: 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.
