Laszlo: I'm sure you'll excuse me if I am not gracious, but you see, Major Strasser, I'm a Czechoslovakian.
Strasser: You were Czechoslovakian. Now you are a subject of the German Reich!
Laszlo: I've never accepted that privilege.
Strasser: Captain Renault, are you entirely certain which side you're on?
Renault: I have no conviction, if that's what you mean. I blow with the wind, and the prevailing wind happens to be from Vichy.
Renault: ... In 1935 you ran guns to Ethiopia. In 1936 you fought in Spain on the Loyalists' side.
Rick: And got well paid for it on both occasions.
Renault: The winning side would have paid you much better.
Laszlo: Isn't it strange that you always happened to be fighting for the underdog?
Rick: Yes. I found that a very expensive hobby, too. But then I never was much of a businessman.
