#6 Rick (Humphrey Bogart) in "Casablanca". Something to the effect of:
Louis: Whay did you come here?
Rick: I came here for the waters.
Louis: But there are no waters in Casablanca.
Rick: I was misinformed.

And you've left out my favorite:

"So what's your point?"

Wait! Was that conversation with Louis or Major Strasser? Either way it was Rick who said it.
