Movies Chock Full of Great Lines

[matel]

I'll nominate Casablanca. Even though I find Rick and Ilsa not believable.

Senor Ferrari: As the leader of all illegal activities in Casablanca I am an influential and respected man...

Woman: What makes saloon keepers so snobby?
Banker: Perhaps if I told him I ran the second largest banking house in Amsterdam.
Carl: Second largest? That wouldn't impress Rick. The leading banker in Amsterdam is the new pastry chef in our kitchen.
Banker: .. We have something to look forward to..

Aninna: Monsier Rick, what kind of a man is Captain Renault?
Rick: Oh, he's just like any other man only more so.

Really thats just the tip of the iceberg with this movie.
Any others?
