The whole of the The Birdcage cracks me up.
Albert: Don't you use that tone to me.
Armand: What tone?
Albert: That sarcastic, contemptuous tone that means you know everything because you're a man and I know nothing because I'm a woman.
Armand: You're not a woman.
Albert: Oh, you bastard!
Nathan Lane and Robin Williams are amazing in that film.
