Alvy's Mother (to the Doctor): He's been depressed. All of a sudden, he can't do anything.

Doctor: Why are you depressed, Alvy?

Mother: Tell doctor Flicker. It's something he read.

Doctor: Something you read, eh?

Alvy (sullen): The universe is expanding.

Doctor: The universe is expanding?

Alvy: Well, the universe is everything, and if it's expanding, someday it will break apart and that would be the end of everything!

Mother (shouting): What is that your business? He stopped doing his homework!

Alvy: What's the point?

Mother: What has the universe got to do with it? You're here in Brooklyn! Brooklyn is not expanding!

from Annie Hall (1977)
