Alvy's mother: He's been depressed. All of a sudden,
he can't do anything.
Doctor: Why are you depressed, Alvy?
Alvy's mother: Tell Dr. Flicker. (To the doctor) It's something he read.
Doctor: Something he read, huh?
Alvy: The universe is expanding...Well, the universe is everything, and if it's expanding, some day it will break apart and that will be the end of everything.
Alvy's mother: What is that your business? (To the doctor) He stopped doing his homework.
Alvy: What's the point?
Alvy's mother: What has the universe got to do with it? You're here in Brooklyn. Brooklyn is not expanding.
Doctor: It won't be expanding for billions of years, yet Alvy. And we've got to try to enjoy ourselves while we're here, huh, huh? Ha, ha, ha. (He gives an artificial laugh before taking another drag on his cigarette)
