How we cite our quotes: All quotations are from Annie Hall.
Quote #7
ALVY: It ruins it for me if you have grass because, you know, I'm like a comedian, so if I get a laugh from a person who's high, it doesn't count, you know, because they're always laughing.
In other words, Alvy thinks smoking pot cheapens the experience, or puts distance between him and Annie.
Quote #8
ALVY: It's all mental masturbation!
ANNIE: Oh, well now we're finally getting to a subject you know something about.
ALVY: Hey, don't knock masturbation! It's sex with someone I love.
Quips like these show that Alvy's perpetually performing. He doesn't just tell jokes on stage; he tells jokes constantly.
Quote #9
ALVY'S THERAPIST: How often do you sleep together?
ANNIE'S THERAPIST: Do you have sex often?
ALVY: Hardly ever. Maybe three times a week.
ANNIE: Constantly. I'd say three times a week.
This exchange shows that sex is subjective and open to interpretation, just like any other type of performance. Alvy thinks three times a week is "hardly ever." Annie thinks it's "constantly." (And we can all agree that Annie's therapist's office looks like the inside of a space station.)
