How we cite our quotes: All quotations are from Marty.
Quote #1
TOMMY: You tell Marty, Aunt Teresa, you tell him, "Go to the Stardust Ballroom. It's loaded with tomatoes."
The slang of the young in the mouths of the old is always worth a laugh. (Even if the slang is insanely outdated.)
Quote #2
MARTY: I also want you to know I'm having a very good time with you now and really enjoying myself. So you see, you're not such a dog as you think you are.
There's some connection here between a not-dog and social enjoyment: So when does "dog" refer to looks, and when is it just someone you don't want to spend any time with?
Quote #3
MARTY: Now I figure, two people get married, and they gonna live together forty, fifty years. So it's just gotta be more than whether they're good looking or not.
Seems legit. This is the kind of attitude that separates Marty from fairy tales. Marty is interested in the quality of that "ever after."
