Mary: Why are you smiling at me?
Lou: Because you just reaffirmed my faith in human nature.
Mary: You mean what I did wasn't rotten?
Lou: Oh, no, that was rotten all right. It's just nice to know that everyone's rotten. Up to now, I thought you were one of the few holdouts.
Phyllis: (to Mary and Rhoda) I thought I'd see how you swingin' singles spend your evenings!
Rhoda: They're not much different than yours. We sit around at night wondering what it'd be like to have a happy marriage.
