When Mary comes into the office dressed like a man, Murray says, 'I bought a suit like that for my son'. Murray doesn't have a son until Season 5 Episode 12 when he adopts a son because he desperately wants a son.
Lou: (about Mary's interview) It'll be fun. You get your name in the paper. Your folks will read it. They'll be proud. Sure, have a nice time.
Mary: Okay, thanks.
Lou: Just don't say anything.
Ted: Say, Murray, just between us guys, if Mary were a man, would she be better looking than I am?
Murray: Ted, if Mary were a duck, she'd be better looking than you are.
Rhoda: (about Mary refusing Mark's advances) It's good what you did. I think he was testing you, to find out what kind of a girl you are. Now he knows, and he'll respect you for it. And he'll call you as soon as he can.
Mary: Do you really think so?
Rhoda: No, but my mother does.
Ted: (to reporter in crowded restaurant) I sleep in the raw.
