Janitor: I make more than you do.
J.D.: What?
Janitor: I saw your paycheck and I've been dying to tell you, I make more than you do. Quite a bit more.
J.D.: You couldn't have seen my paycheck.
Janitor: Right. Because there's no way I could access the personnel files. [holds up keys] Just impossible. By the way, 987654320.
J.D.: That's my Social Security number.
Janitor: No. That's your PIN number.
J.D.: No, my PIN number is 3674.
Janitor: Bingo.
