Wyatt: Leonard, you want to come in for a nightcap?
Penny: Oh, gee, dad, he'd love to, but Leonard has to work in the morning.
Leonard: Maybe I could go in a little late.
Penny: No, no, no, you can't. Your career is far too important.
Wyatt: Behind every great man is a nagging woman who won't let him have any fun, am I right, Leonard?
Leonard: Don't I know it.
