Penny: Well, I'm going to take myself out to a movie tonight. You want to go?
Leonard: Really? Do we do that?
Penny: What do you mean?
Leonard: You know, we haven't spent time alone together since we broke up.
Penny: Oh, it's not a date, Leonard. It's just a man and a woman hanging out, and not having sex at the end of the night.
Leonard: Sounds like most of my dates.
