Leonard: All right, well, after we talked about my issues with my mother - nothing too deep, just how she ruined my life - I told her about you and your drug; she said she'd be happy to meet you.
Penny: Really? Oh, you're the best husband ever!
Leonard: So you'll go to the Doctor Who convention with me next week?
Penny: I guess.
Leonard: Oh, I actually did hear your eyes roll that time.
