Penny: God, what is wrong with me.
Leonard: Nothing, you're perfect.
Penny: Gah, I'm not perfect.
Leonard: Yes you are.
Penny: You really think so, don't you? [kisses Leonard]
Leonard: How much have you had to drink tonight?
Penny: Just…. a lot.
Leonard: Are you sure that your being drunk, and your being angry with Kurt doesn't have something to do with what's going on here?
Penny: It might. Boy, you're really smart.
Leonard: Yeah, I'm a frickin' genius.
