Big Bang Theory Quote
Leonard: Let me ask you something: if your friend thinks he's dating someone, but he's not, because in fact you're dating her, does that make you a bad person?
Penny: Well that depends.
Leonard: On what?
Penny: Is that friend Wolowitz?
Leonard: Yeah...
Penny: Screw him - you're fine.
Leonard: Are you sure?
Penny: Well... Have you slept with her yet?
(Leonard nods)
Penny: You dog! Good for you!
Leonard: Does that change things?
Penny: No.
Leonard: So, why did you ask?
Penny: I'm nosy!
