Sheldon: Please, please, I don't have a lot of time. Ramona finally dozed off and I need you to help me get rid of her. Penny: Get rid of her how? Sheldon: I don't know, but apparently I'm in some kind of relationship, and you seem to be an expert at ending them. Penny: Excuse me? Sheldon: I see man after man leaving this apartment, never to return.
