Leonard: That's nice that they're getting along.
Raj: Your girlfriend and your ex-girlfriend are hanging out together? Oh, yeah, that can only be good for you.
Leonard: What are you talking about?
Raj: One of them broke up with you. Do you really want her telling the other one why?
Leonard: I don't care. I don't have anything to hide.
Raj: Good, good. Then you have nothing to worry about.
Leonard: No, I do not. You are a mean little man.
