Sheldon: So, when could we start?
Penny: Okay, just to be clear. You are asking me for help because I know something that the brilliant Dr. Sheldon Cooper doesn't.
Sheldon: I suppose that's one way to look at it.
Penny: I think it's the only way to look at it.
Sheldon: Are you going to help me or not?
Penny: Probably. I'm just enjoying the foreplay. Does this mean you are done mocking my acting career?
Sheldon: Oh, I'm sorry, I thought making the transition from actor to acting teacher was the signal that one's career had reached the end of the road.
