Sheldon: Raj, you were being a good friend, and my illness was no excuse for my behavior. I hope that you can accept my apology.
Raj: Of course I do.
Sheldon: And, Emily, I'm sorry for saying dermatologists aren't real doctors. And I'm sure you're tired of hearing that.
Emily: Do you honestly think I hear that a lot?
Sheldon: Well, I would imagine when your job is popping zits and squirting Botox into old lady faces-
Raj: Okay! Okay, the point is that we accept your apology.
Emily: Uh, maybe you do. He just insulted me again.
Raj: Yeah, but he doesn't mean it.
Emily: Why are you defending him?
Sheldon: I believe I can answer that. Uh, like me, Raj is demonstrating empathy.
Now, why don't you accept my apology, receive your free T-shirt, uh-- I hope extra small is okay. For some reason Wolowitz took a medium.
