Amy: Are you sure that's the move you want to make?
Sheldon: Absolutely.
Amy: Okay. Checkmate.
Sheldon: Oh, I did not see that coming. That's well played, Amy.
Amy: What's going on?
Sheldon: You beat me, and I am responding with humility and admiration. What does it look like?
Amy: You let me win so you could show me how emotionally mature you are, didn't you?
Sheldon: Well, I couldn't wait for you to actually beat me; that would take forever.
