Wil Wheaton: Did that guy just say "Revenge is a dish best served cold" to me in Klingon?

Bernadette: Maybe we should get one of those machines to help her up the stairs.

Leonard: Oh, I know. This might help. *Gets a ring out of his wallet*

Leonard: This would have been so much more romantic if you didn't have monkey hair on your finger.
