Bernadette: What's wrong with his face?
Howard: A lot of people have been asking that. He's smiling.
Bernadette: Hey, Stuart, you look pretty happy.
Stuart: Oh, yeah. I, uh, asked Denise out on a date, and she said yes.
Bernadette: Aw. That's great. But don't smile like that in front of Halley. She just started sleeping through the night.
