Howard: Well, gotta go.
Bernadette: Oh! Already? Why don't you stay over?
Howard: Well, I'd love to, but you know my mother needs me in the morning.
Bernadette: Please, I think the woman can manage to put a wig on by herself.
Howard: It's not just the wig. It's pinning her hair up, drawing on her eyebrows. It's a two-person job.
