Amy: So, Penny, how's married life?
Penny: Oh, it's good. I just wish Leonard would work up the courage to tell Sheldon he's moving in here.
Bernadette: You guys still aren't living together?
Penny: We are. I mean, he sleeps here. But it's only a matter of time before Sheldon has a bad dream and tries to climb into bed with the Leonard-shaped pile of pillows.
