Sheldon: Thanks for letting me stay here while Leonard Skypes with his girlfriend.
Penny: Oh, it's no problem. It's actually kind of nice. You reading, me reading. We're like an old married couple.
Sheldon: If we were an old married couple, the wife would serve iced tea and snickerdoodles.
Penny: I don't have iced tea and snickerdoodles.
Sheldon: A good wife would go to the store.
Penny: I want a divorce.
Sheldon: Good. On the way to see the lawyer, pick up some tea and cookies.
