Leonard: Buddy, I think Amy might be upset.
Sheldon: Why's that?
Leonard: Because your friend was rude to her, and then you went to dinner with him.
Sheldon: You're just repeating what I said. It's like living with a lactose-intolerant parrot.
Leonard: Trust me, call her.
Sheldon: Fine. It's a shame you didn't go to dinner with us, because the buffet you're about to enjoy only serves humble pie, a dessert much less tasty than frozen yogurt. I was this close.
