Big Bang Theory Quote
Sheldon: Amy's sick.
Leonard: Aw, what's wrong with her?
Sheldon: Well, she talks a lot. She always wants to hold hands.
Leonard: That's not what I meant.
Sheldon: If you were refering to her illness, you should have asked "What ails her?"
Leonard: What ails her?
Sheldon: Oh, who knows.
