Penny: Are you saying that Amy is, uh, what’s the scientific word?
Sheldon: Forget science; she’s horny.
Penny: Oh, okay, wow.

Penny: Are you sure?
Sheldon: What are you suggesting?
Penny: I’m suggesting there might be something you could do about Amy’s urges.
Sheldon: It’s illegal to spay a human being.
