A man walks into the bedroom with a sheep on a leash and says, "Honey, this is the cow I make love to when you have a headache." The wife, lying in the bed reading a book, looks up and says, "If you weren't such an idiot, you'd know that's a sheep, Not a cow." The guy replies, "If you weren't such a presumptuous bitch, You'd realize I was talking to the sheep."
