An Englishman 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 gentleman replies, "If you weren't such a presumptuous bitch,You'd realize I was talking to the sheep."
