A Scottsman 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."
