Two Sets of Tonsils?
A young man approached his family physician and said, "Doc, I'm afraid you'll have to remove my wife's tonsils one of these days."
"My good man," replied the doctor, "I removed them six years ago. Did you ever hear of a woman having two sets of tonsils?"
"No," the husband retorted, "but you've heard of a man having two wives, haven't you?"
