A man approached his family physician and said, "Doc, I'm afraid you'll have to remove my wife's tonsils (扁桃体）one of these days."

The doctor pulled out the family's medical file and exclaimed, "Why, 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?"
