A very angry woman stormed up to the receptionist's desk. "Someone stole my wig while I was having surgery yesterday," she complained.
The doctor came out and tried to calm her down. "I assure you that no one on my staff would have done such a thing," he said. "Why do you think it was taken here?"
"After the operation, I noticed the wig I was wearing was cheap-looking and ugly."
"I think," explained the surgeon gently, "that means your cataract operation was a success."
