An angry lady stormed into an opthamologist’s clinic. She complained to the doc, “Someone stole my wig while I was having surgery yesterday.”

The doc tries to soothe her, “I assure you, ma’am, that no one on my staff would do that. 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, ma’am, that means your cataract operation was a success.”
