Bill sees his friend John with an earring; somewhat perplexed Bill thinks to himself, “Strange I’ve never seen John with an earring before?”

Curiosity got the better of Bill and he decides to walk over and ask John the reason for the earring:

 “None of my business John I know,” said Bill, “but I’ve never noticed you with an earring before?”

“No big deal” retorted John, “every one’s wearing them these days.”

“That’s true,” Bill responded, “but you were always the conservative type. When did you start wearing the earring?”

“Since the wife found it in the back seat of the car two days ago,” replied John.
