A man is at work one day when he notices that his male coworker is wearing an earring. This man knows his coworker to be a normally conservative fellow and is curious about his sudden change in "fashion sense."

"Bob, I didn't know you were into earrings."

"Oh, yeah, sure," says Bob sheepishly.

"Really? How long have you been wearing one?"

"Ever since my wife found it in our bed."
