A man is at work one day when he notices that his co-worker is wearing an earring. This man knows his co-worker to be a somewhat conservative fellow, so naturally he's curious about the sudden change in fashion sense. The man walks up to his co-worker and says, "I didn't know you were into earrings."

"Don't make such a big deal, it's only an earring," he replies sheepishly.

"Well, I'm curious," begged the man, "how long have you been wearing an earring?"

"Er, ever since my wife found it in our bed."
