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 normally, conservative fellow, and is curious about his sudden change in "fashion sense."

The man walks up to him and says, "I didn't know you were into earrings."

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

His friend falls silent for a few minutes, but then his curiosity prods him to say, "So, how long have you been wearing one?"

"Ever since my wife found it in my truck."
