Earring

A man is at work one day when he notices that his co-worker is wearing an earring. The guy knows his co-worker to be a normally conservative fellow, and is curious about his sudden change in "fashion sense." He walks up to him 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. His friend falls silent for a few minutes, but then his curiosity prods him to ask, "So, how long have you been wearing one?" "Ever since my wife found it in my truck."
