Rob is at work one day when he notices his co-worker is wearing an earring. Rob knows his co-worker to be a normally conservative fellow and is curious about his sudden change in "fashion sense." So 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," the friend replies sheepishly. Rob 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 car." I always wondered how this trend got started.
