BETTER THAN EATING THE EVIDENCE

Morris is at work one day when he notices that his co-worker, Joe, 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."

"Hey Joe, he yells out - I didn't know you were into earrings."

"Don't make such a big deal out of it,...it's only an earring." Says Joe sheepishly.

"No really," probes Morris, "How long have you been wearing one?"

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