How did he accidentally
have sex with himself? He didn't recognize himself? He's an idiot?
Of course I have thought of the masturbating objection to this plan. But if you meet a clone of yourself they have had different life experiences than you. The way it goes in my mind is the clone says, "oh let me do THIS" and I'm like, wtf for? And the clone says, "you'll see.." Or vice versa. It's like your body went off and lived a different life from you and has something to tell you about yourself that never entered your head.
