The penis is the male reproduction organ and the reason I believe there is a God. The penis is a remarkable peice of workmanship. Completely thought out - for example, look at the head..it is shaped for easy entry, soft to cushion the blow - it even has a "seam" on the underside to avoid suction. Perfect.
