Those who believe that masturbation is unnatural and ungodly should note the above diagram. This shows clearly and irrefuteably that God meant for us to masturbate. Years of painstaking research have gone into this finding. The proof lies in the length of the human arm. Whether through evolution or by direct design, God has ensured that the human arm is exactly the perfect length to reach the genitals (or "Rude Bits" as they are known in scientific circles). If God had not wanted us to masturbate, he'd have given us short arms like a Tyrannosaurus Rex.
