God breathes life into Adam and tells him... "You are man, my most favored creation, because of this I am going to give you the penis, and the brain." Adam replies..."Thank you lord, thank you so much, thank you. God says back to him, "Don't get to excited, there's a catch." Adam asks, "What is the catch?" God answers, "I'm only going to give you enough blood in your body to use one of that a time."
