These two men were cellmates at state penitentiary for nine years. One day Larry said to Joe, "You know man its been a long time since we had some sex so you oughta let me screw you."
Joe replied. "Are you crazy?!!"
Larry went on to say, "I promise you that it won't hurt and we'll flip a coin and see who screws, who first.
So, Joe thought about it for a minute and finally agreed. They flipped a coin and Larry won.
Still having strong reservation Joe asked, "How will you tell if it hurts or not?"
Larry told Joe, "If it hurts you start making animal noises, and I'll stop.
But if it feels good start singing."
Larry started the insertion and Joe screamed, Moooooooo.... Moooooo... Mooooon River
