Pinnochio tells his Dad that whenever he has sex with a girl, she complains about the splinters. His father gives him a piece of sand paper and tells him to rub his dick with it before sex and it should solve the problem.
A few days later, his father asks: "How are things going with the girls?" Pinocchio tells him: "Girls... who needs girls?"
Preparing the body of old man Johnson, a mortician finds the largest penis he has ever seen. "I'm sorry" he says out loud, "But I can't send you off to be cremated and lose forever such a rare and enormous dick like yours. It has to be preserved for posterity."
So the mortician carefully removes the giant organ, places it in a jar and puts the jar in his briefcase. When he gets home, he's excited to show the rare sight to his wife. "Look here honey, I have something to show you that will shock you." he tells her as he removes the jar from his briefcase.
