A man goes to the hospital and he passes a man in his room, masturbating furiously. He asks, "Doc, why is he doing that?" The doc says, "He was brought in with over-productive testicles, and if he doesn't relieve the pressure, his testicles will explode."
They walk a little further and they see a nurse performing oral sex on another patient. "What's his story?" he asks. Doc says, "Same condition, better health insurance." #jokes
