Jones took his nymphomaniac wife to the doctor for treatment. "This is one hot potato of a lady, doctor, " he said. "Maybe you can do something for her? She goes for any man and I get very jealous."
"We'll see," the doctor said. He directed Mrs. Jones into his examining room, closed the door behind him and told her to undress. Then he told her to get up onto the examining table on her stomach. The moment he touched her buttocks, she began to moan and squirm. It was too much for him to resist, and he climbed up on top of her and began to screw her. Jones suddenly heard moans and groans coming from the room.
Unable to control himself, he pushed open the door, to be confronted by the sight of the doctor astride his wife banging away. "Doctor, what are you doing?" he asked. The flustered doctor said, "Oh, it's you, Jones? I'm only taking your wife's temperature! "
Jones opened his switchblade knife and began to hone it on his sleeve very deliberately. "Ok Doc," h said, "but when you take that thing out, it better have numbers on it!"
