A man visited his doctor and complained of feeling bad. Because there were
no apparent medical problems, the doctor gave the patient a thorough exam;
he found nothing wrong. After thinking on the situation for a few minutes,
the doctor asked the patient about his diet. "Tell me what you typically
eat for breakfast," the doctor said. "Oh, a pound of bacon, a dozen eggs,
a loaf of toasted bread, two or three pots of coffee. And maybe six or
seven dounuts if I'm really hungry." "That's a pretty big breakfast," the
doctor said. "What do you eat for lunch?" "Nine or ten hamburgers, four or
five milkshakes, and a pie or two." The doctor was amazed. "And what do
you have for dinner?" "That's my big meal," said the patient. "I usually
have three or four helpings of salad, four or five steaks, five or six
baked potatoes, eight or nine dinner rolls and five or six pots of coffee."
The doctor shook his head and said, "Drop your pants again; then turn
around and bend over." The man did so and after the doctor looked closely
he told the guy, "There's your problem! You have only one asshole ..."
