If doctors make so much money, why can't they afford new magazines for their waiting rooms? Judging from television commercials, there's a hemorrhoid epidemic in this country. A good many years ago, before the widespread use of ultrasound to determine an unborn child's sex, 3 pregnant women were sitting in their doctor's waiting room. "I'm going to have a boy," said one of the women. "How do you know that?" asked another. "Everyone knows that when the man is on top during conception, you'll have a boy." "Oh," said the first woman. "I guess that means I'll be having a girl, because I was on top during conception." The third woman burst into tears. "What's wrong, honey?" asked the first woman. Between sobs, the third woman said, "I'm going to have puppies."
