The gynecologist is surprised to see one of his patient’s husbands in his waiting room. “What can I do for you Mr. Doyle?” the doctor asks. “I’m worried because our new baby has red hair.” “Why is that such a concern?” “I have black hair, my wife has black hair and all four of our parents have black hair.” “How often do you have sex?” “Oh, I guess about twice a year,” Doyle says, sheepishly. “That explains it,” says the doctor. “The red hair is from rust.”
