"Alcohol?" said the man.  "I'm a teetotaler.  Never touch a drop."
        "How about smoking?" asked the doctor.
        "Never," replied the man.  "Tobacco is bad and I have strong
principles against it."
        "Well, uh," asked the doctor, "do you have much sex life?"
        "Oh, no," said the man.  "Sex is sin.  I'm in bed by 10:30 every
night....always have been."
        The doctor paused, looked at the man hard, and asked, "Well, do
you have pains in your head?"
        "Yes," said the man.  "I have terrible pains in my head."
        "O.K.," said the doctor.  "That's your trouble.  Your halo is on

too tight."
