There was a man who went to see the doctor for the first time in years, and complained that he wasn't feeling well. At last, he was admitted in to the doctor, and the conversation went something like this:
"Let's begin with a few questions," says the doctor. "Do you drink much?"
"Alcohol?" says the man. "I'm a teetotaler. Never touch a drop."
"How about smoking?" asks the doctor.
"Never," replies the man. "Tobacco is bad, and I have strong principles against it."
"Well," asks the doctor, "do you have much sex life?"
"Oh, no," says the man. "Sex is sin. I'm in bed by 10:30 every night, and I always have been."
The doctor pauses, looks at the man hard and asks, "Well, do you have pains in your head?"
"Yes," the man says. "I have terrible pains in my head."
"OK," says the doctor. "That's your trouble. Your halo is on too tight."
