Speaking Of Tennis Elbow

I thought about posting this in the tennis elbow thread, but things are getting a little contentious over there and I didn't want to ruffle any feathers:

A man complained to his friend "My elbow hurts I better go to the doctor." "Don't do that," volunteered his friend "there's a new computer at the drug store that can diagnose any problem quicker and cheaper than a doctor. All you have to do is put in a urine sample, deposit $10, then the computer will give you your diagnosis and plan of treatment."

The man figured he had nothing to lose so he took a sample of urine down to the drug store. Finding the machine, he poured in the urine and deposited the $10. The machine began to buzz and various lights flashed on and off. After a short pause, a slip of paper popped out on which was printed:

You have tennis elbow. Soak your arm in warm water twice a day. Avoid heavy labor. Your elbow will be better in two weeks

That evening as the man contemplated this breakthrough in medical science, he began to suspect fraud. To test his theory he mixed together some of his own urine with some from his dog, from his son, and from his wife.

He took this concoction down to the drug store, poured it in the machine, and deposited $10. The machine went through the same buzzing and flashing routine as before then printed out the following message:

"Your wife is preganant, your dog is in heat, your son is going through puberty, and if you don't stop masturbating so much, you are going to get tennis elbow."
