Juan complained to his friend, "My elbow really hurts. I guess I should see a doctor." His friend offered, Don't do that!" There's a computer at the drug store that can diagnose anything, quicker and cheaper than a doctor. Simply put in a sample of you urine and the computer will diagnose your problem and tell you what you can do about it and it only costs $10.00.

Juan figured he had nothing to lose, so he filled a jar with a urine sample and went to the drug store. Finding the computer, he poured in the sample and deposited the $10.00. The computer started making noises and the various lights started flashing. After a brief pause, out popped a small slip of paper on which was printed :

YOU HAVE TENNIS ELBOW
SOAK YOUR ARM IN WARM WATER
AVOID HEAVY LABOUR
IT WILL BE BETTER IN TWO WEEKS

Late that evening while thinking how amazing this new technology was and how it would change medical science forever, Juan began to wonder if this machine could be fooled. He decided to give it a try. He mixed together some tap water, a stool sample from his dog, and some urine samples from his wife and daughter. To top it off, he masturbated, poured in the sample and deposited $10.00. The machine again made the usual noise and printed out the following :

YOUR TAP WATER IS TOO HARD - GET A WATER SOFTENER
YOUR DOG HAS WORMS - GIVE HIM VITAMINS
YOUR DAUGHTER'S ON DRUGS - PUT HER IN REHAB
YOUR WIFE IS PREGNANT - IT AINT YOURS - GET A LAWYER
AND IF YOU DON'T STOP JERKING OFF YOUR ELBOW WILL NEVER GET BETTER
