One day, in line at the company cafeteria, Joe says to Mike behind him, "My elbow hurts like hell. I guess Id better see a doctor."
"Listen, you dont have to spend that kind of money," Mike replies
"Theres a diagnostic computer down at WalMart. Just give it a urine sample and the computer will tell you whats wrong and what to do about it.
It takes ten seconds and costs ten dollars - A lot cheaper than a doctor."
So, Joe deposits a urine sample in a small jar and takes it to WalMart.
He deposits ten dollars and the computer lights up and asks for the urine sample. He pours the sample into the slot and waits.
Ten seconds later, the computer ejects a printout:
"You have tennis elbow. Soak your arm in warm water and avoid heavy activity. It will improve in two weeks. Thank you for shopping @ Wal-Mart."
That evening, while thinking how amazing this new technology is, Joe begins wondering if the computer could be fooled.
He mixes some tap water, a stool sample from his dog, urine samples from his wife and daughter, and a sperm sample from himself for good measure.
Joe hurries back to Wal-Mart, eager to check the results. He deposits ten dollars, pours in his concoction, and awaits the results.
The computer prints the following:
1. Your tap water is too hard. Get a water softener. (Aisle 9) 2. Your dog has ringworm. Bathe him with anti-fungal shampoo. (Aisle 7) 3. Your daughter has a cocaine habit. Get her into rehab. 4. Your wife is pregnant. Twins. They arent yours. Get a lawyer. 5. If you dont stop playing with yourself, your elbow will never get better!
