One day, in line at the works cafeteria, Jack says to Mike behind him
"My elbow hurts like hell. I suppose I'd better see a doctor."
"Listen, don't waste your time down at the surgery," Mike replies.
"There's a diagnostic computer at WalMart. Just give it a urine sample and
the computer will tell you what's wrong, and what to do about it. It
takes ten seconds and only costs five quid.....a lot quicker And better
than a doctor".

So Jack collects a urine sample in a small jar and takes it to WalMart.
He deposits five 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"

That evening while thinking how amazing this new technology was, Jack
began wondering if the computer could be fooled. He mixed some tap
water, a stool sample from his dog, urine samples from his wife and
daughter, and masturbated into the mixture for good measure.

Jack hurried back to WalMart, eager to check what would happen. He
deposits five 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.
2. Your dog has ringworm. Bathe him with anti-fungal shampoo.
3. Your daughter has a cocaine habit. Get her into rehab.
4. Your wife is pregnant. Twins. They aren't yours. Get a lawyer
[try WalMart Law]
5. And if you don't stop playing with yourself, your elbow will
never get better...


Thank you for shopping at WalMart.
