One day, in line at the company cafeteria,
Joe says to Mike behind him,
"My elbow hurts like hell. 
I  guess I'd better see a  doctor." 
 
"Listen, you don't  have to spend that kind 
of money" Mike replies 
"There's a diagnostic  computer down at Costco. 
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  costs ten dollars - 
A lot cheaper than a  doctor." 
 
So, Joe deposits a urine sample in a small jar 
and takes it to  Costco.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 @  Costco.." 
 
That evening, while thinking how amazing this new technology was, Joe 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 a sperm sample from himself for good measure. 
 
Joe  hurries back to Costco, 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 aren't yours.. 
    Get a lawyer. 
5. If you don't stop playing with yourself, 
   your elbow will  never get better! 
 
Thank you for shopping @ Costco!
