good joke about the new machine in tescos.,.,.,

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 mate ; don't waste your time down at the surgery, Mike replies.

There's a diagnostic computer at Tesco. 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 and you get Clubcard points'.

So Jack collects a urine sample in a small jar and takes it to Tesco. He
deposits five pounds 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 'pleasured himself' into the mixture for good
measure. Jack hurried back to Tesco, eager to check what would happen.

He deposits five pounds, pours in his concoction, and awaits the results
with a grin. 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.

5) And if you don't stop playing with yourself, your elbow will never
get better....

Thank you for shopping at Tesco
