One day, in line at the company cafeteria, Joe says to Mike behind him, ‘My elbow hurts like heck. 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. 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: Thank you for shopping @ Costco!
