As two men are playing tennis, one man falls, hits his elbow and decides to go to a doctor. His friend says "Don't waste any money on a doctor. Just go inside the pharmacy down the street, put $10 into the machine in the corner wall, piss in the cup provided by the machine, put the cup back into the machine, let it do its thing and a slip of paper will come out that tells you what you have and how to fix it". Curious, the injured man goes down to the store, puts ten dollars into the machine in the corner wall, pisses into the dispensed cup, returns the cup to the machine and takes the piece of paper that comes out of the machine. As the man looks at the paper, he can see that it reads "You have Tennis Elbow. Buy the following ointment cream and apply it on your elbow 3-4 times a daily". The man buys the ointment cream from the pharmacist. When he goes home, he wonders how the machine knows what was wrong and wanted to see if the machine is a real miracle worker. So the next day, the man waits patiently and stealthily collects his sister's piss, brother's piss, dog's piss and then jerks-off all into one cup. He returns to the pharmacy, puts ten dollars in the machine, pours the contents of his cup into the dispensed cup and places the dispensed cup back into the machine. A paper then comes out from the machine which reads "Your sister has Gonorrhea, your brother is gay, your dog has Worms and if you keep masturbating like that you'll never cure that Tennis Elbow."
