Two men are playing tennis when one of the men falls and hits his elbow on the court. He tells his partner that he has to stop playing to visit his doctor.

"Don't waste any money on a doctor," the other man says, "just go inside the store at the corner, put $10 in the machine in the back, piss in the cup and let it do its thing. A slip of paper will come out telling you what you have."

So he goes to the store, puts $10 in the machine, pisses in the cup and a piece of paper comes out proclaiming: "You have tennis elbow. take this ointment cream and apply it on your elbow three to four times daily."

The man is so amazed that he goes home and collects his sister's urine, his brother's urine and his dog's urine and puts it into a single cup. Then, just for good measure, he includes a personal semen sample in the cup as well.

Once he's done, the man goes back to the store, inserts $10 and places the cup in the machine. After a moment, the paper comes out and says: "Your sister has gonorrhea, your brother is gay, your dog has worms, and if you keep jacking off like that you'll never lose that tennis elbow."
