A man goes to his physician and is shocked to find that he has been replaced by a super-computer. The computer asks him his ailments and the man says he has a sore elbow. A drawer pops out and he is asked to urinate in it. After a few bleeps and flashing lights the computer decides he has tennis elbow.
The man is annoyed and decides to get one over on this machine so he asks his wife for a urine sample. He then mixes this with urine from his dog and his small son and to top it off, adds some of his sperm. He takes it to the computer-physician who again asks him for a sample. He places the urine/sperm sample in the drawer and the computer makes its usual display of bleeps and flashes before telling him that his wife is pregnant, his dog has rabies, his son has chicken pox and if he doesn't stop masturbating he'll never get rid of his tennis elbow.
