A man walks into a pharmacy to get a prescription
for his tennis elbow. When the pharmacist tells 
him it will take a few moments, the man wanders 
around the store a discovers an electronic 
medical booth. The booth says, add 50 cents, 
urinate in the cup, put in slot, wait five 
minutes for prognosis. Reluctant, the man does 
this, waits. A slip of paper comes out and says,
"you have tennis elbow." Shocked and skeptical 
the man runs home and tells his wife. He asks her
to piss in a cup, then asks his daughter to do 
the same, then masturbates into the cup. He then
stirs the mixture with his car's dip-stick. He 
runs back to the pharmacy, puts 50 cents into the
machine, adds the cup and waits. Five minutes 
later, the machine spits out, "Your wife has 
Herpes, Your daughter is pregnant, your car is a
quart low, and if you don't stop jacking off, 
your tennis elbow will never heal."
