A guy goes to see the doctor because of a sore elbow.
When he walks in, the receptionist gives in a bottle and ask him for a sample of urine.
“But I’m only here for a sore elbow” he protest.
The receptionist explains that the office has this new machine that can diagnose anything from a simple urine test.
So the guy complies and produce a urine sample which the nurse take into a back office.
When the guy is finally called into the doctor’s office, the doctor has a printed result and informs him that he is suffering from tennis elbow, so the doctor give him the appropriate treatment.
Some time later, he gets a called from the doctor’s office reminding him of his upcoming annual physical examination and to be sure to bring a urine sample because they now have that new technology that can diagnose anything from a simple test.
So our guy decide that he’s really gonna mess up their machine.
He collect a sample of his urine, jerks off and add some of the semen to it, in addition, he gets a urine sample from his wife, son and daughter and even adds a few drops of oil from his car engine.
On the day of the exam, he hands the sample over to the nurse, who again takes it to the back room.
After an unusually long wait he is called to see the doctor.
The doctor is studying the printout, finally he looks up and says,
“Well the verdict is, your car is overdue for an oil change, your wife is starting menopause, your son is gay, your daughter is pregnant, and if you don’t stop jerking off, your tennis elbow will not go away.”.
