Guy went to doctor because of a sore shoulder. Doctor gave him a bottle and said bring in a urine specimen. Guy thought doc is crazy as hell, sore shoulder--urine specimen??? So he thought I'll fix him. Took bottle and asked his wife to provide a small sample, then had his daughter provide one. He then went out to his car and put some oil off the dipstick in. Then he masturbated and put some of that in. Shook bottle real well and took it to the doctor. Doctor came in with results and told the patient to set down he has some serious problems. Doc said first off, your wife is having an affair, your daughter is pregnant and your car is about to throw a rod. And if you don't quit beating off your shoulder never will get well.
