Y'know, this reminds me of an old joke.
It's about a guy who called his doctor complaining about a pain in his arm. The doctor tells him to come into the clinic, and bring a urine sample. So, the guy does, and trundles along. When he gets there, the doctor shows him this big shiny machine in his office and says "This thing arrived an hour ago and I've been itching to try it out. Here, just tip your urine sample into that funnel and press the green button."
The man does so. The machine clicks and whirrs for a second and then announces: "You have Tennis Elbow. take some painkillers and rest." The Doctor writes him a prescription for painkillers, tells him not to use his arm too much, and to come back in a week.
As his next appointment's coming round the next week, the man decides to test the machine's limits, and gets urine samples from his wife, daughter and father, mixing them with his own. For good measure, he ejaculates into the mixture, and then heads over to the office. As before, the doctor bids him empty the concoction into the machine's funnel and press the green button.
After whirring away for a few seconds and then announces:
"1: Your father needs a new hip, get him to a surgery.
2: Your wife is doing cocaine. Get her into rehab.
3: Your daughter is pregnant. Talk to her.
4: Your tennis elbow will not get better if you do not stop masturbating."
