"Oh my GOD!" said the lady, "That's disgraceful, why is he doing that?"
The doctor that was leading the tour explained; "I am sorry, but this man has a very serious condition in which the testicles rapidly fill with semen. If he doesn't do that five times a day, they'll explode and he will die within minutes."
"Oh, that's terrible," said the lady.
In the very next room they could see that a female nurse was giving a male patient a blow job. "OH my GOD!" said the lady, "How can that be justified?"
The doctor replied, "Same illness, better health plan."
