A new intern is getting a tour of the hospital he is working in. The intern walks past a room where a man is vigorously masturbating nonstop.

The intern asks the doctor he is with why that man was doing such a thing out in the open. The doctor answers, Oh, he has a medical condition where the sperm builds up so quickly in his body he has to masturbate constantly or he will explode. Oh, I see, says the intern.

They walk past another room where the intern sees a man laying on a stretcher getting a blow job from a nurse. Again, he asks the doctor, What is up with THAT? The doctor says, Same condition, better medical plan.
