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."
