A new intern is getting a tour of the hospital he will be working in. He walks past a room where a man is vigorously masturbating non-stop, and asks the doctor why the man was doing such a thing out in the open?

The doctor replies, "Oh he has a medical condition where the sperm builds up 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's up with that?"

The doctor says, "Same condition, better medical plan."
