A nurse is at the hostpital for her first day of training, and a doctor is showing her around. They pass a room and inside she notices that there's another nurse in there giving a patient a handjob, so she says to the doctor "What's going on in there". to which the doctor replies "That man has a rare desease. If he doesn't cum twice a day, he'll die". The nurse, a little concerned, accepts this answer. A little while later, they pass another room where insided is a nurse giving a patient a blowjob. The nurse says "Doctor, what's going on in there"! to which the doctor replies "Same desease, better medical plan"!
