Put it away sir

I was at the hospital recently (nothing serous, don't worry). The guy ahead of me in the queue for the reception desk gave his name, but the receptionist couldn't find his appointment, so asked him what he was doing there. 'I'm here to see the skin specialist' he said. He paused for a second then said 'Dermatosis' before thrusting his scabby hands in front of the receptionist's face. I'm just glad he didn't have VD.
