Was at a urologist in a hospital and there were a couple of power cuts. Lights dipped out, generators kicked in. As he's finishing the examination, mid-sentence, the lights go out again. He gets up and walks out to check on things. Fifteen minutes later I'm still sat on the bed with my old chap out and pants around my ankles. A nurse walks past the open door and does one of those comedy double-takes. "....do you...do you have an appointment?" Turns out the doc had actually finished the examination, and returned to the ward some 15 minutes ago. To the nurse I was just some guy who had walked in and pulled his pants down and left the door open.
