magic lights

An 80 year old man named "Harry" went to the Dr. for his yearly check up and after all the tests were done the Dr. sat him down and said " Harry,hows everything from your perspective?" Are you right with God? Harry responds with " Life is great I even have such a discourse with the man above that when I get up in the middle of the night to go to the bathroom to relieve myself that when I begin "POOF" the lights go on and when I leave "Poof" the lights go out.After some more genial conversation Harry leaves for home.After Harry leaves,the Dr. being quite puzzled calls Harry's wife "Ethel" to question her about the bathroom lights.And when she responds understands,Oh My God Harry's peeing in the refrigerator again!
