A stupid person checks into a hotel and goes up to his room. Five minutes later he halls the desk and say "You've given me a room with no exit. How do I leave?" The desk clerks says, "Sir, that's absurd. Have you looked for the door?" The stupid person says, " Well, there's one door that leads to the bathroom. There's a second door that goes into the closet. And there's a door I haven'yt tried, but it has a 'do not disturb' sign on it."
