NO EXIT!

A man checked into a hotel for the first time in his life, and goes up to his room.

Five minutes later he called the reception desk and said: "You've given me a room with no exit. How do I leave?"

The desk clerk said, "Sir, that's absurd. Have you looked for the door?"

The man said, "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't tried, but it has a 'do not disturb' sign on it."
