A blonde checks into a hotel for the first time in her life, and goes up to his room. Five minutes later she calls down to the desk and says,
"You've given me a room with no exit. How do I leave?"

The desk clerk says, "Ma'am, that's absurd. Have you looked for the door?"

The person says, "Duh! 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."
