A person checks into a hotel for

the first time in his life, and goes up to his room. Five minutes
later
he calls the desk and say, “You’ve given me a room with no
exit. How
do I leave?”
The desk clerk says, “Sir, that’s absurd.
Have you looked for the
door?”

The 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’t tried, but it
has a ‘do not disturb’ sign on it.”
