### Three Doors

An airline captain was breaking in a new stewardess. The route they were flying had a layover in another city. Upon their arrival, the captain showed the stewardess the best place for airline personnel to eat, shop and stay overnight.
The next morning, as the pilot was preparing the crew for the day's route, he noticed the new stewardess was missing. He knew which room she was in at the hotel and called her up wondering what happened. She answered the phone, crying, and said she couldn't get out of her room. "
You can't get out of your room?" the captain asked, "Why not?"
The stewardess replied: "There are only three doors in here," she sobbed, "one is the bathroom, one is the closet, and one has a sign on it that says 'Do Not Disturb'!"
