Really funny jokes-Do not disturb

A hillbilly named Billy Bob checks into a hotel for the first time in his life, and goes up to his room. After a few minutes, he calls the desk and say, "My room does not have any exit. How do I get out?"

The reception clerk replied, "Sir, that's ridiculous. Have you looked for the door?"

Billy Bob says, "Well, there is one door to the bathroom. There's a second door to the closet. And there's another door which I have not tried, but it has a 'do not disturb' sign on it."
