I know this one :)

Ok, here is another one: One woman in a black clothes with a maid went to a hotel. They have two rooms close to each other. After some time there was a loud groan (cry) from the maid's room. The woman was found dead and all her clothes disappear... What happened?

This kind of stories are called "situations" and the person, who tries to find out, what's the sense of it, should ask questions, on which the teller can answer only Yes/No/Doesn't matter.

Here is another simpler one: One person was found dead in the dessert with the cause of his death on his back... What happened?
