Since college I've enjoyed these kinds of verbal puzzles. The Teller sets forth a short story which is either incomprehensible or incomplete. Everyone else gets to pose questions to which the Teller can answer yes or no. They usually contain an 'aha' moment, when one person realizes the nub, the vital point of information, sometimes just a simple twist, most often grotesque, and then the original tale makes sense.
I've had a lot of fun with these tales, whether on the hiking trail or in a classroom of dangerously hyperactive high school kids who saw me as the 'sub'.

So I have a collection of them. Like a magician who must not give away the secrets of his trade, I have no intention of just 'giving' the plots away, but I'm curious to see how many other tales are out there.
The first one I ever learned is a perfect example:

1) A man goes into a bar and asks for a glass of water. The bartender pulls out a gun and points it at the man. The man says 'Thank You' and leaves.

A very simple one goes:
2) George and Martha are lying on the floor of a locked room, dead. The floor is wet and there is broken glass all around.

Another simple one:
3) A man is in a high rise apartment. He is ALL ALONE. He walks to the window, opens it, and jumps out. Just as he clears the sill, the phone rings. AND THEN HE SCREAMS.

This one took me a case of beer with friends and a hot afternoon in the trailers at Stanford:
4) A man is in a room, dead. There are two pieces of wood in the room.

5) A man walks into a restaurant and asks for baked albatross. They bring him baked albatross. He takes a bite, tastes it, then drops dead.

6) There is a dead man in a phonebooth. <-These days one might have describe what a phone booth is.

Yeah, there's lots of dead people in the ones I know.

so how about it, am I the only person who collects these? Are there others out there?
