Riddle: A man is found dead in a room. The only thing in the room is a puddle of water. The man hangs by a noose on the ceiling. How did he die?
Answer: The man was standing on a big block of ice. While standing there, he tied himself to the ceiling. As the ice melted slowly, the man's feet started to sink to the floor while his neck was still tied to the ceiling. So when the ice finally melted, the man strangled himself and died. In the end, there was a dead body and a pool of water.
