A man is lying dead in the middle of a clearing, in the middle of a forest, in the middle of a puddle, in a scuba suit. How did he die?
Impact killed him. The man was swimming in a lake and there was a fire in the forest. A helicopter came to pick up water so the fire could be put out. It accidentally picked up the man and unknowingly dumped him from hundreds of feet on to the fire. He hit the ground and died.
What can be opened but can't be closed?
