Thump drag, Thump drag.

One fire in the cabin going out, one kid sent out for wood, and one psychopath in the woods with a wooden leg that makes the noise of thump drag, thump drag. The kids in the cabin sent out a kid to get the wood knowing there was a psychopath somewhere in the woods, so they made a secret knock. The kid went out in the forest with an ax to get the wood. The kids here a thump drag, thump drag. They start panicking, so they go to the door and start piling stuff up to hold him out. All of a sudden they hear a bang bang bang bang bang on the door, and tell themselves not to open the door, since he's not using the secret knock. In the morning they tell themselves to open the door together, but when they open the door they see their friend lying on the ground with his legs off.
