I want to share with you an urban legend, some of you are probably familiar with it, what an injured brick layer wrote on his insurance form to explain how he had so many injuries after he tried to move 500 pounds of bricks from the top of a fourth story building to the ground below:
It would have taken too long to carry the bricks down by hand, so I decided to put them in a barrel and lower them by a pulley which I had fastened to the top of the building.
After tying the rope securely at the ground level, I then went up to the top of the building. I fastened the rope around the barrel, loaded it with the bricks and swung it out over the sidewalk and untied the rope, holding it securely to guide the barrel down slowly.
But since I weigh only one hundred and forty pounds, the five hundred pound load jerked me from the ground so fast that I didn’t have time to think of letting go of the rope. And as I passed between the second and third floors, I met the barrel coming down. This accounts for the bruises and lacerations on my upper body.
I held tightly to the rope until I reached the top, where my hand became jammed in the pulley. This accounts for my broken thumb.
At the same time however, the barrel hit the sidewalk with a bang and the bottom fell out. With the weight of the bricks gone, the barrel weighed only about forty pounds. Thus my 140 pound body began a swift descent, and I met the empty barrel coming up. This accounts for my broken ankle.
Slowed only slightly, I continued the descent and landed on the pile of bricks. This accounts for my sprained back and broken collar-bone.
At this point, I lost my presence of mind completely and let go of the rope and the empty barrel came crashing down on me. This accounts for my head injuries.
I hope this information satisfactorily fulfills your request for further information.
(NOTE: just for fun, at the end of this posted sermon is a video of a Mythbusters episode of a recreation of this story. Could it really happen? take a look...)
