Once upon a time there was an old man who found an old lamp out in the woods. It was dirty so he took it to the river to wash it. He rubbed it to get in clean. Old lamps tend to have a genie or similar inside them, which is awaken by rubbing. So was not in this case. This lamp was not old enough for that. The old man took the lamp in one hand and his stick in the other and walked back to his tent to study the fascinating object closer. He took his magnifying glass and with big wide eyes he looked at the peculiar items inside the light bulb. He searched for some form of keyhole or card slot without finding any. He tried with a magnet to see if anything interesting happened. Then he sat with the worthless item in his hand wondering what to do. Finally he sent it flying out in the woods again, totally unaware of that light bulbs hundreds of years earlier had been the major polluters of lead in nature.
