My uncle was an engineer for a toilet paper manufacturing plant, that took logs in one end and put TP rolls out the other end. The path was over a mile long. He worked on variable speed electronic drives for the 1000 horsepower motors that turned the machinery. TP illustrates the triumph of civilization: 1000s of people all doing specialized jobs so billions of people can each avoid a daily unpleasantness.

Shizzles, I couldn't make a simple flame by myself ;p
