I remember hearing a story about a Russian tzar who was drawing plans for a railroad. He was trying to draw a straight line by holding a ruler down with his thumb. The writing utensil he used hit his thumb and went around it, creating a bump. The railroad was built perfectly straight except that one bump in the middle of nowhere. Edit: apparently this was a myth, http://bigthink.com/strange-maps/580-the-legend-of-the-tsars-finger http://bigthink.com/strange-maps/580-the-legend-of-the-tsars... It is strange that all the crap I heard as a kid and took for granted for most of my life can suddenly pop into my head and now be verified because of the internet.
