On subway platforms in NYC, there are these bright orange bars painted near the edge of the platform to warn you to stay back. My mom once told me that if i step on that bar, i'd get run over by the train. So natuarally i rationalized that there was a very small but very dangerous train which would run your foot over if you stepped on this bar.
