Here's and interesting essay describing the world of Competitive Rock Paper Scissors.

The Rock Paper Scissors enthusiast is Jason Simmons, and on the count of four, he makes his fist into the sign for rock. The man in the cowboy hat throws scissors, and Simmons wins. You may believe that Simmons got lucky and that he had an equal chance of winning, tying, or losing. Simmons - who goes by the nickname Master Roshambollah and the honorific the greatest player in Rock Paper Scissors history - does not. That is why he is in a shopping mall with a camera crew, challenging strangers to play a game usually used to decide who rides shotgun, in order to promote the USA Rock Paper Scissors League.
