rock paper scissors spock lizard (idea)

This is a game just like rock, paper, scissors except more complicated and less predictable. An excerpt from
http://www.vtiscan.com/~samkass/theories/RPSSL.html
where I read of this amazing addition to the roshambo field of study:

Scissors cuts Paper covers Rock crushes Lizard poisons Spock smashes Scissors decapitates Lizard eats Paper disproves Spock vaporizes Rock crushes Scissors

Yes, folks, that whole 'Scissors decapitates Lizard' thing bothers me, too.
