Here are the rules: Scissors cuts Paper covers Rock crushes Lizard poisons Spock smashes Scissors decapitates Lizard eats Paper disproves Spock vaporizes Rock crushes Scissors. My favorite part is "Paper disproves Spock." Haha! Anyway, this got me thinking of other TV shows I've watched where other variations of rock-paper-scissors were used. In That 70s Show, Hyde and Fes were playing a nuclear war version, Foot-Cockroach-Nuclear Bomb. Hyde described the rules as "Foot squashes cockroach, nuclear bomb blows up foot, and cockroach survives nuclear bomb!" I remember an episode of Friends where Ross, Rachel, Joey and Pheobe were playing rock-paper-scissors except Joey used fire and said fire beats everything. Then Phoebe whipped out the water balloon and put out the fire. Very cute.
As for the lizard-spock expansion, I found out that it was made up by some guy named Sam Kass a few years back. He and his wife made it up while they were dating and are confessed geeks. And guess what else! He went to my alma mater. That explains a lot. Isn't it weird how you find some connection with a total stranger?
Anyway, go forth and play rock-paper-scissors-lizard-spock.
