Rock, Paper, Scissors, Fire, Monkey . . .

A guy with way too much time on his hands has "enhanced" the reliable rock-paper-scissors game with 98 other options to throw and a complicated chart of how each option beats or gets beaten by all the others. Much more practical for anyone with enough time on their hands to actually play the game (say, a van full of students on the way to 86 Hours Summer Camp) -- the 25-throw version. You'll need the chart, lots of practice on the hand positions, and it wouldn't hurt to check out this Flash version of the game to figure out how it works.

Or, you know, you could just play rock-paper-scissors.
