I've recently become aware of a bizarre variation of rock-paper-scissors that includes dynamite. Players can use a thumbs-up gesture to represent the dynamite (thumbs is the fuse, the rest of the hand if the explosive.) While a rock-paper-scissors-dynamite game would never work (four moves is unbalanced), a rock-dynamite-scissors variant would make a lot of sense:
Rock crushes scissors
Dynamite blow up rock
Scissors cuts dynamite's fuse.
To me, this makes more sense than a system where paper beats rock. I mean, if you can stab the paper with the scissors, why can't you rip the paper with the rock? If you can cover the rock with the paper, why can't you gift-wrap the scissors?
The lesson: The pen may be mightier than the sword, but dynamite is mightier than pen and paper.
