Mine is from my misspent youth when we got bored from rock-paper-scissors. Although it raises some interesting questions:
How do match and gun fare against lizard and Spock?
Obviously one of each set has to beat one of the other set.
I think gun has to shoot lizard but then Spock vaporizes gun.
Which means that lizard eats match but match burns Spock.
I am thinking that match burns rock....the rock is a lump of coal or something. Which means that rock smashes gun, and gun lights match.
Also it looks like Spock is the Live Long and Prosper sign.
How is lizard formed? Post 25 looks a little too close to rock.
Better story: Spock realizes the gun isn’t real (allusion to the episode Spectre of the Gun).
