MR told me about this full-body improvement on Rochambault (or “Rock-Paper-Scissors,” as most of the world outside the SF Bay Area calls it): Bear-Cowboy Ninja. You start back to back with your opponent. Walk five paces, then whirl around and strike a pose.
The cowboy (hands making pistols and firing from both hips) shoots the bear.
The bear (hands up in the air in claw formation) eats the ninja.
The ninja (standing on one leg with hands out to the sides, like the Karate Kid) delivers a deathblow to the cowboy.
Sound effects are optional, but add greatly to the game.
On a related note, KJ and I played rock-scissors-paper one evening a couple weeks ago. After eight or nine consecutive ties, we had to give up. We know each other too well!
