A variation of paper rock scissors where the players act the part rather than using their hands. Two players stand back to back and take three paces away from each other as in a gun duel. They then quickly turn to face each other and act the part of a bear, ninja, or cowboy. The bear mauls the ninja to death, the ninja kicks the cowboy's ass, and the cowboy shoots the bear.
Okay man, bear beats ninja, ninja beats cowboy, and cowboy beats bear.
