Rock-paper-scissors is a zero-sum hand game usually played between two people in which each player simultaneously forms one of three shapes with an outstretched hand. The shapes are a rock (closed fist), paper (a flat hand) or scissors (a fist with two fingers extended to form a V like scissor blades). The game has three possible outcomes beside a tie. Rock beats scissors (rock crushes scissors) but paper beats rock (paper covers rock) and paper looses to scissors (scissors cut paper).
But a "Crumbs of Comfort" reader from Redlands, CA, USA, discovered another reason why paper beats rock, and that reason is sheer PERSISTENCE. Here's the photo he submitted as proof.
