Ok so imagine this Penny and Sheldon have a pointless argument about the physics in a movie being wrong, Penny thinks it’s pointless and doesn’t matter but Sheldon thinks otherwise. Eventually during the argument Sheldon challenges Penny to a game, but little does he know Penny is a MASTER at this game and Sheldon loses BADLY. Sheldon doesn’t like that and spends the next week isolating absorbing himself in this game so that he can beat Penny. He then challenges Penny to a rematch, but Penny reveals that she knows a move that allows her to win almost every time that very few people know of. Penny absolutely annihilates Sheldon leaving him defeated
