Other mistake: In the championship game, the Yankees batter hits a foul ball when they score their winning runs.
Deliberate mistake: In the championship game, when number three on the other team hits a home run, he never touches home plate. Home plate is where all of the players are crowded around (primarily the ones to the left of the scene). The player makes a "jump stop" at the batter's box. The Bears could have waited 'til the player went back to the dugout; the catcher, with the new ball in play, would have stepped on home plate, and the home run never would have counted.
