You don't have to follow baseball to know that the Yankees-Red Sox rivalry is one of the most annoying in sports. So when a die-hard Boston fan meets his match with fourth grade Yankees fan (in the state of New York), it's gonna get ugly. Unfortunately for the young boy, he has no say when the teacher forces him to flip his shirt around and hide the Yankee colors. It must be a great feeling to be able to flex your authority over a 9-year old.
