For fans attending sporting events in Philadelphia, every game is a battle. Whether it's beer bottles, D batteries, snowballs, or vomit, one never knows exactly what could be flying one's way — especially if the Mets are in town. A homemade, chainmail-like jersey comprised of more than 3,000 beer and soda tabs may seem like overkill to the uninitiated, but it's really the minimal precaution every fan shoud take before venturing out among the frothing Philly masses. Just try to avoid getting tasered in this thing.
