Heated rivalries are at the heart of every competition. As the playoffs get under way, the Pittsburgh Penguins and Philadelphia Flyers provide one of the most intense matchups.
Game 1 on Wednesday night didn't disappoint. After spotting the Penguins a three-goal lead, the Flyers stormed back to win 4-3 in overtime. Those are the games that make political battles look bush.
Such a great opening game can make Democrats and Republicans go equally crazy enjoying playoff hockey.
