Steelers Fan Begins Celebrating Team's Playoff Berth Early, Gets Embarrassed

Everyone knows the old adage "you play until the whistle blows," but "you don't start celebrating until the game is over" should also be added to that. 

This Pittsburgh Steelers fan learned the hard way as he began dancing as the Kansas City Chiefs lined up for a potential game-winning field goal that would've sent Pittsburgh into the playoffs. Following the missed field goal, the Chargers won in overtime, knocking the Steelers out of contention. 

Better luck next year, buddy.
