Wednesday night, the Penguins and Capitals renewed acquaintances as they met for the first time this season in Washington.
What started as a rivalry between Sidney Crosby and Alexander Ovechkin has turned into a fierce rivalry between the two teams, and the bad blood has become even worse recently as the Penguins have knocked out the Capitals in the second round of the playoffs in each of the past two seasons.
The first meeting of the season between the Pens and Caps was a good one, but Washington fans weren't happy with the result as Pittsburgh won 3-2.
After the game, Penguins fans continued the tradition of celebrating the victory on the steps of the National Portrait Gallery.
What makes this tradition so awesome is that the steps are adjacent to the arena, so Caps fans can't avoid seeing Pens fans celebrate beating their team if they leave that way.
Plus, the chants are pretty savage, too, and that's another reason why we love this tradition and rivalry.
The Capitals will try and get some revenge on November 10th when the Penguins come back to town.
