One thing that I do know about hockey players is that they love to drop the gloves but in the below video; two KHL hockey teams dropped the gloves within seconds of the game beginning.
It happened in a game between Avangard and Vityaz in Russia when six seconds in, both teams started brawling.
To note, these teams had a history and had another brawl back in January:
