Scrap breaks out in the stands, bystanders step in and we get the craziest KO in hockey history

Shoutout to Reddit user Koquerelle for this next video.

Unfortunately though, I don't have much of a backstory. I don't know where and when this took place, I don't know what teams are involved. I literally know nothing... aside from this being the craziest KO in hockey history. That much I know.

Stick around until the end, I promise it's worth it.

Can't get knocked out by your opponent if you knock yourself out, am I right?
