If you've been to the rink to watch hockey, you've experienced it. You're there enjoying yourself while watching your favourite hockey team and then you see it. That one fan who is over the top. Sometimes it involves alcohol, often it involves the love of the team and the passion for the game.
Truth be told, there are dozens of fans who express themselves in this way, but they can be broken into two groups, the passionate and the annoying.
The camera shows, during a battle behind the Stars net, a Dallas fan dancing like a goof and hammering on the glass. Have a look:
What isn't known is who this individual is or whether they were paid entertainment to get the crowd into the game, but if that's the case, banging on the glass isn't necessary or appropriate. The actions of the individual could have had unintended consequences, as their was a possibility the glass could have popped out with their aggressive behaviour.
