Apparently, it's a thing for Nashville Predator fans to throw a catfish on the ice during a game. Pittsburgh doesn't think it's funny... at all.
The Preds fan, Jacob Waddell, that threw the fish onto the ice has been charged with disorderly conduct, possessing instruments of crime and disrupting meeting and processions.
The catfish was thrown on the ice during game 1 of the Stanly Cup Final.
Pittsburgh police say that Waddell brought the fish into the arena by vacuum sealing it and carrying it in compression shorts.
He went to the men's room during the game, removed the fish and threw it over the glass onto the ice.
The Pittsburgh Penguins defeated the Predators 5-3 in Game 1 to take a 1-0 lead in the best-of-seven series.
However, Carrie Underwood (her husband, Mike Fisher, plays for the Preds) went on twitter to approve of the move by the fish thrower.
Throwing a catfish on the ice has been a Preds tradition since 2003. Why a catfish? No one really knows. Maybe it has something to do with the Red Wings and their octopus tradition that started back in the 50's. Whatever the reason, the Preds fans love it. But the Pittsburgh people... not so much.
