The best way to make a night memorable is to fuck something up deep within it very slightly, but also in a notable way. Also notably in a non-animal endangering way. That bars out something like putting live barracuda in the ice underneath the players, since that would go wrong in an exciting but might cost lives of players or fish. So the real way to make it memorable? People dressed as fish being harnessed and rappelled down from the ceiling during the pre-game. The caveat? Someone mysteriously forgets to pull them back up, and since the show must go on, the game is played with a bunch of human-sized fabric barracuda sadly dangling over the ice. This takes away the danger (ropes and harnesses are like, so safe) but would still go down as real memorable for fans. Plus the guys in the suits are gonna get paid a ton of money. Finally once the game has been finished, the fish men are lowered into the ice, and their harnesses are released from them so they can enter a coordinated dance routine on ice. The harnesses will also light on fire for the spectacle of it all. I don't think anyone would forget that.
