Today In NHL History - Rob Ray Fights Fan

On April 14th in 1992, Rob Ray of the Buffalo Sabres pummeled a 21 year old fan who, apparently acting on a bet, elected to jump into the visitors bench at Le Colisée in the dying seconds of a game against the Quebec Nordiques.
Amazingly, the fan survived some 17 or 18 direct blows from the NHL's 6th all-time regular season penalty minutes leader (3,207) before police broke up the melee. Rayzor escaped criminal charges and league suspension that night though his team couldn't avoid a 7-3 loss.

That's today in NHL history.
