A guy tried to do that to me once when I was tending net about a couple years ago. (To be fair, he did it because I had pushed his feet out from under him.) He did it for about 10 seconds and then a puck hit him square in the back. It was hilarious.
But seriously, that should be unsportsmanlike conduct.
You know, it's kind of embarrassing to be the fan of a last place team; everyone disrespects you, implies that your team's management is incompetent, and gloats about how their team is so much better. I guess it could be worse, though; my team could be hyped as a playoff contender and then get buttfucked on national television. Ahh, delicious, delicious Schaudenfrude.
