Yeah, I don't think screaming "but you're supposed to be neutral!!!" while you were getting your ass beat would've helped too much in that situation.
All you ever needed to know about hockey... it's legalized bloodsport on ice.
"I went to a fight and a hockey game broke out"...
When presented with a conversation about hockey and you know nothing about the game, you have two options. Both will end your participation in the hockey topic:
1. "Which team lost the most blood?" (Person will rave gleefully for at least half an hour on all of the fights in the game, requiring no further input other than approving grunts from you.)
2. "Sorry man, the only hockey I want to talk about right now is a 'body check' on that hot blonde/brunette/redhead over there." (Person will turn to look and the topic will then turn to comparing hot babes in the near vicinity or past conquests.)
