USA-Canada is quickly becoming the kind of grudge match you can respect and not one that makes you feel uncomfortable for Robert DeNiro. Prior to last night's throwdown in Grand Forks, these two teams also had a massive brawl in October in Burlington, Vermont. That's two fights in in three months and we're not even at the Olympics yet.

It all re-started Friday night when Canada's Brianne Jenner took a late run at Josephine Pucci, to which Team USA's Jocelyne Lamoureux objected. So, with nine seconds left in a 4-1 USA romp, she decided to ram Jenner into the boards.

Things quickly deteriorated. Lamoureux was joined by her twin sister Monique—if anyone at Team USA is paying attention, put these two (who scored a goal apiece, too) in Coke-bottle glasses ASAP—and the rest of their teammates, as the war on Canada raged on.

"I think we came in and defended our teammates, did what we had to do," Jocelyne Lamoureux, a former University of North Dakota star playing in her home rink, said after the Americans' 4-1 victory Friday night in the pre-Olympic exhibition game. "It's always going to be heated (against Canada). The intensity is always going to be there."

In all, 12 penalties were assessed in those final nine seconds.
