Yes, it's been awhile since we've had some good parent-on-linesman hockey violence. No major injuries this time, but at least we have video!
This one comes from London, Ontario, and while I'm not sure what age the players are, I'm guessing they are mighty young. (I think it was Henry Kissinger who said that "hockey parents are so vicious, precisely because the players are so small.") The fight itself was largely uneventful—no charges were filed—and the parent did return later to apologize, but I think the real charm of the sport is shown in the women screaming obscenities off camera.
Such language! And from Canadians, no less! "Get control of the game, not my husband!"
