I attended a family dinner at BJ's. The televisions in the annex were tuned to a Sharks vs. Stars hockey game.
At one point during our meal, my uncle exclaims: "WHOA! They're fighting!"
I look up and see this:
"Why is no one stopping them?" I wonder out loud. "In any other sport…"
My cousin: "In the NHL, fights continue until one combatant's knee touches the ice."
"WHAT? That can't be right… What if both combatants have extremely good balance? Or what if one combatant's strength is his ground game?"
According to WikiAnswers, the longest fight in NHL history lasted 20 minutes. That's four times as long as the alley fight in They Live.
