This weekend's competition in Wisconsin is a bit more intense than it was in your grade school gym class.
The Chicago Blackhawks face-off against the Boston Bruins on Monday night, in what could be the Stanley Cup clincher.
The Blackhawks lead the series 3-2 and need only one more win to defeat the Bruins in the seven-game series.
But no one is writing off the B’s, who stunned fans with one of the most dramatic comebacks in a single game in their quarter-final series against Toronto.
At least one sports watcher has called this series the best played and most skilled in hockey history.
