The Toronto Maple Leafs turned to a bit of celebrity power to try to help them get going on Tuesday night. Down 1-0 in the second period in Game 5 of their first-round playoff matchup against the Ottawa Senators, Toronto-born actor and massive Leafs fan Will Arnett was brought out during a commercial break to lead the sold-out Scotiabank Arena crowd in a cheer. His appearance might've hyped up the crowd, but it didn't exactly have an immediate effect on the ice, as the Leafs entered the final frame of the game still being held scoreless. For Arnett, he'll be hopeful that he won't have to be in Toronto again for this series, with Toronto's next possible home game being a winner-take-all Game 7. Why is Arnett a Leafs fan?
