Fallon cuts loose on JumboTron at Rangers-Flyers game at MSG

Jimmy Fallon can't help but dance when the camera finds him at Madison Square Garden.

The "Tonight Show" host, who also is an avid New York Rangers fan, cut loose on the JumboTron during a break in the action during New York's game against the Philadelphia Flyers on Tuesday.

Fallon, clad in his Henrik Lundqvist jersey, started with sunglasses on and the hood of his sweatshirt up, but went wild and started singing along as "Start Me Up" by the Rolling Stones began to play in the arena.
That wasn't Fallon's only trip on the JumboTron though. He also jumped in when MSG introduced actress Jessica Chastain during the second period.
