When I first saw this video I thought Jimmy Fallon was doing some sort of a Brady Bunch parody. Turns out it's much better. It's Jimmy and friends, including The Roots, Carrie Underwood, Sam Smith, Ariana Grande, Blake Shelton, Usher, Meghan Trainor, One Direction and Christina Aguilera all singing the Queen classic "We Are The Champions".

I'm guessing they dedicated this one out to the New England Patriots after their miraculous Super Bowl victory.
