I was always told to not say anything if I didn't have anything nice to say. That being said, I'm not completely sold on Jimmy Fallon's ability to host an entire 90 minute show on his own. Once he takes over the "Late Night" position for Conan O'Brien next year, at least we'll all have the pleasure of knowing that his house band, The Roots, will be proper and tight. Most of the clip below consists of Fallon introducing the public to his new set at NBC in New York City, but if you go to end of the clip, you'll see The Mighty Roots crew in action.
