Jimmy Fallon got his hosting gig off to a fine start, joining the "Glee" kids -- and Tina Fey, Jon Hamm, Betty White, Kate Gosselin, Nina Dobrev and Jorge Garcia -- for a sing-along of Bruce Springsteen's "Born to Run." We loved the number (and Betty telling Hamm to back that thing up) -- but the biggest surprise? Jimmy Fallon does a very credible Springsteen impression. Well played, Fallon.
