Last night, Jimmy Fallon left 30 Rock to tape a two-hour episode of "The Tonight Show" at Central Park. 1500 people showed up at Rumsey Field to watch Fallon and guests Carrie Underwood, Blake Lively and a turtleneck-wearing Henry Golding.
Fallon premiered a "Musical Photobomb" skit he and Justin Bieber filmed earlier this week in Central Park. They looked like sloppier versions of the Blues Brothers as they performed Bieber's "What Do You Mean?"
It was weird. So weird, in fact, that it was funny. Bieber and Fallon crashed a family picnic and badgered runners, all while causing only a minimum amount of mayhem.
