And this is one of the best reasons!
In this hilarious clip from the film, Franco's character Dave Skylark is interviewing rapper Eminem.
During the interview, Eminem casually comes out
OH Dave, YOU set the world on fire… with your
teatime late night chats and silly jokes!
Last night on the Late Show with David Letterman, those rowdy boys from FUN. played their
only song megahit We Are Young and David Letterman got his aging a** up on stage and raged' out!
But that would have amped this performance up a bagillion times.
Watch David Letterman NOT get in on the action (above).
And even though this song has been so overplayed it's almost unbearable, we still LURVE it!
