The Lonely Island & Julian Casablancas, Boombox

The SNL digital shorts have become a weekly highlight, if only just to catch the celebrity cameos. Usually featuring Andy Samberg front and center, each video is crazier than the next. This week, in a strange twist of events, Strokes' frontman Julian Casablancas joins the ride for "Boombox," off The Lonely Island's debut, Incredibad. It's pretty epic.
