Despite its name, the comedy trio The Lonely Island is surrounded by famous friends. Andy Samberg, Jorma Taccone and Akiva Schaffer are superb satirists of pop music's inherent inanity, but their cleverest move has been to let the pop stars in on the joke. "[Expletive] in a Box," their hilariously crass song and Emmy-winning video from 2006, turned The Lonely Island into celebrities precisely because it featured a real celebrity, Justin Timberlake, gamely tweaking his slick-and-sexy persona.
