John Krasinski, Rainn Wilson

After eight years of hilarious pranks, awkward office parties and conference room meetings gone horribly awry, The Office is getting ready to close its doors for good. And from the looks of things, the NBC comedy isn't going quietly (after all, when has anyone done anything quietly at Dunder Mifflin?).

In this exclusive sneak peek of the final season, fans will meet the new Dwight (Rainn Wilson) and Jim (John Krasinski), aka the new guys (Clark Duke and Jake Lacey). Plus: The new promo teases the return of old friends and "surprises like only The Office can pull off."
