Remember when everyone was filming themselves lip-synching to their favorite song? As the "cold open" for the first episode of its new season on NBC, the cast of The Office brought back the "lip dub" trend, moving around the Dunder Mifflin office while lip-synching, tossing streamers and brandishing a knife (yup, that would be Dwight). Even if you don't watch the show, anyone can appreciate Steve Carell's bug-eyed magic tricks.
