The Office may be over, but Ingrid Michaelson's latest video reunites a few of the actors — Rainn Wilson, Brian Baumgartner, and David Koechner — as they lip-sync and totally take over her new single, "Time Machine." The Office guys aren't the only funny TV stars there; Donald Faison, Garret Dillahunt, and Jorge Garcia (just to name a few!) are also guest stars, singing and dancing their hearts out until Michaelson takes the control back.
