The well-spun mock-doc sitcom puts some ho-ho-ho's and yuletide yuks in the Christmas season with a one-hour holiday-themed outing.

Better yet, this opens Dunder Mifflin's doors for one Holly Flax (Amy Ryan), Michael's true romantic flame, who returns to Scranton to cover for Toby. Talk about a Holly jolly Christmas.
