A holiday-themed parody of "Glee" in which Abed tries to persuade each member of the Study Group to join the glee club so that they can qualify for regionals.
When the Greendale Glee Club is unexpectedly sidelined, the school's effervescent choir director Cory Radison sets about recruiting the study group members to fill in. Skeptical at first, they eventually fall under his hypnotic spell - one-by-one - singing and dancing their way to the annual Christmas Pageant.—NBC Publicity
