This week we’re breaking down “Here Comes Treble”. Andy invites his old college a cappella group to perform at the office for Halloween but it turns sour when his rival Broccoli Rob (Stephen Colbert) overtakes the event. We hear clips from writer Halsted Sullivan and actor Nick Cafero who played a member of the “Here Comes Treble” a cappella group about their experience with this episode. Angela shares some real college a cappella group names, Jenna reveals that the ladies may have another Mom Detectives’ case to take on and the ladies bond over how this was the last Halloween episode for “The Office”. So stop bagging Meredith’s head and enjoy this episode!
