How many former “Daily Show” correspondents can you get on one show? Well on the Halloween episodes of “The Office,” the answer will be two. Entertainment Weekly is reporting that Stephen Colbert will guest start on the NBC comedy in October, alongside Ed Helms — both are alums of the Jon Stewart mock news show. Colbert, known for his work on the “Daily Show” and his own show “The Colbert Report,” will play an album Here Comes Treble, Andy’s (Helms) a cappella group from Cornell. The episode will air on Oct. 25.
