In what is a flawless casting decision, Stephen Colbert is set to guest star on The Office as Andy’s oft-mentioned college a cappella buddy Broccoli Rob. Rob will appear in the Halloween episode, singing a different tune (like a cappella, BOOOM) about the history of Here Comes Treble. Tensions will rise and probably/hopefully they’ll have a sing off. And then maybe Michael Scott comes back and meets Broccoli Rob and they hit it off and decide to have a fun sort of debate they call “Even Stevphen” and it lasts forever. Best Halloween EVER.
