The Office - Thursday October 13, 9PM ET/PT, NBC/Global

We all knew when Steve Carrell left 'The Office,' other actors and characters would move to the forefront. Tonight we get a closer look at Andy, as he throws a garden party in a bid to impress Robert. The guests include his parents, played by Stephen Collins and Dee Wallace, and by a stroke of incredible inspiration, his brother is played by Josh Groban. Prepare for some serious a cappella attitude.
