Thomas Middleditch Thomas Middleditch

We know Dwight Schrute is bad enough as a co-worker, but imagine him as your older brother!

That's exactly what Thomas Middleditch is set to do when he debuts as Dwight's brother Jeb on The Office this fall, TV Line reports.

The Office creator Greg Daniels: "This will be the last season"

Unlike Dwight (Rainn Wilson), Jeb has no work ethic and prefers to run a pot farm rather than the family beet farm/bed and breakfast.If Schrute-centric Office spin-off The Farm goes forward, The Campaign actor will continue his portrayal of the youngest Schrute son alongside Majandra Delfino and Blake Garrett, who have been cast as Dwight's sister and nephew.The Office premieres Sept. 20 at 9/8c on NBC.  Are you excited to meet the Schrutes?
