The Grinder's Dean and Stewart Sanderson may be brothers, but they are definitely not two peas in a pod.

On the new Fox comedy, Dean (Rob Lowe) is a smooth-talking big-time TV star who returns home to Boise, Idaho, after his legal series ends and decides that his TV legal know-how qualifies him to help his unassuming brother Stewart (Fred Savage) practice law in real life. That, of course, doesn't sit too well with lil bro.

Check out the exclusive videos below to see just how different the Sanderson brothers are.

The Grinder premieres Tuesday, Sept. 29 at 8:30/7:30c on Fox.
