Can you grind too hard? Stewart apparently thinks so.

On Tuesday's The Grinder (9:30/8:30c, Fox), which kicks off Maya Rudolph's four-episode stint as Dean's therapist, Stewart (Fred Savage) confronts Dean (Rob Lowe) about taking his grinding down a notch, since his TV melodramatics don't really have a place in an actual courtroom.

"When you say stuff like, 'The Grinder never settles' ... I know that about him and I love it, and that's great for a TV character," Stew says in the exclusive sneak peek below. "Problem is, in real life, lawyers settle. A lot."

Check out the rest of the clip to see how Dean reacts. The Grinder airs Tuesdays at 9:30/8:30c on Fox.
