The episode is slated to air in mid-February.

And on the Dean-low, there is more Grinder casting news to report: Jim Rash will guest-star on the Feb. 2 episode. The Community vet, who won an Academy Award for co-writing The Descendents, will play Bill Foosley, a confident owner of 20 car dealerships who is shopping around at the top law firms for a new attorney. He likes what he sees at first in Stewart (Fred Savage), but when Stewart’s brother and actor-turned-wannabe lawyer Dean (Lowe) enters the picture and starts yammering away, he has his doubts.

Rash, whose résumé contains such credits as Reno 911! and That ’70s Show, is a voice cast member of Adult Swim’s Mike Tyson Mysteries. He also will appear on an upcoming episode of The Odd Couple, and just inked a deal to co-write a horror-comedy film for Fox.

Rash and Haysbert join a Grinder guest roster that also features Christina Applegate, Timothy Olyphant, Jason Alexander, Maya Rudolph, and Colton Haynes, who plays Mitch Grinder’s son in the same episode as Rash.
