The Simpsons will premiere an all-new episode tomorrow evening @ 8 pm ET/PT only on FOX entitled  “The Cad and the Hat”. In it, when Bart betrays Lisa, he has to deal with his guilt – literally. Meanwhile, Springfield is in awe when Homer is revealed to be a chess savant.

Both plots will feature guest stars, with Homer’s bit featuring Grand Chess Master Magnus Carlsen and Bart’s tale featuring guest star Patton Oswalt guest-starring as Bart’s “Guilt”. Patton took park in a featurette for FOX where he offers up additional details on his guest spot and what we can expect in this upcoming episode.

This isn’t the first-time that Patton Oswalt has guest-appeared on The Simpsons. Patton previously voiced the role of “T-Rex” in an episode entitled “The Day the Earth Stood Cool”.
