Watch: Patton Oswalt Talks Playing Bart’s Guilt In Tomorrow’s All-New Episode Of “The Simpsons”
Patton’s been in about 50 guest appearances in animated shows, and this will be his second on FOX’s longest running animated franchise.

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”.
"There are also other characters that come and go (also owned by the Warner Bros. Discovery conglomerate media company)."
Huh. Is that just referring to other characters from the show itself, or is this implying that the new season is going to have cameos from other WBD IPs
