David Harbour will appear in an “Undercover Boss” style episode of The Simpsons. According to EW, the episode will have Harry Shearer’s Mr. Burns spot some insulting graffiti on the wall of his nuclear power plant. He then decides to go “undercover,” with “a whole new body and face and voice so that the people in the plant won’t possibly recognize him.”

The episode will be a part of the 32nd season of The Simpson. Season 31 is currently airing, following its premiere in September, 2019.

It was also announced that Cate Blanchett will be voicing a character in an episode that will “likely serve as the season 31 finale.” She will play a canine psychologist named Elaine, who will be working with Homer’s dog, Santa’s Little Helper.

The Simpsons is currently airing on Fox on Sundays at 8/7c.
