Jean says that the Grammy-winning Waits won’t sing in the episode, titled “Homer Goes to Prep School,” but fans will recognize the singer’s trademark growl “in a second.”
The episode is expected to air sometime in December. In the meantime, Waits can also be seen in the upcoming film Seven Psychopaths, which hits theaters in October. Watch the trailer for the film here.
