Across 38 seasons of "The Simpsons," the Halloween-themed "Treehouse of Horror" episodes have always been a treat of spooky stand-alone storylines.

On Sunday, the show surprised viewers with a major resurrection: Apu, the beloved Kwik-E-Mart operator who had not been heard for the better part of a decade, spoke once again in Springfield.

He and his wife, Manjula, were back with a meaty plotline - and the voices of actual Indian American actors: Sunil Malhotra, a veteran voice-over artist, and Janina Gavankar ("The Morning Show").
