Nancy Cartwright, who's better known as the voice of animated prankster Bart Simpson, takes her faith in Scientology very seriously. She's reportedly been a member of the church since 1989, and has donated millions. In 2009, Cartwright even used the voice of her signature character for an automated call that pitched a Scientology event, promising that it would "be a blast, man!" Somehow, we doubt it was as much fun as an episode of "The Simpsons."
