NEW YORK -- Bart Simpson is known for prank calls, but Nancy Cartwright, who provides Bart's voice on "The Simpsons," has been heard this week in a phone message using the voice of the cartoon fourth-grader to promote Scientology.

Cartwright, long a member of the church, recorded her 60-second robocall to boost attendance at a Scientology event scheduled for today.

Although she identifies herself, much of the spiel is delivered in Bart's voice, wrapping up with, "See you there, man!"

The Fox network would not comment, but "Simpsons" executive producer Al Jean said the message wasn't authorized by the show, which has never "endorsed any religion, philosophy or system of beliefs any more profound than Butterfinger bars."
