If Bart Simpson did what Nancy Cartwright did, he would probably be writing "I will not use my copyrighted voice in robocalls for Scientology" 500 times on the school blackboard.

Twentieth Century Fox television would not comment on whether Nancy Cartwright, the voice of Bart on "The Simpsons," will face disciplinary action following her voice message urging Scientologists, in Bart's voice, to attend an upcoming conference.

But "Simpsons" executive producer Al Jean makes clear that the show does not back Cartwright's call.

"This is not authorized by us," Jean said in a statement. "'The Simpsons' does not, and never has, endorsed any religion, philosophy or system of beliefs any more profound than Butterfinger bars."

The YouTube recording of Cartwright's robocall to Scientology members, which began "Hey what's happening man, this is Bart Simpson. Ha ha ha! Just kidding this is Nancy Cartwright" has been removed from the Web site.

In its place is the following wording: "This video is no longer available due to a copyright claim by Twentieth Century Fox."

Ay caramba!
