Bart Simpson shills for Scientology

And Bleeding Gums Murphy is rolling in his grave.

Nancy Cartwright, the voice of Bart Simpson (and Ralph Wiggum and Nelson Muntz) is a longtime Scientologist. She’s reported to have given much dinero to the controversial organization.

FOX brass are said to be fuming at this little misallocation of intellectual property.

"The Simpsons does not, and never has, endorsed any religion, philosophy or system of beliefs any more profound than Butterfinger bars," said executive producer Al Jean.

Meanwhile, Simpsons fans are pissed.
