Yes, her. Nancy Cartwright has been the voice of Bart Simpson on the longest running sitcom in TV history since it began in the 90s. 

You have to wonder what took her so long to start her own podcast, called "Simpsons Declassified." The first one dropped this week and with such a long running show, she's expecting hundreds more will follow, spilling secrets about the behind-the-scenes goings-on of the comedy.

"Episodes will feature untold stories, near-cut scenes, how Bart began mirroring Cartwright's real life, and the surprises that still catch her off guard. The series will also tackle the show's most talked-about "predictions" and enduring fan conspiracies, with themed games and appearances by guest stars, writers, directors, and notable fans."
