“Recently, I’ve been looking at the oldest episodes and realizing, God, there was so much happening,” The Simpsons star said on the podcast I Think You’re Interesting. “The look of the show, it’s changed so much, because of the introduction, decades later, of digital (animation), but even our voices. People have asked me, ‘Do you think Bart’s voice has changed over the years?’ And I say, ‘No, I don’t think so,’ but it actually has.”
