You might have heard of a little show called “The Simpsons.”

Like Marketplace, the show turns 25 this year. Let’s do the numbers: “The Simpsons” premiered on December 17, 1989. It’s still going strong at 557 episodes and Hank Azaria has voiced at least 100 characters like Moe the bartender, Chief Wiggum, and Apu.

Listen to the full conversation with Azaria, from our stage show “How I Learned to Stop Worrying and Love the Numbers,” in the audio player above.

Marketplace’s road show wraps up in Los Angeles Saturday, November 8.
