On our long list of favorite show theme songs, the opening number for The Simpsons is right up there at the top. It’s a fun song, it’s a catchy song, and it can be immediately recognized anywhere. You hear it and you’re like YES, time for another Simpsons episode, thank you very much. But have you ever stopped to think about how the song came to be in the first place?

In an interview with Vulture, composer Danny Elfman — who’s written scores for some of our favorite movies like, The Nightmare Before Christmas, Beetlejuice, and Tim Burton/Michael Keaton’s Batman — described how he came up with The Simpsons opening theme.

According to Elfman, it was the the “easiest” thing he’s ever written, because it came to him instantly and it stuck. “There were no notes, no changes, no suggestions,” he explains, and it all happened very fast.

Elfman didn’t think The Simpsons would last more than a season, and 27 seasons later, it’s still on the air. He composed the opener all those years ago just for “fun” and now look at where we are.

“That silly moment would become this major defining moment in my life,” he told Vulture. “It’s amazing. It’s ironic.”

Now if you don’t already have the theme stuck in your head for today, take a listen to it below. The song’s already been around for 27 years, so here’s to another 27 more.
