The Simpsons isn't a musical show per se, since not every episode features a musical number, but over the last three decades the show's creators have treated us to some great original songs that really get stuck in your head.
Songs like "Baby on Board", "Who Needs The Kwik-E-Mart?" and "See My Vest" stick with you seemingly for the rest of your life, lying dormant in your brain until you hear a few verses sung or read about them on a list such as this.
And let's face it- as far as earworms go I'd rather have "Baby on Board" bouncing around inside my head than some cheesy modern pop song created using the same algorithms that gave the Bieber-bot sentience.
