This winter, The Simpsons celebrates its 30th anniversary of being on air. That’s three “D’oh-” and donut-filled decades of Homer’s mishaps alongside Marge, Bart, Lisa and Maggie as they scheme through the years in Springfield in brilliant cartoon color. The show has also picked up a collective 31 Primetime Emmy Awards over its expansive run, making it a critical hit too. Despite the longevity of the series, none of the citizens of the Simpsons world have aged a day.
