Ever since it debuted on the long-forgotten Tracey Ullman Show in 1989, The Simpsons has gone on to become a social and cultural phenomenon. The crude,
almost unrecognisable drawings we saw almost 24 years ago have gone on to become televisions most popular and instantly-recognisable characters. Spanning an unprecedented 25 series, the Matt Groening-created animation is the longest-running American sitcom, the longest-running American animated program and the longest-running American primetime, scripted TV series in history. Winner of 27 Primetime Emmy Awards, 30 Annie Awards and a Peabody Award, its main character, Homer, and his exclamatory Doh! catchphrase, has won the show a legion of fans. But of course, it isnt just Homer who makes the Simpsons such a smash-hit its the litany of co-workers, teachers, family friends, extended relatives, townspeople, fictional characters and even celebrities that lend to its charm. There are an innumerable amount of supporting characters that make up the show, a lot of them recurring, others never seen again. It's easy for the latter to fall into anonymity and become forgotten, even though they were responsible for some of the show's best episodes, and in honour of these 'one-hit wonders', here, we list the 10 Best Simpsons Characters (Who Only Appeared Once).
*For purposes of this list, characters who were central to an episode only once are considered to have made one appearance. Some of the characters listed here have appeared in later episodes, but only briefly. Special guest celebrity appearances do not count.*
