Duncan, also known by his nickname Furious D, is a racehorse.


Bart rescued him from a fair, where he was forced to jump off a diving board.

Bart and Homer then trained him as a racehorse, building his confidence and giving him the persona of "Furious D". With Bart as the jockey, he became very successful, winning a large number of races at the Springfield Downs.

After winning the championship race, Duncan retired to live out his life as a stud.
