What animated character loves to say "D'Oh"?

The animated character famous for saying “D’oh!” is Homer Simpson.

Homer is the bumbling father of the Simpson family in Matt Groening’s animated television series The Simpsons. He typically exclaims “D’oh!” after hurting himself, making a foolish mistake, or realizing that something has gone wrong. The short expression became one of television’s most recognizable catchphrases and is strongly identified with Homer’s comic frustration.

Voice actor Dan Castellaneta created the sound during recording for The Tracey Ullman Show shorts. The script described it as an “annoyed grunt,” and Castellaneta drew inspiration from comedian and actor Jimmy Finlayson, who used a similar exclamation in Laurel and Hardy films. Matt Groening wanted a faster delivery, leading to the clipped “D’oh!” used in the series.

The phrase first appeared in a Tracey Ullman Show short before The Simpsons became a half-hour series. Its first use in the regular show came in the 1989 episode “Simpsons Roasting on an Open Fire.” Other characters occasionally say it, but Homer remains its canonical speaker. The spelling was initially represented in scripts as “annoyed grunt,” which is why the exact written form came later.
