Homer says "D'oh!"

Just when you thought there were enough Simpsons lists, here comes the mother of them all... the definitive D'oh list! I created this list and I maintain it here and at The Simpsons Archive (though this page will always be the latest version). I have included other characters as well as Homer in this list as well, so unless otherwise stated, the character saying "D'oh!" is Homer.

The origins of D'oh!

Matt Groening initially conceived it as an "annoyed grunt," and it is still written that way in most Simpsons TV scripts. In fact many titles that feature the word D'oh are referred to as annoyed grunt, for example, E-I-E-I-(Annoyed Grunt).

"D'oh!" originates from the Laurel and Hardy films. Dan Castellaneta (the voice of Homer) was inspired by Jim Finlayson, who said "doooooh" (long and slow) whenever something angered him. However, Matt decided that to suit the speed of animation, it would be better said faster. And so, D'oh! was born.
