(Annoyed-Grunt!)

Today's featured article on WikiSimpsons:

D'oh (represented in the shows script as "annoyed-grunt") is Homer Simpson's famous catchphrase. It is used when Homer hurts himself, finds out something to his embarrassment or chagrin, is outsmarted, or undergoes or anticipates misfortune.

When Dan Castellaneta,Homer's voice actor, was first asked to voice the exclamation, he rendered it as a drawn out "doooh", inspired by Jimmy Finlayson, the moustached Scottish actor who appeared in many Laurel and Hardy films. Finlayson coined the term as a minced oath to stand for the word "Damn!" The show's creator Matt Groening felt that it would better suit the timing of animation if it were spoken faster so Castellaneta shortened it to "D'oh!"

It was first heard on a Tracey Ullman Show short entitled "Punching Bag", which aired on November 27, 1988. When Bart and Lisa try to hide a punching bag with his face on it, and it knocks him out. Homer's reaction is "D'oh!" The next occasion it was heard was in the first episodes of The Simpsons, "Simpsons Roasting on an Open Fire", airing on December 17, 1989.
