In 2006, "D'oh!" was placed in sixth position on TV Land's list of the 100 greatest television catchphrases.
During the voice recording session for a Tracey Ullman Show short, Homer was required to utter what was written in the script as an "annoyed grunt". Dan Castellaneta rendered it as a drawn out "d'ooooooh". This was inspired by Jimmy Finlayson, the mustachioed Scottish actor who appeared in 33 Laurel and Hardy films. Finlayson had used the term as a minced oath to stand in for the word "Damn!" Matt Groening felt that it would better suit the timing of animation if it were spoken faster. Castellaneta then shortened it to a quickly uttered "D'oh!" The first intentional use of d'oh! occurred the Ullman short "The Krusty the Clown Show", (1989) and its first usage in the series was in the series premiere, "Simpsons Roasting on an Open Fire". It is typically represented in the show's script as "(annoyed grunt)", and is so spelled out in the official titles of several episodes. Some episodes feature variations of the word such as "Bart of Darkness", (season six, 1994) where Homer says "D'oheth" or The Simpsons Movie (2007) where Homer shouts "d'oooome!
Five episodes so far have "D'oh" in their titles (all in later seasons):
The term has also been used in popular culture beyond The Simpsons, sometimes as a reference to the program. For example, in a 2008 episode of Doctor Who, an Ood with a mark VI translator mechanism set on a "comedy classic" option says "D'oh! Another example includes Richard Dean Anderson, as Jack O'Neill, using the term himself in several episodes of his series Stargate SG-1. The Simpsons is Anderson's favorite show.
