<P> Castellaneta also provides the voices for numerous other characters, including Grampa Simpson, Barney Gumble, Krusty the Clown, Groundskeeper Willie, Mayor Quimby, Hans Moleman, Sideshow Mel, Itchy, Kodos, the Squeaky Voiced Teen and Gil Gunderson . Krusty's voice is based on Chicago television's Bob Bell, who had a very raspy voice and portrayed WGN - TV's Bozo the Clown from 1960 to 1984 . Barney's trademark is a loud belch . During early recording sessions for the show, he recorded a new version of the belch for every episode but discovered that it was not easy for him to do it every time a script called for it . Castellaneta chose a recording of what he believed was his best belch and told the producers to make that the standard . Groundskeeper Willie's first appearance was in the season two episode "Principal Charming". The character was written as an angry janitor and Castellaneta was assigned to perform the voice . He did not know what voice to use and Sam Simon, who was directing at the time, suggested he use an accent . Castellaneta first tried using a Hispanic voicing, which Simon felt was too clichéd . He then tried a "big dumb Swede", which was also rejected . For his third try, he used the voice of an angry Scotsman, which was deemed appropriate enough and was used in the episode . The voice was based partially on Angus Crock, a kilt - wearing chef from the sketch comedy show Second City Television, who was portrayed by Dave Thomas . Mayor Quimby, who first appeared in "Bart Gets an F", is a parody of various members of the Kennedy family . The episode script did not call for Quimby to be a parody of them, and Castellaneta improvised the accent . Sideshow Mel's voice is Castellaneta's impression of Kelsey Grammer, the voice of Sideshow Bob . Gil is a spoof of actor Jack Lemmon's portrayal of Shelley Levene in the 1992 film adaptation of the play Glengarry Glen Ross . Show runner Mike Scully thought that Gil would be "a one - shot thing" but "Dan Castellaneta was so funny at the table read doing the character, we kept making up excuses in subsequent episodes to put him in ." The Blue - Haired Lawyer's voice, as well as his demeanor, is based on lawyer Roy Cohn . </P> <P> Castellaneta has won several awards for voicing Homer, including four Primetime Emmy Awards for "Outstanding Voice - Over Performance" in 1992 for "Lisa's Pony", 1993 for "Mr. Plow", 2004 for voicing several characters in "Today I Am a Clown", and 2009 for voicing Homer in "Father Knows Worst". In 1993, Castellaneta was given a special Annie Award, "Outstanding Individual Achievement in the Field of Animation", for his work as Homer on The Simpsons . In 2004, Castellaneta and Julie Kavner (the voice of Marge) won a Young Artist Award for "Most Popular Mom & Dad in a TV Series". Homer was placed second on TV Guide's 2002 Top 50 Greatest Cartoon Characters, and in 2000, Homer and the rest of the Simpson family were awarded a star on the Hollywood Walk of Fame located at 7021 Hollywood Boulevard . </P> <P> Until 1998, Castellaneta was paid $30,000 per episode . During a pay dispute in 1998, Fox threatened to replace the six main voice actors with new actors, going as far as preparing for casting of new voices . The dispute was soon resolved and he received $125,000 per episode until 2004 when the voice actors demanded that they be paid $360,000 an episode . The issue was resolved a month later, and Castellaneta earned $250,000 per episode . After salary re-negotiations in 2008, the voice actors received approximately $400,000 per episode . Three years later, with Fox threatening to cancel the series unless production costs were cut, Castellaneta and the other cast members accepted a 25 percent pay cut, down to over $300,000 per episode . </P> <P> In the early 1990s, Castellaneta and Deb Lacusta wrote a script for an episode in which Barney becomes sober . They pitched their idea to showrunner Al Jean . Jean liked the story, but turned it down because he felt that it was too similar to "Duffless", an episode that the writers were already working on . They waited several years and offered their script, which they updated, to then - show runner Mike Scully, who liked it and had them make a few changes . Their script became the eleventh season episode "Days of Wine and D'oh'ses", which first aired April 9, 2000 . Castellaneta and his wife have also written the episodes "Gump Roast", "The Ziff Who Came to Dinner", "Kiss Kiss, Bang Bangalore", and "The Fight Before Christmas". In 2007, they were nominated for a Writers Guild of America Award for the episode "Kiss Kiss, Bang Bangalore". Castellaneta is also credited as a consulting producer . </P>
