Mervin Monroe - Duffman

Duffman, voiced by Hank Azaria, is a recurring character, who according to Turner, "embodies all the self-importance and over-statement of contemporary marketing." He is the mascot for the fictional Duff Corporation that sells Duff beer, and is based on Budweiser's former mascot Bud Man. Duffman is a muscular actor, dressed in a superhero costume who spouts slogans while he thrusts his hips. Duffman's thrusts were first acted out by Brad Bird. His catchphrase comes from the song "Oh Yeah" by Yello, which the producers say became extremely popular after Ferris Bueller's Day Off and many advertisers started using it. As a result, the writers felt that the song and phrase "Oh yeah!" would be a suitable leitmotif for the character. While usually loyal to his corporate sponsors, in the season 15 episode "Co-Dependent's Day", Duffman reveals he is ashamed of betraying his Jewish heritage by doing a Nazi-esque performance at Oktoberfest ("This reich will last a thousand beers! Oh, ja! : I do this, and I'm Jewish."). In the season 17 episode "Marge and Homer Turn a Couple Play", it was revealed that there were two more Duffmen working (but it's kept a secret so as not to disillusion children) and "Jaws Wired Shut" (from season 13) revealed that all the actors who have played Duffman have died ("Duffman can never die; only the actors who play him"), which sheds some light on the so-called continuity error in which Duffman was referred to as "Larry" in "Pygmoelian," but in "Hungry, Hungry Homer," Howard K. Duff called him "Sid."
