Duffman voiced by Hank Azaria, is the mascot and spokesman for the fictional Duff Beer company in The Simpsons. Within the series, he is a fictional character played by several people, and sometimes simultaneously. He is an athletic and smooth-talking corporate personality who wears blue and red tights, a red cape, white gloves, and the Duff logo emblazoned across his chest. The ensemble features a red hat, dark sunglasses, and a "utility belt" of beer cans around his waist. Duffman is generally known for his overly enthusiastic speech in which he refers to himself in the third person, complete with dramatic pauses and ending with a suggestive "Oh, yeah!" and pelvic thrusts. Fittingly, his theme song which plays at every corporate-sponsored appearance is "Oh Yeah" by Swiss band Yello.
