Duffman

Barry Huffman, more commonly known by his work name Duffman, is a character on the animated sitcom The Simpsons. He is the mascot and chief spokesperson for Duff Beer. It has been referenced, however, that the corporate mascot "Duffman" has actually been embodied by a number of different actors, though they are virtually identical. He is known for his staccato catchphrase: "Oh, yeah!" (also the character's unofficial theme song). He is recognizable by his "Duff"-branded cap, wayfarer sunglasses, red cape, light blue bodysuit, and utility belt stocked with "Duff".
