Duffman

Duffman (real name Barry Duffman or Barry Huffman) is a character on the animated sitcomThe 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".
