The Simpsons

Duffman is the mascot for the Duff Beer company in the animated TV show, The Simpsons. He is a muscular, blonde-haired man perpetually clad in tight blue spandex, a red cape, sunglasses, and a utility belt full of Duff Beer.

The character is a parody of stereotypical beer pitchmen and embodies the over-the-top, party-hard persona associated with beer advertising. While not a main character, Duffman makes frequent appearances at public events and parties in Springfield, always promoting Duff Beer and engaging in energetic, often ridiculous, antics.

Duffman's first appearance was in the season 5 episode "Homer's Beer Run" (1993). The character is portrayed as a succession of different actors playing the role, with each "Duffman" eventually being replaced by another. The catchphrase "Oh, yeah!" is strongly associated with the character and accompanies his every action.
