Duffman, who Lenny describes as “a guy in a costume that creates awareness of Duff,” has a booming voice and tendency to yell “Oh yeah!”
Duffman may not turn up in every episode of The Simpsons, but he’s one of the more memorable characters.
No wonder Duffman is rougher on Azaria’s voice that the likes of Carl Carlson, although I’m a little surprised Duffman beat the gravelly voice of Moe Szyslak.
After all, Homer and Co. drink a whole lot of Duff, so the appearance of Duffman can be quite the event.
