Duff's CEO, also known as Duff's President, was the head of the Duff Beer company.
Biography[]
When alcohol was banned in Springfield, he released Duff Zero, which is non-alcoholic. He claimed people like Duff for its taste, not the alcohol. He was wrong and Duff went out of business shortly afterwards, with him casually stating "well, that's the end of me".[1]
Behind the Laughter[]
As Duff began being sold again in later episodes and the Duff Brewery still exists it can be inferred that the repeal of prohibition in Springfield at the end of the season 8 episode Homer vs. the Eighteenth Amendment meant that Duff reopened for business. However, by season 12, H.K. Duff took the place of the CEO that introduced Duff Zero.
