Duff (magazine)

Duff is a magazine about Duff Beer.

History
When Bartman accidentally created robot versions of the family they fled, leaving a trail of destruction towards the Kwik-E-Mart. They were reading magazines, much to Apu's annoyance, who was insisting the magazines were for buying only. Barium, reading a  comic, insisted they were still thinking about purchase. At the same time, Holmium was reading an issue of Duff.
