What is the name of Homer Simpson's favorite beer?

If you ever get the chance to visit the Springfield zone at Universal Studios, you can grab a Krusty Burger, a Lard Lad donut, and then wash it all down with an ice-cold Duff Beer. The brand showed up all the way back in 1990 during the first season as a jab at mass-market American lagers. They doubled down a few years later with the introduction of the Duffman mascot, a cape-wearing spokesman in mirror sunglasses who screams "Oh Yeah!" at every opportunity. It might be a joke beer, but Time magazine decided it had real power when it called it one of fiction's most influential companies.
