Oh, The Simpsons...has it been that long? Are these figures produced by Kidrobot actually a thing? Were they part of a storyline on The Simpsons, or is this simply some sort of artistic liberty taken with the Duff Beer label?
Nonetheless, Kidrobot has released a pair of 3-inch tall minifigures from their "The Simpsons" line. Dizzy Duff and Surly Duff are the first two figures from The Faces of Duff series to be released. They're currently available for $14.99...or, I'm assuming, around the price of a case of actual Duff Beer...minus the personality.
