The Simpsons ‘Duff Beer’ & ‘Flaming Moe’ Energy Drinks: You had to know this was coming sooner or later. I’m sure most people wish they were actually the beer and alcoholic mixture containing cough syrup that they are in the show, instead of the sad IRL version containing taurine and carbonation and the stuff from the inside of glow sticks. But on the plus side, this is some excellent experiential marketing – get on a steady diet of these, look like Homer in no time.
