 Other Duff Gardens attractions include the Beeramid, the Beerquarium ("Home of the world's happiest fish"), the Beer Hall of Presidents, the Washing Machine ride, the Whiplash rollercoaster, singing group Hooray for Everything (who sing a politically correct version of Lou Reed's "Walk on the Wild Side" and are based on Up with People), and a direct parody of Disneyland's Main Street Electrical Parade.There have speculation that the name was inspired by one-syllable beer names in the United States (such as "Bud"), and "The Simpsons"' writers had found the name humorous.However, longtime Simpsons animator, producer, and director David Silverman stated in 2012 that Groening named the beer "Duff" simply for the convenient rhyme in the slogan "Can't Get Enough of that Wonderful Duff".
