The song was partly inspired by Wilson's obsession with physical fitness in the late 1960s. In a contemporary article, he stated, "I want to turn people on to vegetables, good natural food, organic food. Health is an important element in spiritual enlightenment. But I do not want to be pompous about it, so we will engage in a satirical approach." Another reported inspiration for the song was a humorous comment Wilson heard about the effect of marijuana turning him and his friends into a "vegetative" state.
