Thomas Edison was a late nineteenth and early twentieth century inventor who according to Lisa Simpson invented movies, the light bulb, the phonograph, the microphone, and the electric car. After learning this, Homer Simpson researched Edison extensively. He began to obsessively tell stories about Edison throughout the day, annoying his friends, acquaintances, and relatives. Eventually he decided to become an inventor just like Edison, and to reach as many inventions as Edison created.
He learned that Edison created an undiscovered chair with two extra legs to prevent it from tipping over. Homer visited The Edison Museum to destroy it and pass it as his own invention. However, he changed his mind after learning that Edison looked up to Leonardo Da Vinci much as he looked up to Edison.
