      "bio_text": "Lionel Hutz is a recurring character in the animated television series The Simpsons. He was voiced by Phil Hartman, and his first appearance was in the season two episode \"Bart Gets Hit by a Car\". Due to the death of Hartman, his final speaking role was in the episode \"Realty Bites\". Hutz is a lawyer in Springfield, albeit an incompetent one who is always desperate for cases, few of which he wins. It is not known whether he truly went to law school or not. He claims to have gone to Princeton Law School, in spite of the fact that Princeton University does not have a law school. Hutz is often depicted as being financially unsound, extremely poor and willing to do anything for cash.",
