Lionel Hutz
Lionel Hutz is a fictional character on The Simpsons television show. He is an inept ambulance chaser, that the Simpsons keep hiring as their lawyer (a fact remarked on by Marge in a typically self-aware aside). Lionel Hutz was one of the Simpsons characters voiced by Phil Hartman. The character ceased appearing in new episodes once Hartman died in 1998. Lionel Hutz works for "I Can't Believe It's A Law Firm".
In one episode he also turns his hand to selling real estate.
Some examples of Hutzisms:
Miguel Sanchez was what Lionel Hutz renamed himself as, following some trouble which prompted him to change his identity. At the time of this change of identity, he was babysitting the Simpson children: Bart, Maggie and Lisa. It is unclear how long he keeps this identity and whether or not he returns to the old one.
