Season 5, Episode 17: Bart Gets an Elephant
Clancy Wiggum, Springfield’s ineffective police chief, is one of the dozens of Simpsons characters voiced by actor Hank Azaria. Although Edward G. Robinson is best known for playing gangsters who have little regard for the law, Azaria has said that the voice he created for Chief Wiggum is basically his imitation of Edward G. Robinson. In the season 5 episode “Bart Gets an Elephant,” the writers included a joke about the inspiration for this character’s voice.
