Behind the Laughter Edit
Louie's appearance and mannerisms are strongly evocative of character actor Frank Sivero, who has played gangster roles in films such as Godfellas and The Godfather Part II. Also, according to Dan Castellaneta, he modeled his voice after Italian American actor, Joe Pesci, who also had a role in Goodfellas. A reference to him is in Futurama as Clamps in the Robot Mafia.
