Legs and Louie

Legs, voiced by Karl Wiedergott (formerly voiced by Hank Azaria), and Louie, voiced by Dan Castellaneta, are the two Springfield Mafia hitmen who accompany Fat Tony at all times. Fans often get the two confused due to neither of them having any real definitive characteristic and because they are almost always seen together. Legs has a short haircut and raspy voice. Louie has a slight afro and a more high-pitched, even squeaky tone. He says that tear gas is "[his] one weakness," though this is likely an embellishment.

Appearance
Louie's appearance and mannerisms are strongly evocative of the character actor Frank Sivero, who has played gangster roles in films such as Goodfellas and The Godfather Part II. It has also been established that Joseph Kennedy, father of President John Kennedy, had something to do with Legs acquiring his nickname, though this is never properly explained. Legs is an accomplished mob surgeon as referenced in "Trilogy of Error", where he sews Homer's thumb back on as a part of Lisa's science project.

Video Games
Louie is also a character in the video game The Simpsons Hit & Run. His map icon is two dice, and he is a source for money.
