Please don't make me retire. This job is what keeps me alive. I never married and my dog is dead.
―Jack Marley, at his retirement party[src]

Jack Marley is an elderly worker at the Springfield Nuclear Power Plant. His name is most likely a reference to Jacob Marley from A Christmas Carol by Charles Dickens.


He is forced to retire, even though he resists, insisting he loves his job since it's all he has left (it's implied that Mr. Burns had him retire as an excuse for him to have a party). Marge replaced him. He is still seen around Springfield showing that he stayed there after retiring.[1]

Jack with Mr. Burns

After Marge was put on trial for unintentionally shoplifting from the Kwik-E-Mart, Jack appears as the jury's foreman and states the verdict that he and the other jurors reached: Guilty (although it might be just a similar looking character).[2]

He has also been seen working as a janitor on a ship. Following Homer's court martial, as Jack is mopping passed him, he says to him, "I think you're off the hook" and Homer gives his "woo-hoo" cheer.[3]


  • In the Latin American dub, he is named Carlos Magaña after his late dubbing actor.


Note: Many of his appearances are brief, background roles. Episodes in which he has an actual role are in bold.
