The Chain Smoker

He turns up on the margins of New New York, a background face glimpsed in crowds and diners, cigarette perpetually lit. Nobody introduces him properly; he's just there, puffing away with total indifference to the chaos of the future unfolding around him, a running visual joke rather than a character with a stated goal.

Futurama built half its charm on throwaway faces like this one, and giving him to John DiMaggio — a voice actor who can make a single line land — turns a sight gag into something with actual comic texture. He works because the show trusts a joke this small to be funny purely on repetition and deadpan commitment.
