Omicronian Priest

A minor functionary of an alien theocracy on Omicron Persei 8, glimpsed presiding over the customs and pronouncements of his gargantuan, temperamental people. He speaks with grave ceremonial authority about matters that are, on inspection, absurd — treating interstellar edicts and petty grievances with the same solemn weight.

DiMaggio's gift is deadpan bombast, and a background alien cleric is the perfect vessel for it: a booming, self-important voice applied to nonsense makes the joke land twice. Futurama thrives on these one-scene oddities who feel like they have a whole culture behind them, and he's a sturdy example of the show's throwaway world-building done right.
