Arthur Perkins

Arthur Perkins turns up in the world of Rentaghost as one of the ordinary humans caught up in the agency's peculiar business, a steady, unflappable presence amid haunted furniture and eccentric spirits. He goes about his day with mild exasperation and patience, treating the supernatural chaos around him as just another thing to be managed.

Jeffrey Segal plays him with a dry, grounded calm that gives the sitcom's silliness something solid to bounce off. Arthur's ordinariness is the joke's straight edge — his refusal to be rattled by ghosts and floating props makes the absurdity funnier, and his presence keeps Rentaghost's whimsy tethered to something recognisably human.
