Dudley Do-Right is the titular protagonist of the Dudley Do-Right segments.
Dudley was born of well-to-do-right parents in Toronto, where his father, Praise Be Do-Right, was a well-known chickpea distributor. At the DeLacey School of Good Conduct, where he was the three-time winner of the Fauntleroy Exemplary Behavior Award, he was known affectionately as "Fink" Do-Right.
Throughout Dudley's life, his goodness has shown through his every deed. Small wonder, then, that this sterling youth should turn to law enforcement for his career; and there was of course only one organization pure enough to meet Dudley's high standards—the Mounties!
Under the genial tutelage of his superior, Inspector Fenwick, Dudley has become the most implacable, incorruptible and incompetent man-tracker on the force. A stickler for regulation, Dudley is the only Mountie known to starch his underwear and socks, and to adjust his hat with a plumb-bob and mason's level.
Dudley Do-Right is a dim-witted, but conscientious and cheerful Canadian Mountie who is always trying to catch his nemesis, Snidely Whiplash, and rescue damsel in distress Nell Fenwick, his boss's daughter, with whom Dudley is deeply infatuated. He usually succeeds only by pure luck or through the actions of his horse, named "Horse". A running gag throughout the series is Nell's great affection for Horse and her disregard for Dudley.
