A critic once wrote of Stuart, when he was acting the role of Frankenfurter in The Rocky Horror Picture Show, that he had spindly legs. The same critic wrote that Mark Hadlow, as Riff Raff, was too fat for the role. The next night, in a scene where Stuart had to wrest a whip from Hadlow, Hadlow refused to give it up. "Give me the whip, Fatty," Devenie improvised, loudly. The audience loved it, and the critic was silenced.
