In a Donald Duck story, Scrooge McDuck fires his old butler, and asks Gyro Gearloose to build him a new, Robotic Butler instead, believing it would be more reliable, as well as less expensive. Gyro initially delivers, but Scrooge keeps making demands for expanded features, demanding that the robot — like his old butler — be able to talk, and provide insightful commentary on day-to-day matters. Gyro is stumped, but the problem gets solved when he runs across the old, laid-off butler, who wants nothing more than to get his job back. Final solution: Gyro disguises the butler as a new robot, and the “rental and service fee” for the robot is just about the same as the butler’s old salary… the butler gets his job back, and Scrooge thinks he has an infallible robot.
