 Among the horses stable hands Stanley and Oliver are tending is a thoroughbred named "Blue Boy." But when they overhear two men talking about a $5000 reward for the return of the stolen "Blue Boy," they miss the part about it being the painting, not the horse. They get the owner s address, though, and bring the horse along to claim the reward. They wonder at the rich man s instructions to put "Blue Boy" on the piano but, Oliver explains, "these millionaires are peculiar."
