Story : Lucy bugs Ricky about getting a horse for Little Ricky and he says "no". Lucy then wins a racehorse from sending in breakfast cereal box tops. When the horse appears at the house, Ricky comes home early and Lucy, Ethel, and Fred try getting the horse up the stairs. When he finds out, he blows his top. Ricky still says no and Betty Grable comes up with a plan of getting him in a race so that Little Ricky can get the horse. Well when Lucy finds out that the horse will do anything for her only, Lucy dresses up as a jockey and rides the horse until they win the race. But will the breaking of so many rules stop them?
