Synopsis by Hal Erickson
This episode is not only a reworking of The Lucy-Desi Comedy Hour featuring Betty Grable and Harry James, but it also represents the first season-four appearance of Ann Sothern as the Countess Framboise, otherwise known as Lucy's old school pal Rosie Hannigan. Showing up at Lucy's doorstep with plenty of luggage but no money, the countess confesses that her sole possession is a pregnant race horse named Oil Well left to her by her late husband. Instantly, Lucy (Lucille Ball) hatches a scheme to help both the countess and the horse -- with the unwitting aid of Mr. Mooney (Gale Gordon). (William Frawley), the immortal Fred Mertz of I Love Lucy fame, makes his last-ever TV appearance in this episode.
