While their husbands are otherwise occupied, Lucy (Lucille Ball) and Ethel (Vivian Vance) take a bus sightseeing tour of Los Angeles. When the bus pulls up near the home of actor Richard Widmark, Lucy announces that Widmark and her husband, Ricky (Desi Arnaz), are at that moment having lunch together. This announcement neatly foreshadows the hilarity to come when, in her efforts to swipe a souvenir orange from Widmark's backyard, Lucy falls over the fence and is trapped on the actor's estate. Ultimately, Widmark and Ricky show up to have lunch -- whereupon Lucy adopts what may be her most ridiculous disguise ever. This was the final episode of I Love Lucy's fourth season. ~ Rovi
