In this classic episode, Lucy (Lucille Ball) once again goes to extreme lengths to appear in Ricky's nightclub act. Apprised that Ricky (Desi Arnaz) is looking for a ballerina and a burlesque comic, Lucy first takes ballet lessons from the imperious Mme. LaMond (Mary Wickes) -- and ends up with her foot stuck in the practicing bar. Next, Lucy persuades a baggy-pants comedian (Frank J. Scannell) to teach her the vintage burlesque chestnut "Slowly I Turned," replete with custard pies and seltzer water. Inevitably, Lucy shows up in the middle of Ricky's act at the Trocadero -- little realizing that this is the evening that the ballerina, and not the comic, is supposed to appear. Desi Arnaz sings "Martha." ~ Rovi
