Hoping to audition for an upcoming movie musical, Lucy (Lucille Ball) practices an energetic jitterbug number with professional dancer Arthur "King Cat" Walsh. The rehearsal gives Ricky (Desi Arnaz) a splitting headache, necessitating a visit to the eye doctor (Shepard Menken). The trouble begins when the doctor decides that Lucy is the one who needs treatment. Thus, he applies eyedrops that temporarily blur Lucy's vision -- just when she is poised to audition with Ricky, Fred (William Frawley), and Ethel (Vivian Vance) in an elaborate "Varsity Drag" routine. ~ Rovi
