Lucy's friend Caroline Appleby (Doris Singleton) arrives in Hollywood, demanding to meet some of the celebrities with whom Lucy has claimed to be so chummy. First on Caroline's list is Van Johnson, whom, of course, Lucy has never met. Our heroine manages to get herself into a hole by inviting Caroline to watch a rehearsal of a dance act that Lucy and Johnson are purportedly performing at the Beverly Palms Hotel nightclub, taking advantage of the fact that the nearsighted Caroline has lost her glasses and won't be able to see anything. When the glasses are located, a desperate Lucy begs Johnson to bail her out -- and the result is an astonishing display of the terpsichorean skills of both Van Johnson and Lucille Ball, to the accompaniment of the old standard "How About You."
