It's the Mertzes' eighteenth wedding anniversary. Ethel longs to celebrate it by going to the Copacabana, while Fred wants to attend the fights. As can be guessed, an argument soon ensues among the couples. Ethel and Lucy decide that they will go to the club-with dates! Now, this is perfectly fine with Fred, but Ricky is worried. So he and Fred call an old friend, Ginny Jones, for dates so that they can go to the nightclub and spy on their wives. Coincidentally, Lucy and Ethel have also called Ginny about getting dates to go to the club. When Ginny tells the girls about the boys' plans, Lucy decides that she and Ethel will impersonate the boys' blind dates. Thus, the two of them enter the Ricardo apartment decked out like country bumpkins, which makes for some superb Lucille Ball schtick.
