In their never-ending efforts to strike it rich, Lucy (Lucille Ball) and Ethel (Vivian Vance) go into the homemade-salad business. Hawking their wares on a live TV commercial, the girls are delighted when they receive thousands of orders. But their delight turns to dismay when Lucy and Ethel realize that the cost of manufacturing and packaging "Aunt Martha's Old-Fashioned Salad Dressing" far outdistances any potential profits. The solution? Do another TV commercial -- this one designed to convince the public that the girls' salad dressing is the worst product on the face of the earth.
