After Ricky and Fred get upset about the girls' spending and bounced checks, Lucy and Ethel challenge the men to swap roles for a week. The girls go to work while the boys do housework. Lucy and Ethel end up at Kramer's Kandy Kitchen, where they struggle hilariously in the candy-dipping department and then are assigned to the wrapping department. On an assembly line conveyor belt, they must wrap chocolates as they pass by. When the forewoman speeds up the belt saying "Let 'er roll!", chaos ensues as Lucy and Ethel frantically try to keep up, eventually stuffing chocolates in their mouths, hats, and clothes. Meanwhile, Ricky and Fred completely fail at cooking and housework. This features one of the most iconic scenes in television history - the chocolate factory conveyor belt scene.
