I Love Lucy (1951) : 5x3

Lucy thinks she may have finally gotten her big break in Hollywood. It all centers on a posh party attended by studio execs. Ricky was invited to attend but begged off. But Lucy will fool ’em. She has a lifelike rubber replica of Ricky’s head, which she’ll attach to a dummy body — and she’ll dance her way to stardom with “Raggedy Ricky.”
