Sol says to Robert regarding his "Tappys" acceptance speech: "What if this is your Vanessa Redgrave moment?" hinting he could use the moment as a "political platform" like she did on her Oscar acceptance speech for best supporting actress for the movie Julia (1977) - the first person she thanked in her speech was her co-star Jane Fonda, who plays Grace on the show. Jane Fonda herself was also nominated for her performance (leading actress) in Julia.
Lily Tomlin and guest star Lisa Kudrow previously played mother and daughter on Kudrow's show Web Therapy.
