Episode based on the 2016 studio album "Lemonade" by Beyoncé.
When Lillian and Jacqueline see that Kimmy is the only eligible voter in the district, Jacqueline says she needs to get Kimmy to vote for "anyone but you" (addressing Lillian). This is a reference to the anti Christine Quinn activist group during the 2013 NYC Mayoral race whose catch slogan was "Vote For Anyone But Christine Quinn".
When Lillian yells "Liar!" at Jacqueline, Carol Kane repeats her own famous line from The Princess Bride.
