When Bertie and Genevieve visit the Huber's Palace Museum, they see two side-by-side (possibly conjoined) violinists playing simultaneously. The song they are playing is "Tumbalalaika," a Yiddish folk song of Russian Jewish origin. The song serves as the background music for Bertie and Genevieve's conversation about Judaism: the fact that Bertie is the only non-Jewish doctor working at Mount Sinai Hospital and the revelation that Genevieve is a Jewish daughter of Polish immigrants who changed her name from "Esther Kohn."
