 As a popular comedian of the 1950s and 1960s, Walker was best known for her "telephone act" wherein she delivered a monologue to her unseen friend "Ceil" at the other end of the line.The humor of this act draws upon the Jewish stereotypes of the "overbearing mother" which had gained popularity originally in Jewish joke books after World War II.While the "Jewish mother" trope gained popularity in newer venues such as on television, in print, and on comedy albums, it is notable that she was often personified in these mediums through her "son's vision" of her.
