The connection between Jews, Jewish culture, and comedy in the twentieth century has long been established. The dissertation looks at Jewish comedy, comedians, and comediennes who have made the bawdy a central feature of their work. Moreover, it argues that the bawdy and the lewd have played an important role in the history of Jewish comedy and humor in the United States and in Israel. Aside from simply documenting various uses and occurrences of the bawdy in Jewish comedy, the dissertation seeks out some symptoms, as well as some underlying causes for the proclivity for such material in the work of Jewish producers of comedy by looking at historical, cultural, and personal contexts.
