Jewish humour
Jewish humour is the long tradition of humour in Judaism dating back to the Torah and the Midrash from the ancient Middle East, but generally refers to the more recent stream of verbal and often anecdotal humour of Ashkenazi Jewry which took root in the United States over the last hundred years, including in secular Jewish culture. European Jewish humor in its early form developed in the Jewish community of the Holy Roman Empire, with theological satire becoming a traditional way of clandestinely opposing Christianization. Modern Jewish humor emerged during the nineteenth century among German-speaking Jews of the Haskalah (Jewish Enlightenment), matured in the shtetls of the Russian Empire, and then flourished in twentieth-century America, arriving with the millions of Jews who emigrated from Eastern Europe between the 1880s and the early 1920s.
Beginning with vaudeville, and continuing through radio, stand-up comedy, film, and television, a disproportionately high percentage of American, German, and Russian comedians have been Jewish. A Psychology Today study estimates that 80% of American professional comics are Jews.
