The stock socio/psycho/cultural/hermeneutical answer has always been that Jews have suffered a great deal through the ages and have developed a sense of humor as a defense mechanism. This doesn’t explain why, say, Chinese peasant humor doesn’t dominate prime time sit-coms or why more New Delhi untouchables don’t host more late night talk shows. Have you met a funny Tibetan lately? And why are the British so damn funny? Nine out of ten times, historically, aren’t they the heel on the back of the neck and not the other way around? OK, OK, they have that obnoxious caste system, but shouldn’t that make the Irish ten times funnier than the English?
