And, Guest 999, those books don't answer my OP point. They list or deal with jokes on what are specifically traditionally regarded as Jewish characteristics. They do not answer my query as to why a Jew would [perhaps I exaggerate, but I feel only slightly] ask the familiar first riddle we all ever heard in the form: "Why did the Jewish chicken cross the Jewish road? To get to the other Jewish side ~~ oy vey!"
