Wise Men of Chelm
The Wise Men of Chelm (Yiddish: די כעלמער חכמים, romanized: Di Khelemer khakhomim) are foolish Jewish residents of the Polish city of Chełm, a butt of Ashkenazi Jewish humor, similar to residents of other towns of fools: the English Wise Men of Gotham, German Schildbürger, Greek residents of Abdera, and others. Since at least 14th century Chełm had a considerable population of Jews.
