Why are there so many Jewish comedians? The answer is the Catskill Mountains, aka the Borscht Belt, a boot camp for the greatest generation of Jewish-American comedians. Lush farmland was turned into the 20th century's largest resort complex, the setting for a remarkable group of young comedians to hone their craft.

The honor roll is long — from old pros like Sid Caesar to "kids" like Gabe Kaplan. With narration by comedian, actor and singer Robert Klein, many return here to talk about the glory days when the Catskills were affectionately known as "the Jewish Alps."
