It may not sound like much, but take my word for it. An elderly man reciting the lyrics of “Ol’ Man River” in a Yiddish accent is one of the funniest things to be found on a New York stage.

It’s one of the many highlights of Old Jews Telling Jokes, the blunt title of which is only partially true. The five-person cast also includes two younger members who more than keep up with their elders.

This 80-minute joke-a-thon is the brainchild of Peter Gethers and Daniel Okrent, the latter of whom recently stepped down from his position as public editor of the New York Times. It’s based on a popular website, but you shouldn’t pass up the opportunity to kvell in person.

The concept couldn’t be simpler. Three seniors—Lenny Wolpe, Marilyn Sokol and the priceless Todd Sussman—tell a series of jokes, some hoary but all hilarious, about such topics as sex, marriage, old age and death. They’re ably supported by the comparatively junior Billy Army and Audrey Lynn Weston, as well as pianist Donald Corren who provides accompaniment for the occasional musical number.

The minimal staging includes animated projections and a hilarious film clip of Alan King delivering his classic “Survived by his wife” routine. But really, the jokes are the thing, and they come fast and furious. You may have heard some of them before, such as this chestnut: “Why do Jewish mothers drink? To dull the pain.” But even if you have, you’ll laugh anew.

It’s tempting to simply quote the funniest bits. But that would spoil the fun. Suffice it to say that the material, ranging from one-liners of the Henny Youngman variety to skits involving such things as a embarrassing public passing of gas and a man who falls in love with his sheep (uproariously impersonated by Sokol), is consistently uproarious.

The performers have their varied strengths. Wolpe provides a sly, avuncular gentleness; Sokol a vaudevillian physicality; Army a protean clowning; and Weston a deceptive sweetness that makes her sometimes obscene material that much funnier.

But the real MVP is the bespectacled Sussman, whose subtle delivery and masterful timing infuses every routine, including the aforementioned song recital, with comic brilliance.

Best of all, you don’t even have to be Jewish to enjoy the fun, although, as they say, it wouldn’t hurt.
