"A 98-year-old man walks into a sperm bank."
"A guy goes to the doctor, and the doctor says, 'Look, I don't know how to tell you this, but you've just got to stop masturbating.'"
"What is the difference between a Jewish mother and Rottweiler?"
If only the Borscht Belt comedians of yore could see what they've spawned: a generation of aging Jews who have found a rabid, online, mostly younger audience who just want to hear them tell jokes. It's an idea that seems like it'd almost be too easy, but New York-based Sam Hoffman knew he had struck comedy gold when he launched Old Jews Telling Jokes in February 2009. Since then, he and his producing partners have posted over 350 jokes on their website, OldJewsTellingJokes.com; edited a book (Old Jews Telling Jokes: 5,000 Years of Funny Bits and Not-So-Kosher Laughs), published in September, that was a Los Angeles Times bestseller; and have gotten the likes of former Knot's Landing actor John Pleshette, Sesame Street writer Norman Stiles and famed graphic designer Milton Glaser to share their favorite routines. And it should come as no surprise, but old Jews (60 and over, please) seem to have a near-endless reserve of humor: Hoffman and his partners will be in Boca Raton, Florida — home to many a Jewish grandparent — on February 3, filming another round of seniors ready for their turn in the spotlight.
