FREE, advance registration encouraged In partnership with the Herbert D. Katz Center for Advanced Judaic Studies at the University of Pennsylvania Is there a definition of Jewish humor?

Jeremy Dauber, director of Columbia's Institute for Israel and Jewish Studies and author of a recent biography on Sholem Aleichem, will answer these and many other questions in a wide-ranging talk on Jewish comedy's long and wide reach over two millennia—and will tell the greatest Jewish joke in history into the bargain. (At least in one man's opinion.)
