The Jewish joke is as old as Abraham, and like the Jews themselves it has wandered over the world, learned countless new languages, worked with a range of different materials, been performed in front of some pretty hostile crowds, and yet still retained its own distinctive identity. So what is it that animates the Jewish joke? Why are Jews so often thought of as "funny"? And how old can a joke get?With jokes from Lena Dunham to Woody Allen, as well as Freud and Marx (Groucho, mostly), Baum balances serious research with light-hearted humor and provides fascinating insight into this wellknown and much loved cultural phenomenon.
