I think Alan Dershowitz did some digging when he referred to the joke in one of his books.
Apparently he tracked it down to an 1890’s cartoon in a Polish newspaper and it was an anti-semitic joke not a jewish joke.
But hey, adopting your enemy’s jokes and turning them around is an old trick.
And it is a funny joke. My Dad told it to me, leaving out ethnicity I believe.
Absolutely. Many Jewish people know how to laugh at themselves.
I used to work for some Jewish people and they would tell me, “Jewish people are just like everybody else . . . only more so.”
