“He had a hat.”
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.
ROFLMAO!! You must have been listening to Henny Youngman on XM 151.
