As has been remarked before above, jokes vary in their regional targets. They have hillbilly jokes in the west. We have Irish jokes in England. They have Polish jokes in New York --

Have you heard about the man found dead at the bottom of the Grand Canyon wearing roller-skates? The police were baffled till they found out his name was Evel Kowalski.

(I got that one from Heather Wood, who lives in NY).
