Every culture has a group, chosen to be the butt of inane humour.

The English tell Irish jokes;
The Irish tell Kerryman jokes;
The Americans tell Polack jokes;

We members of the folk culture tell bodhran, and banjo jokes.


...and everyone tells Morris Dance jokes ;-)


Oh! and the jews tell the best Jewish jokes. I think they are the only ones with the smarts to pre-empt others making them the butt of humour.

Newfoundlanders tell the best Newfie jokes for exactly the same reason. Thank goodness nobody ever tells any accordion jokes.
