When browsing Tik Tok, one gets the impression that not much has changed since Zappa released the song in ‘82.

It was removed from the Oxford Learner’s Dictionary, but is still in the real deal, the Oxford English Dictionary.

These things seem to wax and wane. When I was young, jokes about people from New Jersey or Poland were quite common but I haven't heard either in a long time. I'm sure this is quite regional but I'm in the same region as I was when I was a child so it's interesting to see how much those have faded.

Lots of joke types have national variations.

For instance the butt of the "stupid nationality" jokes will vary by country but otherwise be the exact same joke.

I (having grown up in Essex, and moved to California) describe my home area as "The Jersey Shore of England". There's precedent in that one of the closest equivalent TV programs is named "The Only Way Is Essex".
