Jokes that don't work anymore (on a contemporary, younger crowd)

Just wondering: do kids still go to summer camp? And do they still short sheet beds? :slight_smile:

And that’s another thing! What’s the deal with all these people going for weeks (months?) to the Adirondacks? It’s the driving scenario in Dirty Dancing, but I, a Wisconsinite, just don’t get it. Why was is such A Thing? Do they still do it? And, when I got older and wiser, I ask, why is it such A Jewish Thing?

I can and did laugh at the jokes, but I don’t “get” it.
