I have a joke about food, but not everyone will get it

I have a recursion joke. Re-read this for the punchline.

I have an unemployment joke but it doesn’t work.

I have an education joke but it requires more testing.

I have a resolution joke, but I can’t read it.

I have a forgettable joke, but can’t remember it.

I have a history joke, but I can’t find my source.

I have a geology joke but it isn’t very gneiss.

I have a battery joke, but it won’t charge.

I have a philatelist joke, but I can’t post it yet

I like how the jokes get progressively better the more layers you go away from the original post
