So, I'm writing this scene between two characters in which one is reading from a jokebook he has to the other, which is actually a very old nature spirit. I have it so the jokebook guy is going to read two jokes from the book while the nature spirit recites one joke from memory.
The jokebook guy should be telling some sort of socio-political joke that should be relatable to the modern era. However, since this is an alternate fantasy universe, it also needs to be vague enough to fit in there too, so no references to particular individuals such as Hillary or Trump will work. Anything related to civil servants or intellectuals is my best bet. Here is one joke I was thinking of using for the jokebook guy: A biologist, a chemist and a statistician go hunting. When they see a deer, the biologist shoots first and misses five feet to the right. Then the chemist tries and misses five feet two the left. "We got it!" says the statistician.
The nature spirit is a bit trickier. It needs to be something a bit more timeless or out of date. I've been looking at medieval jokes, but a lot of the are too "human" actually. I might have to come up with something unrelated to human society for this one actually. It should perhaps sound like a riddle, but it also needs to have some sort of punchline to be a joke.

PEACE Disciple: Oh wise and all knowing one, take me to the realm of perfect peace. Master: If I take you to that realm, it will no longer be peaceful.
p.s. I would love to read your story if at all possible when you are ready to share it.
Lol, thank you.
I'm thinking I should post it online for you and any others who'd be interested, just haven't decide where yet.

Dunno if it'll fit in with what you're writing (maybe you can tweak it a little if your story has multi-limbed beings? ) but one I love retelling is:
How many tickles does it take to make an octopus laugh? Ten! Ten-tickles!
Super cheesy, always good for a groan, especially once the pun/ punchline hits the listener, but that's why I love it.
