Ask HN: How can I learn to write jokes and do comedy?

Hi, guys!! Sorry if it's a little off topic, but I figured that theres a lot of clever people here who are likely to know about that kind of thing(programming speeches and blogs are often hilarious and hackers are good at comedy). I am working on my technical blog and youtube channel, and it is very important for me to figure out how to make them funny, I also dream about learning stand up comedy, but I'm not good at it.

Does anybody here have any advice on how to learn to write jokes and do comedy? Maybe some books or courses or just ideas?

Maybe somebody has some theories about how humor works? It is important for me to understand the thing I'm doing, but after a lot of research I couldn't find any explanation of humor that would make sense.
