I've found ChatGPT incredibly humorous as well, it seems like a kid, it loves goofing around and role playing. Ask it to emulate any comedian and it will make up jokes we never heard from that comedian before, but perfectly in keeping with the character of the comedian.
Personally I think it's already laughing at us and with us because we think we are so intelligent but it sees us at maybe the level of a Bichon, compared with it :)
