As a ND person I appreciate you for asking, and I appreciate how you asked, and I also appreciate that all kinds of people can benefit from an explanation to something like this right now. It's easy to misunderstand what parts of a joke are being played seriously. (caring emote)

No problem. I discovered it’s easier to just say “hey I don’t get this and I’d like to” when I can’t figure out the right social response to a joke. Took some practice but it’s saved me a lot of traumatic social situations I think.
