The genre doesn't really matter but it'd be nice if it can make me laugh a little.
Edit: thanks for all the suggestions!
Jon Ronson is pretty on brand for light non-fiction. The analysis is often lacking, but the stories are interesting in a gonzo journalism way and the writing style is entertaining.
Both Them! and the Men Who Stare At Goats are great fun.
its not non-fiction but anytime someone asks for a book that makes them laugh I think of the martian, the audio book at least cracked me up quite a few times, idunno if that translates to text as well but it's a great story
Light non fiction? What are you into? Get you some learning.

Oh, I seem to recall this one being very good Rocks: A Very Short Introduction Book by Jan Zalasiewicz
The first half to 2/3s of all of Brian Greene's pop science books are really, really good and easy to understand. Gives a great conceptual understanding of things like relativity and quantum mechanics. It's really not a hard read at all. At least until he gets to pushing his position on string theory, which I usually always skip but you do you. If your library has one I highly recommend checking it out.
The Ridiculous Race is pretty fun. Two tv writers race opposite ways around the world without the use of planes.
