Funny/casual “fun-facts” books?

Not sure if “fun-facts” is the correct word here, cause I can’t figure out what exactly this genre is. But anyway, I’m wondering if anyone has any suggestions for them?

Could be about anything!
conspiracy theories of the govt (would love to find something like that), medicine, foraging, gods…etc

For example,

• The Sawbones Book: The Hilarious, Horrifying Road to Modern Medicine

• Harlots, Whores & Hackabouts: A History of Sex for Sale

Or like something like

Ghost stories but they provide historical background (Yk like those ghost hunting shows and they provide the nitty gritty gossip as to why this ghost is still here)

Or if anyone knows what this genre is called, that would be great as well!
