Hi Jaymie,
Thanks for your question! Yes, my Two Truths and a Lie series (co-authored with Ammi-Joan Paquette) sounds perfect! Cryptid Creatures: A Field Guide by Kelly Milner Halls also seems like it might hit the mark, as well as many of the books by Sarah Albee (Poop Happened, Bugged, Poison, Dog Days of History, Why’d They Wear That, and Accidental Archeologists. You could also try Heather L. Montgomery’s Something Rotten and Who Gives a Poop. I’d love to hear if any of these work out!

Thanks, Trudi! If I were writing this post today, I’d include all of Sarah Albee’s titles (I especially loved POISON). I also really enjoyed the Secrets of the Ancient Gods series by Vicky Alvear Shecter (Anubis Speaks, Hades Speaks, Thor Speaks).

Georgia Bragg’s books–“Caught” and “How They Croaked” have some VERY funny lines.…though maybe older kids (as well as adult readers) “get” the references. I’ve been trying to see if there are other online lists of best humorous nonfiction (picture books, middle grade, and older) or even writing classes for children’s writers who want to explore this. So far…not too much. I do agree that the illustrations (like those in Kid Presidents by David Stabler) are also so funny and are a stretch of the imagination that works.

Thanks, Bridget! I’ve actually been thinking all of the “Diary of a…” books (except for Wimpy Kid) probably belong on the list, too.
Yes, I think you’re right on about illustrations having a bit more room for humor in nonfiction than the text. I also think if we writers try to get funny with the facts, readers start to wonder if we got too funny with the facts, you know? ::winks::
