Humor in nonfiction books for kids

Some peo­ple think non­fic­tion is dry and bor­ing. How can facts be fun, right? WRONG! Humor in non­fic­tion not only gets and keeps read­ers engaged, it can also help them retain the infor­ma­tion longer. My fel­low writ­ers of non­fic­tion for kids (on the NFforKids Yahoo group and on Twit­ter) and I have put togeth­er a list of our favorite FUNNY non­fic­tion titles for kids. Here’s what we came up with, in no par­tic­u­lar order:

This is just a sam­pling of our favorites. Do you have any to add? Please let us know in the comments!
I found it inter­est­ing that often the humor is pri­mar­i­ly in the illus­tra­tions, with the text play­ing it fair­ly straight. In fact, in many cas­es it’s only the jux­ta­po­si­tion of the two that tick­les your fun­ny bone. In oth­ers, the humor is mild (a smile rather than a bel­ly laugh) or is just hint­ed at rather than being an explic­it joke. Some­times, the top­ic itself is pret­ty fun­ny, but the text is fair­ly seri­ous. Giv­en how much kids love to read humor, I won­der if that’s all just coin­ci­dence, or if humor just isn’t as tol­er­at­ed in non­fic­tion texts, or maybe non­fic­tion writ­ers just don’t have a sense of humor (I’m sure not buy­ing that last one!).
