There was this kid who was always goofing around, and near the very end of the book, he’s leaning against a brick house. An adult asks why he’s doing that, and he says that he’s keeping the wall from falling down. The grown-up says that that’s ridiculous, and to get off the wall right away.
So the kid does, and the wall tumbles.
I’m pretty sure it was right at the end of the book.
Anyone remember this book? I read it as a kid. It was a book that was mostly pictures, but not a comic book.
