This clever read-aloud book begins slyly with the suggestion that non-illustrated books seem serious and boring. But then goes on to explain that the rule of books is that anything written on the page has to be said by the person reading the book aloud. From there it's one silly, outrageous thing after another: The reader has to pretend to be a monkey then a monkey robot, has to sing a foolish song, say nonsense sounds, etc. It's good-natured, goofy fun from start to finish (with asides in the voice of the astonished reader, making the experience even giddier).
