I would say this book is a cross between the Diary of a Wimpy Kid and Captain Underpants but much better. Third and Fourth graders will like this very fast read and may get good ideas for writing their own book.
The story: Ms. Wurtz, the teacher, puts a blank book in the Writing Center with only two rules: Have fun and Sign your name. The students find the book and write in it. The personality of each writer is quite obvious. Many of the entries have simple drawings to add to the light heartedness of the book. And the transition from snot to collaborative story is amazing.
