Sorry to pipe up so late here...

This is one of my favourite books (along with Walter the farting dog)
Any one of any age is ideal for it. I brought this for the library and the teachers love it so much that they read it out loud in the library at the end of their visit.

Okay if you're after a 'moral of the story' then you're outta luck as it really is that if someone poops on you, hunt them down and do the same to them.

But as something to make the kids laugh, get them enjoying reading and encourage them to read, you can't go past this book.

BTW - the reading recovery teacher at school swears by it to get the kids interested in trying to read (and we're talking 11-13 year olds here).

Plus, it's educational, I can now identify several varieties of poo.
