I had already bought Dirty Bertie because it was a funny book and my 2 daughters love chanting the chorus "No! Bertie! That's Dirty Bertie!". When I saw this book, I bought it without even looking at it. I knew it would be along the same lines as the first book. It is hilarious. Again my 2 daughters love it. I don't see why anyone should be offended by the words 'poot' and 'boff' to describe the passing of wind. I can think of worse words... It's not to everyone's taste - if you're embarrassed about that kind of thing, but most kids aren't and would find it highly amusing.
