This book is great for little boys or boys of all ages.Its full of the horrible dirty things that boys find funny.<br>I've just bought this for my 6 year old son for christmas and after looking through it,I know hes going to love it.<br>Its factual but in a funny and filthy way if you know what I mean.<br>Very entertaining.<br>Well worth buying.

My grandsons are into yucky things. They now have a pile of the Yuck Encyclopedia, Yuck's Fart Club, Yuck's Big Bogeys, and Gross Records - and they are in heaven. Excellent stuff for just baout eny child in my opinion.

This book is great.<br>It is fully of really interesting stuff the seven year old boy inside is us all wants to know. <br>I loved the stuff about how shrunken heads were made (I'd always wondered about that).<br>My son loves this book too, the idea of pee being cleaner than spit has had him re-reading that page time after time.<br>Buying this book was a great way to find out loads of vital stuff we couldn't live without. I have bought loads of copies now as this is a brilliant birthday pressie for a child aged 6-10.<br>The book is very american in it's language and picture style but you soon get over that and it's not a problem.
