I won this book from a giveaway, so thank you iDOGO! This book truly DOES have "everything you always wanted to know about everything!" Want to learn about the basketball that records every dribble and shot you make? No problem! Running out of corny jokes to annoy your family with? Not anymore. I betcha you never knew how to survive a Killer Bee attack ( I already did, but still). Well, you will know now. Every time I flip through the pages I find something new. Great for all ages and anyone who wants to learn about EVERYTHING.
