A world without UNDERPANTS?!!!

When we last saw our heroes, George and Harold, they had been turned into evil zombie nerds doomed to roam a devastated, postapocalyptic planet for all eternity. But why, you might ask, didn't the amazing Captain Underpants save the boys from this frightening fate? Because Tippy Tinkletrousers and his time-traveling hijinks prevented George and Harold from creating Captain Underpants in the first place! Now, having changed the course of human history forever, they'll have to figure out a way to CHANGE IT BACK.
Could this be the end for Captain Underpants?!!

      The book is so good. The characters go back in time to cavemen, it's so cool to read. There's a TV show that is called captain underpants.

        This tenth book in the Captain Underpants is a whopper! In this epic novel, George and Harold (with their pets) travel back in time...To the time of the dinosaurs! They get chased by Tippy Tinkletrousers (with Captain Underpants tagging along, just for fun) and meet ... Cave-people? With the help of George and Harold, they come up with a bunch of traps to defeat the Robo-Trousers! But the cave-people soon meet a more dangerous foe... I really enjoyed this book, but did not show it in my expressions (as told to do in the book). I would recommend this book to everyone who asks me "what book should I read?"

            I can't believe what happened in this book! Captain Underpants is always saving the day from a crazy bad guy. The pictures are awesome! Captain Underpants is the best.
