So, never mind the last part, being chased by Tippy Tinkletrousers (the former Professor Poopypants). This book starts off interestingly, ending up with a few kids in juvie and a principal behind bars, but not for long. And anyway, this isn't a book about Captain Underpants this time. Instead, it goes back to when George and Harold were kids, right when Act Two begins. Why? Before I tell you that story, I have to tell you this story, as Dav Pilkey always says. There are four bullies, led by Kipper Krupp. Yep, he's related to Mr. Krupp.George and Harold decide to take a stand against the bullies, not forcefully, that won't do anything. What they have to do is use his stupidity, and trick him prank-wise into thinking a ghost is cursing them for being bullies. In the end, it's a lesson in why time travel needs to be carefully used.
George and Harold find a way to hide their stuff in the school, get into Kipper's locker, and not just prank him, but let his posse laugh while scaring them as well.
Of course, there are the occasional jokes that are only for toddlers, but not that much for a Captain Underpants book. What I liked most about this was it was actually intense, because the pranks were super clever. They get into his locker by playing a super original trick with his lock. Another thing I loved is that it answers unanswered questions you may not even know you had, like how George and Harold met, why George wears a tie to school all the time, and even why George has such short hair. Every Captain Underpants book is in the series for a reason rather than just being there to annoy adults who have to read it to kids who can't read. Of course, the first book created the hero, Book 2 is why the boogers in Book 7 were able to come back home, Book 3 is how Captain Underpants got his powers, Book 4 creates the villain for Book 9, etc. The reason for this one, however, is simply to delight people like me who have waited so long.
