The Adventures of Captain Underpants, by Dav Pilkey is a fiction book about two boys named George and Harold. George and Harold love to pull pranks. But when a prank goes to far, the principal threatens to tell everyone that they did it if George and Harold does not do everything he wants them to do. To get the tape back, George and Harold buy a hipno ring and hypnotise the principal into giving them the tap back and tell him that he is Captain Underpants, their made up superhero.

George and Harold are best friends. They have a lot in common. They live next to each other, and they are both in the some class. They also love to play pranks.

I did not really like this book, but if you like silly fun, then you should read this book.

The author of this book is Dav Pilkey. He wrote the entire Captain Underpants series. I think he made George and Harold based upon how he acted in school because he was a prankster himself.
