Captain Underpants, book #9.

Thanks to a time machine built by Tippy Tinkletrousers (aka Professor Poopypants), we travel back in time to before Harold and George met and discover how they became friends, and, well, see the end of the world. It's the last book...until the last book comes out!

Another silly, smarter-than-it-seems installment in the hilarious Captain Underpants series. Highly recommended to kids of all ages.
