The year is 1997, Dav Pilkey brought Captain Underpants to the wonderful world of books. What started out as a little comic back in second grade, had turned into a published book. The book was very successful, so much so that every 1 or 2 years, Dav Pilkey would bless our funnybones with a new adventure up until the release of Captain Underpants and the Preposterous Plight of the Purple Potty People in 2006. At the time, Dav's father got cancer and aside from two brand new comics, it wouldn't be for 6 years that a new adventure came out. After book 9, new books came out yearly until the finale in 2015. What happened now that the Waistband Warrior has officially retired? DOG MAN.
