Dav Pilkey, the author of the Captain Underpants series, is working on a new book coming out on August 10, 2010. The title of the book is — are you ready for this — The Adventures of Ook and Gluk, Kung-Fu Cavemen From the Future.
OK, with a title like that, I don't think I even need to say any more. It goes without saying the book is going to be every bit as hilarious as Captain Underpants. I'm laughing just looking at the cover!
Speaking of the cover, what do you think is going on there? Leave a comment telling us what you think Ook and Gluk are doing and saying!
