A new Captain Underpants book "The Sensational Saga of Sir Stinks a Lot", comes out in August. Vine members have it for free. Your task is simple. Go to the end of the book, and see if there's a promo for a 13th book in the Captain Underpants series, tell me the title. I will personally give you 4c for free if you do this for me. Thank you in advance.
