Production of Wish It, Want It, Do It started immediately after the ultimate failure of Brian's first book, Faster Than the Speed of Love. Unlike with his first book, Brian actually started and finished his novel in record time, as was written entirely, throughout the beginning of the episode, "Brian Writes a Bestseller", and was published by Penguin Group. He started writing it after receiving unsold copies of his bomb Faster Than the Speed of Love, which almost drove him to quit writing. At home, he wrote the book in a day. The book ranked #3 on Amazon.com's bestseller list. Brian wrote it as a stealth insult to self-help books in general, and completed it in three hours. It had fifty blank pages in the middle for the reader to fill in on their own.
During his book tour, Brian appoints Stewie as his publicist. He also visits bookstores for book signings, which he uses to pick up female fans. He promotes the book on shows such as Quahog 5 News and Real Time with Bill Maher. By the time he appears on Real Time, Brian's fame had gone to his head and fired Stewie. On Real Time Bill Maher, Arianna Huffington and Dana Gould criticize the book, forcing Brian to admit his opinion that it's crap and his desire to write something that would sell. At this point, Bill loses all respect for Brian and shames him for not standing by his beliefs. This causes Brian to urinate and Bill sends him outside with a newspaper. However, the effects of the book's success still linger when Brian "apologizes" to Stewie but in fact blames him. To counterpoint, Stewie says that Brian can't write.
