The Oprah Winfrey Extended Warranty
Given recent revelations of author fraud, I wouldn't be surprised to see Barnes & Nobles, Borders, and other big book purveyors begin to offer "Truthfulness Guarantees" for purchase when buying a book. Akin to the extended warranties that places like Circuit City and Best Buy have for electronics, the "Truthfulness Guarantee" can be purchased in addition with each book. The Guarantee ensures the buyer that all statements recorded by the author as "fact" are indeed 100% vouchsafed as truthful. If the reader feels that at anytime during perusal that the author is full of shit, the book can be returned for a full refund.
