Some people who've purchased Boss Fight Books: Super Mario Bros. 3 have found out that while the cover of their book is spot on, the rest of it is a completely wrong.
Due to a printing error, there are copies of Boss Fight Books: Super Mario Bros. 3 that include the entire contents of Grabbing Pussy, by Karen Finley. The only part of the book that's correct is the cover! Turns out both books have the same amount of pages, paper type, and specs. They also happened to be right next to each other at the publisher, which caused a printing error. Just how many copies were impacted is unknown. It appears this issue only happened with copies purchased through Amazon, so those customers with botched copies will have to contact the online retailer for a replacement.
