A book with 5000 blank pages. You really got ripped off.
Disney is doing something similar. In the gift shop of Disney Hollywood Studios, you can buy nice-looking books called "Cinderella" and "Sleeping Beauty" and "Snow White and the Seven Dwarfs". But when you open those books, all the pages are blank. They're intended to be used as journals (at least according to the cashier at that gift shop), but I can see people giving those books as gifts. The recipient gets excited to read the story-and disappointed at all the blank pages.
