Bookstore Employee Feels "Pride And Prejudice" Probably Not A Book

A bookstore employee asked to assist a customer in locating a copy of "Pride and Prejudice" stated that she didn't think it was a book. She offered that she knew it was a movie, and that the movie had been adapted from something, but she didn't remember it being a book.
The customer stated that although she did not know the name of the author, the text was required for a class her son was in so she felt certain it must be a book. Together they searched the shelves unsuccessfully until the customer relented and thanked the employee for her help. The employee then suggested that perhaps she should check the database before they called off their efforts. Upon discovering that in fact "Pride and Prejudice" was a book and available in the store she offered the following response:
What do you know, I guess they did make a book out of it.
