Since Jeff Wysaski of Obvious Plant is busy leaving free dating advice in floral departments, as well as leaving hilarious store tips all over grocery stores, one other person decided to go a different route and leave fake trivia books in numerous book stores.

Imgur user JWaldman explains that this little project started off as a surprise wedding gift for a friend, which was pretty much a running list of fake trivia they had made up. And it took a life of its own when he noticed they could order a bunch of these books and leave them for folks at bookstores.

JWaldman also mentions that the books look legit, as they have a copyright page, ISBN number and publisher info. Check out the inside of these books below:
