One of the books from the "Trivia Champion" Humble Bundle. And yes, it belongs to a "Trivia Champion" bundle.
The whole book consists on small stories about random objects: The smiley face, the revolver, the hydrant, the wipper, all consist in a small story behind it or some anecdote, like a campus on war due a water gun.
The stories are small and funny.
The only problem I had (and, again, personal problem) is that it is too American-centric. I mean, the whole war on a water gun mentions an American university; Dr Pepper is mostly unknown in Brazil; 90% of the people mentioned are American -- and, by the way, the little anecdote about the water gun has absolutely no relation to the creation of the product.
