Undeniable Fact: A Loose Cannon

You may be surprised to learn that the cannon and cannonball were invented independently by two different people, both of whom were seen as insane during their time. The inventions were commonly assumed to be useless for many years, until King Charles III of Spain had the idea of using the two in conjunction with one another. Although he is commonly credited with the invention of the modern cannon, Charles III merely put together two pieces which had existed long before he was born. But credit where credit's due: he did invent the ramrod.
