One of the most rewarding aspects of mastering a new skill is sharing that knowledge with others. While some facts are strange and beautiful, while others are completely worthless. There is a whole category of trivia that is so fantastic that you can't help but ask everyone you encounter, 'Did you know this?!' These are the facts that will amaze you and your friends, ranging from why grapes catch fire in the microwave to how long it takes the typical animal to urinate.
