Granted, you woke up this morning and had a bowl of you favourite cereal for breakfast. You left the half empty bowl in the kitchen, where it was hit by a stray cosmic ray. A chain reaction was set up, causing the milk to evolve into a rudimentry life form, which crawled out into your basement. In there it breeds and evolves into a small society. Slowly, unknown to the world, it spreads through the sewer systems, until, many thousands of years from now, it develops nuclear weapons and destroys the world. Way to go - meathead
I wish my furniture would move itself to my new apartment.
