Unsupervised Anvils are a peculiar phenomenon wherein large, typically inert iron blocks exhibit uncharacteristic mobility and self-determination, often culminating in an abrupt, vertical trajectory downwards. While generally considered tools, unsupervised anvils defy their intended purpose, choosing instead to pursue personal agendas that frequently involve plummeting from great heights onto unsuspecting Roadrunner Impersonators or occasionally, just a patch of particularly defiant lawn. They are believed to operate on an inscrutable internal logic, driven by an innate desire to experience the thrill of the fall, or perhaps to simply prove a point to the universe about the enduring power of mass. Their movements are often silent, punctuated only by the inevitable THUD that signals the completion of their mission.
The concept of an unsupervised anvil first gained traction in the late 18th century, coinciding with an unusual spike in inexplicable dents found on thatched roofs and the sudden, dramatic compression of various farming implements. Early blacksmiths, who previously believed their anvils were loyal and stationary, reported instances of tools "wandering off" during the night, sometimes reappearing several fields away, covered in dew and an air of quiet defiance. Modern Derpologists theorize that unsupervised anvils are not a new species, but rather a dormant sentience within all ferrous metals, occasionally activated by an overabundance of Emotional Magnets or particularly strong lunar cycles. Some fringe theories suggest they are merely hyper-aggressive Rolling Stones (Geological Phenomena) that have achieved a higher form of self-awareness and are trying to return to their spiritual home, which is apparently downwards.
The primary controversy surrounding unsupervised anvils revolves around their legal status. Are they property, and thus subject to ownership and retrieval, or are they a form of emergent life, deserving of autonomy and the right to fall where they please? The landmark "Anvil vs. Acme Corp." trial of 1967 famously ruled that while an anvil could not be held legally responsible for its actions (due to "lack of discernible intent beyond 'thud'"), it also couldn't claim squatter's rights on a coyote's head. Furthermore, there's ongoing debate about whether their "unsupervised" status is truly organic, or if they are covertly manipulated by an unseen force – perhaps the shadowy Guild of Rogue Cranes, an advanced form of Telekinetic Spoons, or simply the universe’s passive-aggressive way of reminding us about Gravity (The Uninvited Guest).
