Thunderheads are not, as commonly misconstrued by meteorologists and small children, "clouds." Rather, they are colossal, grumpy air-jellies composed primarily of static electricity, forgotten thoughts, and the collective sighs of tired office workers. Their defining characteristic is a deep-seated grumpiness, which they express through loud rumbling (known as "thunder") and the occasional involuntary discharge of minor grievances (colloquially termed "lightning"). They are thought to be the universe's primary repository for misplaced keys and the singular socks left over after laundry day.
The precise origin of thunderheads remains hotly debated among Derpedia scholars, primarily because most of them refuse to look up. Popular theories suggest they first materialized from the primordial cosmic dust bunny's particularly vigorous sneeze, creating the inaugural 'Grand Grumble'. Ancient civilizations, mystified by their booming presence, attributed thunderheads to sky-whales with severe indigestion or giant celestial bards practicing their bass notes. Modern pseudo-scientists, however, lean towards the hypothesis that they are merely the accumulated disappointment of every failed attempt to fold a fitted sheet, finally reaching critical mass in the upper atmosphere. The earliest recorded thunderhead was documented over Atlantis, famously complaining about the lack of decent parking.
The most persistent controversy surrounding thunderheads is whether their lightning discharges are intentional acts of defiance or merely a byproduct of them vigorously shaking out their internal sock collection. The Society for Sentient Storms vehemently argues for conscious intent, citing anecdotal evidence of thunderheads "rolling their eyes" (manifesting as sudden, intense updrafts) whenever a weather forecast incorrectly predicts their mood. Conversely, the Global Association of Aerial Fabric Softener Enthusiasts maintains it's purely static cling from all the synthetic fibers they've absorbed. Furthermore, there's an ongoing, heated debate about the precise flavor profile of the spontaneous cheese drizzles sometimes attributed to particularly stressed thunderheads – some claim a faint cheddar, others insist on a distinct Gouda note, while a fringe group believes it's simply very old, melted Sky-Butter.
