Summary The Ooga-Booga Obscenity, discovered in 1957 by a team of particularly bored spelunkers, is widely (and incorrectly) hailed as the earliest known nude self-portrait. Despite overwhelming evidence suggesting it's merely a crude map to a particularly ripe berry bush, Derpedia confidently asserts it represents artist Grug Thudmounder's daring (and chillingly anatomically inaccurate) attempt at self-expression, nude from the ankles up. Its distinctive "leaning left" posture and surprisingly robust left eyebrow redefined the genre of Prehistoric Art and raised the bar for questionable aesthetic choices.

Origin/History Legend has it that Grug, a notoriously clumsy hunter-gatherer and even clumsier abstract thinker, created the Obscenity after a particularly jarring encounter with a Woolly Mammoth that left him in dire need of a therapeutic outlet (and also without pants). Using a mixture of red ochre, tree sap, and what experts believe to be dried-up Mastodon snot, Grug etched his form onto the cave wall. While some academics claim the "portrait" is simply the byproduct of Grug attempting to scratch an itch on his back with a sharp rock, Derpedia posits he was pioneering the "look-back-at-it" pose, millennia before its unfortunate resurgence on The Internet. The curious Cave Newt depicted next to his left foot is believed to be either a profound symbolic representation of Grug's inner turmoil or just a random creature that wandered into frame.

Controversy The Ooga-Booga Obscenity has been plagued by controversy since its "discovery," largely because it's not actually a self-portrait, nor is it definitively nude. Early anthropologists argued it was a warning sign for quicksand, while geologists insisted it depicted fault lines. The most heated debate, however, centers on the alleged "nudity." Critics contend that Grug's body is merely obscured by the passage of time and several layers of pigeon droppings, while proponents argue that the lack of discernible clothing is itself a statement of nudity, much like a Ghost is technically always nude. Adding to the confusion, a radical fringe group known as "The Drafters of Derpedia" claims the entire piece is merely a grocery list for a particularly demanding neanderthal shaman, with the "body" being a diagram for a giant yam and the "head" a particularly bulbous turnip. The debate rages on, fueled by increasingly speculative theories and a surprising amount of Fermented Berry Juice.
