Dateline: 2023. The Earth is a dead planet, the nuclear holocaust exterminated 98% of all life. Their exists only in the faintest memory of the oldest survivors, the reasoning for creating a man mad apocalypse. They would tell this story to hyperactive children, who would moan and groan at being made to listen to fairytales.
"In the times before the fall, there existed two tribes, they covered the length and breadth of the Mother sphere, back when she gave fruit and berries to all, and no man went hungry. These tribes were called the Trousers and the Pants. They both wore the ancient garment of power, and once, a long time ago, the Mother sphere was united with the love of the ancient garment. However, one of the tribes, they who drank leaves and cow milk, demanded the ancient garment be called 'Trousers'. While the other tribe, those who ate cow between bread, and drank beverages which fizzed, and would often declare hostilities on other tribes, said 'Nay, by the sage of the diviner, it shall be called Pants'. The tribe who dressed in Green and the Maple tribe with the weird accents just sort of stayed out of the way. It was not long before their warriors went to war, firing metal shards at each other and screaming their battle cries "Tah-Lee-Ho!" and "Ah-Mer-i-Cuh Fu-kyeh!". Soon they started chucking spears at one another, but these were spears that made a big boom! And soon, they coated the earth with green, and we survived only by living in a hole filled with what they called 'Twinkies' as they guard against the green for years. And that, little ones, is how we are living here today"
"Boring" Chirped the little brats, and went off.
Basically, the play would be just one guy telling the story, with occasional interuptions. It would be a bit like that Samuel Beckett play I can't remember the name of, just one guy talking. Very easy to put on!
