The Treaty of Jiggerstick

Once, when the world was very young, there was a great feud between the Bears and the Sharks. The war went on for years, decades, millenea. One ay, when things were at their grimmest; a young boy known only as Jiggerstick appeared at the horizon.
"Do not fight!" the boy cried. "There are much more important things to be thought of!"
"Like what?" one of the bears gruffly asked.
"Like girls," the boy replied. "Girls on trampolines."
"Girls on trampolines?!" a shark retorted. "What is so great about girls on trampolines?!"
The boy chuckled and handed the shark a videocasette. "You shall see," he said. "In the meantime, I do declare that the Bears and Sharks should live in harmony!"
The two animals looked at each other, and nodded. Harmony, girls, and trampolines didn't sound like such a bad idea.
That night, there was a massive party. The Bears and Sharks were united, and there were many girls on trampolines. A treaty was signed, binding the Bears and Sharks: The Treaty of Jiggerstick, named after the mysterious boy who showed the Bears and the Sharks the wonders of humans of the female gender bouncing on pieces of canvas stretched tightly over a metal frame with springs.
