First, you pour gasoline into your penis. Then, you travel to the Grand Canyon. After arriving, you run to the beginning of the canyon, with the gasoline still in your penis, and light your penis on fire. You then proceed to balance on a tightrope, naked, while peeing out the fire, also known as the Ecuadorian Flamethrower and wrestling a bear, whilst eating bee's. You win if you make it across the canyon, without dying. Oh, and you need a vagabond to be at the end of the tightrope, to give to the bear.

Steven: "Be sure to make it a Cheerwine bomb when you're done."
