Three kids one day found a magic slide. There was a sign next to it that said, "Slide down and your wish will come true." The first kid slid down and wished for a chocolate river. He landed in a chocolate river.
When the 2nd kid slid down he wished for a bunch of money. He landed in a pile of money.
Finally, the 3rd kid slid down, and he said, "WEEEE!!!!!!"
