"... you wanted me to possess the rock because you think I'm pretty."
Suddenly Jon felt a cool wind blow through him. Why was he so angry that Sarah had stolen his rock? Sarah was hot! Jon had always liked Sarah! Jon knew there was no better way to impress a good looking girl than to give her something as priceless as... say... a wishing stone?
Jon smiled. "Sarah, you can have the rock. Really. I think you could have some fun with that."
"Thanks JoN! I think I might have some fun right now. I wish Jon was ten years old."
Jon suddenly began to shrink. He lost all his muscle mass and he could feel the hair on his body grow thin.
"Sarah! I didn't give you that rock to do mean stuff!"
"Shut up Jon! Wait until you see what's next!"
