Dr. Eric Stutman turned to Dr. Keith Wooley and said "was that part on the horneyness really necessary. remember we're legitamate researchers not horney teens."
Keith sighed. "you're right, I guess seeing those bare breasts got my mind in the wrong place."
Eric took the stone and said "I wish Karyn would keep mowing until she either notices her breast growth or the breast growth makes it impossible for her to mow, and that the mower will be full of gas until either of those events happen."
"Wait, how is THAT supposed to be scientific". keith said, a bit annoyed that eric took the stone to make a seemingly frivolous wish.
"Very easy", said Eric. "When we first made Jon think he was his own mother and Karyn thing she was Jon's dad they noticed their clothes fit a bit wrong, yet did not notice their bodies did not match who they are. I am testing how far her breasts have to grow until she notices, assuming she notices at all."
"But if she DOESN'T notice her breasts will either be too big for her to reach past them to touch the mower, or if she tries pushing it in other ways, too big for her to move." Said keith.
"I know" Eric replied smiling brightly. "Isn't it wonderful!"
