"I wish that Joan would be the good looking 26 year old school principal at this school until four o'clock today. I wish that Joan would recognize the changes to reality, would know that I made the wish that made her our principal, would have the knowledge to perform her job duties while she is a principal and would know the exact wording of my wish." The stone grew warm in Nicoles hand and she was forced to close her eyes as her wish took effect.
Nicole opened her eyes and looked around to see that Joan was no longer in the locker room.
"It worked," thought Nicole, "Awesome. I think I might pay a little visit to the principals office once class is over. Having my best friend be the school principal is bound to have more than a few perks."
