Tweaking

Jon knew that if he tried to do too much to change his wish, he would probably wind up turning his dad into a woman or something. Besides, it wasn't so bad having a mom like Art, just maybe not quite SO much like Art. After careful consideration, Jon wished, "I wish that Mom looked like she did before I made that last wish and not like Art." Glancing at a family picture, Jon saw that the wish was successful, and his mom at least looked like his mom again.
