Now, let's see, thought Jon. Biff became a girl because of two wishes. The first wish was that he and his friends become cheerleaders now, and the second was Biff wishing that he and his friends could become normal.
It wasn't hard to reverse. In the first wish, he used the word "now". So the wish didn't have to continue. And the second wish was just the stone interpreting a wish in the wrong way. He could tell the stone to do it the right way. "I wish that 'cheerleaders now' in the wish I used on Biff meant that he would become a cheerleader at that point in time, but that he wouldn't continue and in fact would change back right now. And I wish that 'normal' in his wish meant exactly what he meant it to mean."
But Jon had to apologize to Biff. Maybe that could even get Biff to like him... How about wishing for Biff to be attracted to him, or to be his boyfriend already? Jon considered it, but decided it wouldn't be right. He had to leave Biff free to accept or reject him according to his own will.
Oh, heck. "I wish Biff were here."
The boy appeared out of thin air. He looked around and yelled. "What's going on here?"
"I brought you here" said Jon. "I wanted to, er...." Jon blushed. "I wanted to say I'm sorry!"
"You drugged me, you putz! I ought to teach you a lesson...."
He must have thought he was hallucinating. "I wish Biff knew about the stone and remembered being changed to a girl."
"I..." Biff stopped and a second later started yelling at Jon again. "You turned me into a girl! I was a cheerleader! How dare you..." He raised a fist but suddenly said "Just be glad I'm in a good mood today" as his father's wish for him not to be violent to Jon took effect.
"Biff, I had to apologize! Please accept it! Don't you realize I love you? I want you to hold me and kiss me and... and..."
"You homo! You're going to die for even suggesting that!" Biff looked at Jon, and once again for some reason didn't lay a finger on him. "I'll give you a break, but if you try that again..."
"I'm a guy! I can't help that, Biff."
"Sorry, I only go for girls. With pussies, you know."
"Biff, please! Fo you I'll do anything! I wish I had a pussy." The stone might have easily misinterpreted that and given him a cat, but it didn't. He felt strange as his erection for Biff turned inside out and left him with female organs.
Biff gaped. He knew the rock was a wishing stone, so he knew what Jon had just done. "No! You're a guy! No matter what you do to youself, I'm not going to go out with anything except a woman, and I mean someone who's really a woman! I ought to tear you in pieces for that..." But he didn't.
"Biff" said Jon while touching the stone, "I wish you weren't uptight about whether people are boys or girls and that you'd be attracted to people like me."
That wish still fit with Biff's father's wish. Jon, by wishing that, didn't deny Biff his free will. Biff was attracted to people like Jon, but he didn't have to be attracted to Jon in particular. And Biff didn't have to try to get in bed with everything he was attracted to, either; if he did so, that was purely his own choice.
But it so happens that Biff made those choices anyway. "All right, baby" he said, and embraced Jon. "You're such a hottie. Come here and give me a kiss..." Jon was getting what he wanted now, but Biff could very well end up treating Jon like he treated his previous girlfriends....
