Danny Porter was confused. He'd been wandering between periods when Sarah, the sexiest and most stick up girl in school had come running up to him and started making a major play for him, right there in the hall. Then he'd felt her holding some kind of rock in her hand as she thrust it into his. Finally, she'd demanded that he wish some statue be able to function like a person.
"What?" Danny asked in bewilderment. He knew Sarah was using him to get something she wanted - that's what Sarah did, after all - but she was being even more evasive than usual. "Sarah, sometimes I wish you'd just tell me what the heck's going on."
There was a brief flash of light, and Danny felt compelled to glance away. When he looked back, Sarah was looking at him wide eyed, like she was about to do something she didn't really want to do, but had no choice in.
"Okay," she said, "The fact of the matter is, I'm not really Sarah at all - I'm Jon, trapped in Sarah's body. I used my wishing stone to accidentally turn myself into Karyn's bra, and then Karyn accidentally turned Sarah into her panties for a day after Sarah insulted her, then she accidentally turned herself into a statue, then Sarah found got hold of the rock and shrunk Karen down to a few inches high out of revenge, then she took away my ability to make wishes, but then she accidentally swapped herself into my bra-body and vice versa, so I need your help to make Karyn be able to move and speak so she can help me straighten out this mess!"
Sarah gasped in relief, terror and possible asphyxiation, and as she did, Danny pulled the rock from her grasp. "So - this is a magic wishing rock, right?"
"Uhhhh, actually it's n-n-n-n- it is."
"And you're not Sarah, you're just Jon in Sarah's body?"
"I'm S-S-S-S- Uh, yeah, that's right. And apparently," she said, looking morose, "after that last wish, I can't lie to you at all."
