The voice from the rock interrupted John's train of thought. The strange voice that sounded like it came from a B-movie Indian Shaman said,"You can, however, alter the effects of his wishes with the stone after he has made a wish. Joseph's wishes still draw from the spring of magic that lies within this stone so his three wishes are the same entities that the wishes from the stone are."
"Well at least I can still use my stone to hopefully correct his wishes. I'm starting to regret that I wished that he would be oblivious to his wishes being granted. Maybe if I hadn't done that I could have just talked him through his wishmaking, but Noooo, I just had to keep this stone a secret from him. Oh well, I guess I have to do this the hard way."
"So what would your three wishes be," asked John, "I mean, what would you wish for if you could have any kind of car or gaming console?" John looked at Joseph hoping that he would make it easy for him.
