Karyn goes for it.

Jon put such thoughts out of his mind for now. "Okay, Karyn. Come on in," he called through the door. "Let me see the rock, " said Karyn. "I think I know what to do about my body." Jon tossed her the rock. "What do you have in mind?" "I've thought about it, and I need to wish that my boobs were big, but not this big. Then I can wish that my hair is blonde because I dyed it with wash-out hair dye, and that it'll wear off in a week," she told him. "I think I'd like to make my body a little more balanced, though. I'm just top-heavy now, and that's the real problem. When I got home, I noticed that all of my clothes are custom made for these," she gestured at her chest. "That's expensive." "Sounds to me like a good idea," Jon replied. "Go for it!" Karyn held the rock. "I wish that my boobs were a C cup, which is still big for me, and that my body was in the proper proportions to suit them." Nothing. "Let me try again. I wish," said Karyn, "that my hair was blonde because I dyed it with temporary dye that will wash out in about a week." Nothing again. "Crap! Well, I'm out of ideas." Karyn tossed the rock back to Jon. "Your turn."
