"Give me the rock," asked Karyn.
Jon handed it over. "I don't know what you have in mind, but it can't be worse than what I'm doing."
"It's simple," said Karyn. "I wish that me and Jon looked exactly like human beings, so nobody can tell us apart from human by the way we look or feel or act unless they open us up or X-Ray us or something."
A second later, Karyn looked like herself again. And Jon was a female version of himself--which certainly looked more like Karyn than a male version of himself, so that wish was still going. She handed Jon back the rock, satisfied.
"We're back!" exclaimed Jon. "Only I'm a girl now."

Jon said "Well, I think I have a strange feeling on my forehead. Sort of itching." She pressed her fingers on it in a way that somehow she was familiar with, and a panel slid up in her forehead.
Karyn, too, found she knew how to handle robot equipment. "That's a programming port," she explained. "You plug in a new module and it reprograms you."
"Neat," said Jon. "I wish I had a module to test it with."
One appeared in her hands. And just as Jon had made a lot of bad decisions about wishes, she made a rather bad decision here. Programming yourself with a completely unknown module is not the smartest thing to do. But nevertheless, Jon plugged it in.

"Of course I'm okay," replied Jon.
"Do you feel strange?"
"Well, I do, in a way." Then Karyn picked up the module and turned it over to see the label. Jon's new programming was...."
