The first victim of Mikey's sticky notes was his brother Jon. Coming home from school, he found a Post-it stuck to the inside of the door of his room, and began to read it aloud. "I wish," he read, "that I would swap genitals with my counterpart of the opposite sex in our family, and that our new genitals would adjust to match our bodies' ages, and that everyone would remember reality as it was before the wish, and that we develop as if we had our original genitals."
Mikey had already made him forget the stone, so he just looked at it, shrugged, and said "What a bizarre prank." But when he tore up the note and tossed it away, he felt a strange sensation between his legs.
