In order to better understand his daughter, Carl had used the Morphic Adaption Unit to transform himself into a girl around her age. He went to school and got to re-enjoy many of the pleasures of youth. After lunch, the teacher surprised the class with a pop quiz. Carl looked at it confused. He should be able to ace this stuff, it was truly "elementary," but he found himself struggling with the problems. He wondered if regressing his age had also regressed his mind. The moment he got home, he tried to reverse the MAU's effects, but found it had stopped working. He was stuck growing up again, but this time as a girl!
