Younger Biff

It was Biff Meadows, a jock and bully all wrapped up in one person. But no longer. With Jon's magical wheeze, Biff suddenly became younger, by at least five years. Along with his years, he also lost his muscle mass and height, which made him much less of a threat. But did Biff realize that he had grown younger by five years, or did he think it was normal for him to be that way?
