In Chapter 15, Maniac’s fame is spreads all over the East End. Little kids are coming to him for help untying their shoe knots. Bigger kids meet him to play sports and to witness firsthand what an amazing athlete he is. “Hands” serves as Maniac’s resident “trash talker”, and he soon passes his abilities to Maniac, who begins to trash talk as well. When Maniac mistakenly trash talks Mrs. Beale, she slaps him for his impolite language. Maniac begins to sob and begs Mrs. Beale to forgive him.
