19. "Jody gave one of his big heh heh laughs and stood back." (pg. 41)

This sentence suggests that this is Jody's regular way of laughing. To me it sounds like it is either forced or nervous. It makes it seem like Jody is just laughing to get people to like him. He wants them to think he has a sense of humor as well as respecting him for his accomplishments.
