As most young, weak and smart kids are, Ken was picked on constantly by the bullies in school. They stole his lunch, they beat him up and just downright made his life miserable. It took him a couple of weeks to find a way to get back at these bullies and when he found out what would get them back, he went all out.
He was on the bus where he normally got his lunch stolen when he brought out a bottle that had what looked like small brown balls in it. He then, making sure no one was looking, secretly took from his pocket some milk duds and started popping them in his mouth as obvious to the rest of the kids as possible making yum yum noises.
