Here's a short story:

Billy was like a king on the school yard. A king without a queen. He was the biggest kid in our grade, so he made all the rules during recess. He was a big bully. He told kids what to do, what to play, what to sing, and called them names like "Dork". He always had a smile on his face as he sat on the bench next to the big tree and watched his "kingdom". All of the other kids were scared of him. Even I was scared of him. He was mean and he could beat you up if you made him angry. Last week, a very, very stupid kid chose not to listen to Billy. Billy beat him up and Mr.Stupid Kid told the grownups that he tripped. No one would dare get Billy in trouble. Billy was mean, but he kept the school yard from getting too crazy. Well I had enough it. Billy had been picking on us for too long and we had to stop him. I grabbed some fishing line from home and brought it to school the next day. Before recess, I tied a long piece of fishing line around the tree by Billy's bench and tied the other end to a big rock. Then I went inside for class. When it was recess, Billy sat on his bench and started yelling at people. This was it. I called out, "Hey you big dummy! You're not so tough". Billy's face turned red with anger and he started marching my way. Billy marched and then tripped over the fishing line. Billy was lying face down and he seemed to be crying. Everyone cheered. The king was down. (End of story)
