Apparently, Casey had been picked on for years by little runts like this kid, who shall forever more be known as The Rat. Casey finally had enough when The Rat and his stooges tried to record their bullying sessions.
If the Dramatica article is to be believed, Casey was suspended for four days. The Rat received a twenty-two day suspension, a dislocated knee, and a lifetime's supply of humiliation. The Rat's parents also seem to be suing every sentient creature that was within a five-mile radius of the smackdown.
