A kid no one has ever seen before is walking the playground, bringing bad luck and peanut butter wherever he goes. He finally settles on our gang, and they begin having the worst luck of their lives, balls and bats being damaged, injuries, and other indescribable odd fates. The gang thinks about what had made their luck so bad, then they figure it out. The Peanut Butter Kid is a jinx!
They then try to ditch the Peanut Butter Kid, sending him around the playground, the state, and the world. Eventually they confront him, and he then walks away sadly. When the bad luck continues, however, they realize that it wasn't the Peanut Butter Kid's fault, that they were mean to him for nothing, and mainly, that bad luck cannot be blamed on any one thing. When they try and reconcile with the Peanut Butter Kid, he has met a new group of friends to hang out with. However, as both a sign of forgiveness and to remember him by, the Peanut Butter Kid gives them the remains of his sandwich. They then go back to their old ways, and meet a new girl, who always eats ice cream, they then run for their lives before she can become attached so as not to make the same mistake again.
