Jimmy had it coming.
Math class is boring, we know. To spice things up, hide a spitball shooter under your Element Boys' Vertical T-Shirt and wait for your teacher to turn his back. The moment he's not looking, whip out your mucus cannon and barrage your best friend with a hail of slobbery paper wads. Before the teacher discovers what's happened, be sure to planet the straw and crumpled up paper ammunition on Jimmy the Hall Monitors's desk.
