The utter lack of backstory on this sign makes it pretty counter-productive, considering all we can think about now is finding this kid and giving him every pencil we own, maybe even buying him some more. What the hell did he do? Attempt The Joker's infamous "magic trick"? Humiliate the teacher by solving an unsolvable math problem ala Good Will Hunting? Whatever it is, we shouldn't have a hard time finding him. He'll be the kid writing his English essay in sidewalk chalk.
