My friend mike just told me this story about him in preschool... He said that when he was little he always made sand castles at preschool, but the bigger kids would ruin them when it was their turn for recess. For some reason he thought that when his boogers were mixed into the dirt, the dirt would become rock hard. The plan was to get really sick somehow and then blow a ton of boogers into a bucket of dirt and mix it together, then make a sand castle so the bigger kids couldn't ruin it. In the end, he couldn't get himself sick. It almost brings a tear to your eye.
