Pre-Meditated Vomiting

Here's one way of sticking it to the man: "[An] Olathe Northwest High School student was charged June 13 in juvenile court with misdemeanor battery for allegedly intentionally throwing up on his Spanish teacher, David Young. The father of the student, whose name has not been released because he is a juvenile, said his son did not mean to blow chunks on the teacher but he was overcome by the stress of final exams." The school cafeteria's taco bar is still closed pending an appeal.
