Just in case were getting any ideas about getting back at any of your teachers during the school year who you didn't get along with, let the case of a student from Kansas make you reconsider.
A high school student from Kansas who vomited on his Spanish teacher has been convicted of battery and ordered to spend the next four months cleaning up after people who throw up in police cars. Now I don't know how many people throw up in police calls, but even if it were once a week, that would be about sixteen vomit cleanups, probably the grossest job ever. The student's lawyer said that the student threw up because he was nervous about an exam, but unfortunately the student had told some of his classmates that he did it on purpose. Probably not a good move...
