MURPHY'S LAW FOR TEACHERS Good students move away. New students come from schools that don't teach. The most dingy room in school is the faculty lounge. Unless it's your classroom. The less time you have to make copies, the more the machine will malfunction. Disaster occurs when you're being observed. The time you take to explain something is inversely proportional to the degree students remember it. *The problem student will be the son or daughter of a school board member.
