Rushing to work, I was driving too fast and as a result was pulled over by the highway patrol. The state trooper noticed that my shirt had the name of a local high school on it. "I teach math there," I explained. The trooper smiled, and said, "Okay, here's a problem. A teacher is speeding down the highway at 16 m.p.h. over the limit. At $12 for every mile, plus $40 court costs, plus the rise in her insurance, what's her total cost?" I replied, "Taking that total, subtracting the low salary I receive, multiplying by the number of kids who hate math, then adding to that the fact that none of us would be any-where without teachers, I'd say zero." He handed me back my license. "Math was never my favorite subject," he admitted. "Please slow down."
