I've started reading a popular book on punctuation and the abysmal state of its use, given to me by a friend of mine, "Eats, Shoots and Leaves" by Lynne Truss. Encouraged by her book, people sent her examples of idiotic punctuation. One--sent in by a Shakespearian actor--was a sign that said, "Children Drive Slowly." The resulting brouhaha prompted the town to revise the sign.
It now reads, "Children, Drive Slowly."
