The Apostrophe Murdered

The heartless abuse, misuse and sheer murder of the poor apostrophe continues. This was seen in a shop window in Dublin today. I was heading for the train, passed the window and stopped a few paces further on. Although I only saw the sign in my peripheral vision I just knew there was something wrong with it. I doubled back for a closer look and sure enough there it was. Another apostrophe killed stone dead. What are our schools doing at all?
