Mr. Jones, the elementary school principal, made it a practice to visit the classes from time to time.
One day a week, he walked into Miss Smith's 4th grade class, where the children were studying American History.
Mr. Jones asked the class how many states they could name. They came up with about 40 names.
He jokingly told them that in his day students knew the names of all the states.
From the back of the room Little Johnny yelled, "Yes, but in those days there were only 13!"
