On the matter of chalk erasers

When some one misbehaved in class or did not pay attention Flt Lt Tucker would, with great accuracy, hurl a chalk dust loaded eraser hitting the student 100% of the time. The student would then pick up the eraser and return it to Tucker saying, “Excuse me sir I believed you dropped this…” the student would then go back to his or her seat after being thanked. If Tucker thought the situation warranted he would hit the student in the back with the eraser again and the student would bring the eraser back. This process would continue until Tucker was satisfied he had made his point. Parents could gage how well their children were behaving in class by the chalk marks left on the clothing when they got home.
