Good point there about your 5th grade teacher.... I had one just like her too. A real beast! We students would open our desktops and slip the nun's dangling rosary inside, then close the lid. When she walks off.... zing! beads go rolling on the floor! Now you know where the idea of having to stand in the corner with outstretched arms holding several textbooks came from!
