A lesson on efficiency

I remember my last year at school very well. There were three boys                          (NAME) William in my class. Miss Fisher, one of the teachers, called them all William, and we                          (NOT KNOW) which one she was talking to. One day, during a lesson on efficiency, she thundered, “William, put that gum you                          (CHEW) in the wastepaper bin at once!” All three of them started to rise, paused, then walked to the front of the class to dispose of their gum. The teacher beamed. “Three for one! Now that's efficiency.”
