You and I are both old enough to remember those words: "Fight, fight!!" Two boys, junior or senior high, full of spit and spite, decide to take it outside and settle it. The whole student body would turn out. Eventually the gym teacher would come and break it up (why was it always the gym teacher?). No classroom activity could do that, you could gather 200 to 300 kids with just those words.
And that is exactly what the BT boys just did. I wonder if any girls were around to watch?
