I used that when called upon to do an "impromptu" speech, in my college Speech class. After I introduced myself, I announced the subject, The next world war conflict, by raising my voice and yelling "BOOM", asked for questions, to a stunned audience, then sat down. Got an "A". In my next impromptu speech I announced we would have an exhibition of two sand fleas f------. clapped my hands together rapidly, then sat down. Got an "A". Never got called on again. Why don't u college guys try that.
i like things that go BOOM!
