A.A. Milne, Autobiography. New York: E.P. Dutton, 1939, pp. 52-53—flag waving / anon
The only occasion on which I spoke in the Debating Society was at what was called an “Impromptu Debate.” The names of the members were put into one hat, the subjects for speech into another. In an agony of nervousness I waited for my name to be called. It came at last, “Milne Three.” Milne III tottered up and drew his fate; not that it mattered, for one subject was as fatal to him as another. He tottered back to his desk and opened the paper. The subject on which he had to speak was “Gymnastics.”
I stood there dumbly. I could think of nothing. The boy next to me, misapprehending the meaning of the word “impromptu,” whispered to me: “Gymnastics strengthens the muscles.” I swallowed and said, “Gymnasthicth thtrengthenth the muthelth.” Then I sat down. This is the shortest speech I have ever made, and possibly, for that reason, the best.
