The World's Greatest SwordsmanAt an exhibition of the world's best swordsman, the third-place fencer took the stage. A fly was released, and with an arc of his sword he cut the fly in half. The crowd cheered. Then the second-place man sliced a fly into quarters. A hush fell in anticipation of the world's greatest swordsman.

His blade came down in a mighty arc - but the insect continued on its way! The crowd was aghast. The greatest swordsman had missed his target completely, yet he continued to smile.

"Why are you so happy?" someone yelled. "You missed!"

"Ah," replied the swordsman, "you weren't watching very carefully. They fly lives, yes - but he will never be a father."
