Charlie was walking through a small street in Tokyo and noticed a sign that read, "Short sword tournament final." He didn't know what a short sword was, so he walked in to take a look. It was just at the end of the medal ceremony. He proceeded to ask the bronze medal winner what a short sword is and how the tournament is done. The bronze medal winner showed him the sword. It was indeed a fine sword -- about a foot long but sharp as a razor. Charlie asked how the man won the bronze medal.

The man said, "See fly buzzing?"

"Yes," replied Charlie.

The bronze medallist went, "Hiii... Yeeaaah!"

Lo and behold, the fly was cut in half right down the center.

"Wow," thought Charlie. "I wonder what the silver medallist can do."

So he went to ask what the silver medallist had done.

The silver medallist said, "See fly buzzing?"

"Yes," said Charlie.

The silver medallist went, "Hiiii...Yeeeah" twice.

Lo and behold, the fly was cut into four exact quarters.

"Fantastic!" thought Charlie, who proceeded to find out what the gold medallist had done.

The gold medallist said, "See fly buzzing?"

"Yep," said Charlie.

The gold medallist just gave a flick with his wrist, and the fly went buzzz and flew away.

"Ha! missed, eh?" said Charlie.

The gold medallist said, "Ah, no! Not miss. Fly can no longer have children!"
