There was once a wrestling master who was versed in 360 skills.

he came to like one of his pupils, to whom he taught 359 skills over

a period of time. As months went by the young man became so proficient

in the art that he defeated every other player. He was so proud that one day

he boasted before the king that he could readily beat his master. The king

became upset at his irreverence and ordered an immediate match. At the

gong the youth pushed forward with a yell, only to be confronted with the

unfamiliar 360th technique. The master seized his former pupil and flung

him to the ground. When the king asked the master how he was able to win,

the master confessed that he had reserved a secret technique for himself for

such a contingency.
