   A 10-year-old boy decided to learn judo though he had lost his left arm in a car accident. The boy was doing well, so he couldn't understand why, after three months of training, the master had taught him only one move.
   “ Master,” the boy finally asked, “shouldn't I be learning more moves?"“ This is the only move you know, but this is the only move you'll ever need to know,” the teacher answered.
   Several months later, the teacher took the boy to his first competition. Surprising himself, the boy easily won his first two matches. The third match proved to be more difficult, but after some time, his opponent (对手) became impatient and charged; the boy skillfully used his one move to win the match. Still amazed by his success, the boy was now in the final.
  This time, his opponent was bigger, stronger, and more experienced. Soon after the match started, the boy seemed to lose. Thinking that the boy might get hurt, the judge called a time-out. He was going to stop the match when the teacher appeared. “ No,” the teacher said, “Let him continue.” A short time after the match carried on, his opponent made a careless mistake. At once, the boy used his move to pin (压住) him. The boy won the match and the competition.
  On the way home, the boy asked the teacher what was really in his mind. " Why could I win the competition with only one move?" The teacher answered. "First, you've mastered one of the most difficult throws in judo. Second, your opponent can only attack your left arm to win you.”

官封弼马心何足  名注齐天意未宁

       ①太白金星,领着美猴王,到于灵霄殿外。不等宣诏,直至御前,朝上礼拜。悟空挺身在旁,且不朝礼,但侧耳以听金星启奏。金星奏道:“臣领圣旨,已宣妖仙到了。”玉帝垂帘问曰:“那个是妖仙?”悟空却才躬身答应道:“老孙便是。”仙卿们都大惊失色道:“这个野猴!怎么不拜伏参见,辄敢这等答应道‘老孙便是’却该死了,该死了!”玉帝传旨道:“那孙悟空乃下界妖仙,初得人身,不知朝礼,且姑恕罪。”众仙卿叫声:“谢恩!”猴王却才朝上唱个大喏。玉帝宣文选武选仙卿,看那处少甚官职,着孙悟空去除授。旁边转过武曲星君,启奏道:“天宫里各宫各殿,各方各处,都不少官,只是御马监缺个正堂管事。”玉帝传旨道:“就除他做个‘弼马温’罢。”众臣叫谢恩,他也只朝上唱个大喏。玉帝又差木德星官送他去御马监到任。

       ……

       ②不觉的半月有余。一朝闲暇,众监官都安排酒席,一则与他接风,一则与他贺喜。正在欢饮之间,猴王忽停杯问曰:“我这‘弼马温’是个什么官衔?”众曰:“官名就是此了。”又问:“此官是个几品?”众道:“没有品从。”猴王道:“没品,想是大之极也。”众道:“不大不大,只唤做‘未入流’。”猴王道:“怎么叫做‘未入流’?”众道:“末等。这样官儿,最低最小,只可与他看马。似堂尊到任之后,这等殷勤,喂得马肥,只落得道声‘好’字;如稍有些尫羸,还要见责;再十分伤损,还要罚赎问罪。”猴王闻此,不觉心头火起,咬牙大怒道:“这般藐视老孙!老孙在那花果山,称王称祖,怎么哄我来替他养马?养马者,乃后生小辈下贱之役,岂是待我的?不做他,不做他!我将去也!”忽喇的一声,把公案推倒,耳中取出宝贝,幌一幌,碗来粗细,一路解数,直打出御马监,径至南天门。众天丁知他受了仙箓,乃是个弼马温,不敢阻当,让他打出天门去了。

       ③须臾,按落云头,回至花果山上,只见那四健将与各洞妖王,在那里操演兵卒。这猴王厉声高叫道“小的们,老孙来了!”一群猴都来叩头,迎接进洞天深处,请猴王高登宝位,一壁厢办酒接风,都道:“恭喜大王,上界去十数年,想必得意荣归也?”猴王道:“我才半月有余,那里有十数年?”众猴道:“大王,你在天上,不觉时辰。天上一日,就是下界一年哩。请问大王,官居何职?”猴王摇手道:“不好说,不好说!活活的羞杀人!那玉帝不会用人,他见老孙这般模样,封我做个什么‘弼马温’,原来是与他养马,未入流品之类。我初到任时不知,只在御马监中顽耍。及今日问我同寮,始知是这等卑贱。老孙心中大恼,推倒席面,不受官衔,因此走下来了。”众猴道:“来得好,来得好!大王在这福地洞天之处为王,多少尊重快乐,怎么肯去与他做马夫?”教:“小的们!快办酒来,与大王释闷。”

       ④正饮酒欢会间,有人来报道:“大王,门外有两个独角鬼王,要见大王。”猴王道:“教他进来。”那鬼王整衣跑入洞中,倒身下拜。美猴王问他:“你见我何干?”鬼王道:“久闻大王招贤,无由得见;今见大王授了天箓,得意荣归,特献赭黄袍一件,与大王称庆。肯不弃鄙贱,收纳小人,亦得效犬马之劳。”猴王大喜,将赭黄袍穿起,众等欣然排班朝拜,即将鬼王封为前部总督先锋。鬼王谢恩毕,复启道:“大王在天许久,所授何职?”猴王道:“玉帝轻贤,封我做个什么‘弼马温’!”鬼王听言,又奏道:“大王有此神通,如何与他养马?就做个‘齐天大圣’,有何不可?”猴王闻说,欢喜不胜,连道几个“好!好!好!”教四健将:“就替我快置个旌旗,旗上写‘齐天大圣’四大字,立竿张挂。自此以后,只称我为齐天大圣,不许再称大王。亦可传与各洞妖王,一体知悉。”此不在话下。
