There’s a plethora of good Chuck Norris jokes, and not only the British and Americans like them, for instance: As a child Chuck Norris built sandcastles. Today, we know them as pyramids. Chuck Norris actually died 10 years ago. But death hasn’t had the courage to tell him about it yet. Chuck Norris is so fast, he can run around the earth and kick himself in his back. But, of course, he would see this attack coming ... Chuck Norris is the only man who can REALLY kill time. Chuck Norris has already been on Mars. That’s the reason why they cannot find any life-form there.

'Cause Chuck is the only man who can divide by zero! )))

Chuck Norris(查克·诺里斯，1940年3月10日-)，空手道世界冠军，美国电影演员，动作片演员，因1972年拍摄电影《猛龙过江》在古罗马竞技场与李小龙搏击声名大噪，且被誉为世界电影功夫片不朽经典镜头。2005年因在肥皂剧中夸张的演出成为风靡一时的网络现象，网络上出现无数版本的“诺里斯事实”，于是他成了全球恶搞的代表。 具体情况你可以参考：http://baike.baidu.com/view/547805.htm
