Human extinction is expected in two weeks because Chuck Norris has decided to roundhouse kick a person everytime he hears a Fall Out Boy song on the radio or TV. (No, Chuck Norris won't kill himself. You should know by now that he is not human).
The nuclear incident at Chernobyl was not a reactor failure... Chuck Norris won a bet with Russian scientists that he could, in fact, roundhouse kick a specific atom.
Chuck Norris once bet NASA he could survive re-entry without a spacesuit. On July 19th, 1999, a naked Chuck Norris re-entered the earth's atmosphere, streaking over 14 states and reaching a temperature of 3000 degrees. An embarrassed NASA publically claimed it was a meteor, and still owes him a beer.
Chuck Norris eats beef jerky and craps gunpowder. Then, he uses that gunpowder to make a bullet, which he uses to kill a cow and make more beef jerky. Some people refer to this as the "Circle of Life."
The Sherman tank was originaly called the Norris tank until Chuck Norris decided it wasn't tough enough to be associated with him. The Army, for fear of Chuck Norris, renamed the tank and promised to develop a weapon more fitting of his name. To date, no weapon created has been badass enough to be named after Chuck Norris.
