The 1972 Miami Dolphins lost one game, it was an exhibition game vs. Chuck Norris and three seven year old girls. Chuck Norris won with a roundhouse-kick to the face in overtime.
Chuck Norris Facts were originally seen on IRC, and on websites like the Something Awful forums, in early 2005. Conan O'Brien's Chuck Norris jokes on Late Night with Conan O'Brien (which generally center on Walker: Texas Ranger) have been seen as an inspiration for the fad. Chuck Norris Facts followed "facts" based on actors Vin Diesel and Bob Saget, and spawned similar "facts" about fictional character Jack Bauer from the television series 24, Mr. T, and other personages. The exaggerated style of these facts is similar to a recurring Saturday Night Live sketch called Bill Brasky. These are similar to "Tall tales" such as those of Paul Bunyan.
