Chuck Norris facts were first seen on the Internet in early 2005. Conan O'Brien's Chuck Norris jokes on "Late Night with Conan O'Brien" have been seen as a cause for the fad. These "facts" are similar to "Tall tales" such as those of Paul Bunyan. Chuck Norris Facts started being used in the gaming community shortly after a Chuck Norris Fact generator was created for use with World of Warcraft in early 2006.
