Come on, kids. It's fun. Here's mine:
"In order to understand you need to realize that everything is controlled by a conservative cabal called PNAC made up of billionaires with help from Fox News anchors. The conspiracy first started during the colonization of America in the secret moon base. They have been responsible for many events throughout history, including the Holocaust. Today, members of the conspiracy are everywhere. They can be identified by chewing gum. They want to murder Iran and imprison resisters in Crawford, Texas using buses. In order to prepare for this, we all must protest. Since the media is controlled by Ralph Nader we should get our information from Bill O'Reilly."
