From the Swallowing The Camel blog, a list of "The World's Weirdest/Stupidest Conspiracy Theories." Here are a few of my faves, in no particular order. The author of main proponent of each is listed beside the theory. From the post:
• Stephen King killed John Lennon. (Steve Lightfoot)Link (Thanks, Vann Hall!)
• WWII was staged. It never really happened. The Illuminati employed elaborate special effects, stage magic, and phony journalism to scare the world into pacifism. (Donald Holmes)
• The doomed Franklin Expedition was sent to the Arctic not only to find the Northwest Passage, but to secretly investigate UFO sightings that had been reported since the 1700s. The men were captured, experimented upon, and eaten by giant aliens. (Jeffrey Blair Latta)
• The 1939 War of the Worlds radio broadcoast was a psychological warfare study funded by C.D. Jackson on behalf of the Rockefeller Foundation, designed to find out how Americans would react to an enemy invasion. Funny... in a trailer for his mockumentary F is for Fake, Orson Welles did say the WoW broadcast had "secret sponsors". (Daniel Hopsicker)
• Aspartame, flouride, genetically modified foods, and vaccines are used specifically to keep us sick and open to suggestion, and/or as part of a secret depopulation plan designed by the world's elite.
