-The New World Order Conspiracy
-Swine Flu Vaccine has micro chips in them
-The Illuminati Conspiracy
-Reptile extraterrestrials running the US government
-No planes crashed into the WTC buildings on September 11, 2001
-Fluoride is put in our drinking water so that the government can dumb us down and destroy half of the population.
And other nonsense! There are tons of sites on the interwebs where many Looney conspiracy theorists dwell.
