People who believe in every conspiracy theory under the sun are called the Tin Foil Hat Brigade, at least by me. That is because it is believed that "Tin Foil" (Which is actually ALuminum) will block the radio waves the government (or aliens) uses to fry our brains. They make references to this in the movie Signs.
It's newest member is a weatherman who recently quit is TV job in Idaho Falls so that he can promote his theory that terrorists caused Hurricane Katrina.
Well, now some students at MIT have proven that the hats just don't work. In fact, they amplify the radio waves, making them more powerful.
I love Nerds.
