The Electric Kool-Aid Acid Test is a great book that explains a lot of it. When Ken Kesey and his buds, the Merry Pranksters, went into San Francisco, they painted their bus dayglo colors and dressed up like clowns and stuff and stood on the top of the bus waving at people like it was a parade. Part of the purpose was to freak people out. They like to screw with your mind and keep you off balance. This is one of the reasons they hate Limbaugh. Limbaugh gets them, and screws with their minds.
