Suddenly I am remembering that British political satire show Spitting Image (the Genesis 'Land of Confusion' video.
They showed one episdoe on US network TV in the 80s and there was a secret cabal headquatered in Mt. Rushmore. (been 30 years since I say and I was young so I missed much of the political humor)
