The Devil's advocate
I use the phrase sloppily, as a kind of joke. I'll say things like 'I'm working for the devil", and mention the "dark overlords" at places i've worked. But I don't seriously believe that Satan worshippers run the world. That would be really crazy. Well, I think McCain meant it the same way I do, but, evidently, some folks take it seriously. I guess they've never heard of Freemasons,or their symbols, huh?
