Favorite analogy all week, courtesy of the Guardian:
Bush is a bit like an unhinged iconoclast who has arbitrarily decided he doesn’t believe in cows, and loudly and repeatedly denies their existence until you get so annoyed you drive him to a farm and show him a cow, and he shakes his head and continues to insist there’s no such thing. At which point it moos indignantly, but he claims not to hear it, so in exasperation you drag him into the field and force him to touch the cow, and milk the cow, and ride around on the cow’s back. And, finally, he dismounts and says, “That was fun’n’all, but dagnammit, I still don’t believe in no cow.” And then he shoots it in the head regardless, just to be on the safe side. Just so it isn’t a threat.
