Free your mind and your ass will follow
"Free your mind and your ass will follow" -- Funkadelic, 1971 ([full lyrics])
Actually, I think there's a probably a Virtuous cycle between freeing one's ass and one's mind. Still, this is a good place to start.
I seem to recall that the Onion published an article "Clinton to free mind, ass to follow" (complete with a map showing the military campaign to free the mind); they were referring to Bill, not George.
