I'm not sure if that attribution is accurate. Nick has pointed out to me that he knows the same quote attributed to someone else, so this may be a case of internet misattribution (I picked up that quote from somewhere online, way back when -- no idea if the source was reliable, y'know, being the internet and everything).
