Link?
You need a link that proves someone famous has ever called someone else an idiot?
Or are you actually intending some subtle irony here and actually know from where the phrase came into popular use? (Hint: it's a fictional character on a well-known American cartoon who is himself an idiot.)
Given the fact that you didn't know what plasticity is, I'm betting on the former. It's kinda strange how we seem to have moved from "Don't believe everything you read on the internet" to "If it's not on the internet, it can't be true."
