Einstein refused to take an iq test.
About wealth,
Einstein spoke more French than English, but, stuck mostly to German. Other languages made him quite nervous. I don't think that he spoke in big words, either, but, he did fill out his ideas.
And, oddly enough, his lines don't seem to yield any neat anagrams. Ha. Might mean a different propensity for the alphabet than found in normal speech, or, to do with the translations from normal speech.
