Whereby I say in response to someone questioning the source of that quote: "That's the best you're going to find, some journalist's reminiscence twenty-some years after the fact. So I would caution anyone to be wary of whipping that quote out to make a point."

Until I hear of a better source (and I won't), I am putting this quote in the "urban legend" bucket. All that's missing is an attribution to Mark Twain.
