Many years ago I had a senior, though very quirky, work colleague who had that eloquence / verbosity (I think that is the description) with his words and that delivery which I took for a posh drawl. Now, years later and I often do impressions, with great affection and fondness, of him and I have come to the conclusion he lived his life speaking like WC Fields. And that gives him the last laugh as none of us realised at the time.
