No, I never did. My uncle would occasionally produce his book of materials and correspondence with the OED and flourish it. He specialized in educational and mathematical terms ("Nothing goes out of date faster than educational jargon, or lasts longer than mathematical", he would say to me over the marmalade. He was a math teacher in the British school system). His idea of a good time was to do the Times crossword puzzle in ballpoint pen before getting up for breakfast.
