Do not meddle in the affairs of wizards, for you are crunchy and good with catsup.
Do not meddle in the affairs of dragons, for you are crunchy and good with catsup.
Even I, with my pitifully weak Google-fu, can determine that 'dragons' version is more popular today. In my own arrogant opinion, the wizards version is more clever; it is closer to the original wording, and wizards are more likely than dragons to use catsup. But what I really wonder about is the origin of the quote, and which version is the original. I am fairly sure I encountered the 'wizards' version first, before 1980, and didn't see the 'dragons' one until around 1989. But my memory is unreliable and my experience isn't definitive.
Anyone out there have an opinion, or better yet, evidence, on this burning issue?
(By the way -- it is not in Bored of the Rings. I was positive it was, but it's not, unless my edition has been expurgated.)
