Me again. Sorry if I'm becoming a thread-hog, but I found the speech in which Twain quotes Bill Nye's quip about Wagner (okay, so I'm just a little obsessed!).
Here's the excerpt: "Why, General Porter stands up here, and he also throws out very nice things, and sometimes they suggest Wagner's music from the pen and point of view of Bill Nye. Bill Nye said that he had heard that Wagner's music was better than it sounded. You can take what General Porter says in the same way."
Now that I've beaten that subject into the ground, I'll go away quietly and give someone else a chance to post! :^)
