I've been going through the manuscript for the book making up a list of glossary words (a frighteningly long list), and also noting miscellaneous pop-cultural references-- quotes, direct mentions, paraphrases, etc. I'm sure I've missed a few-- many of them occur in section titles, which my eyes tend to slide right over as I read (in the previous book, one section was titled "Clever Section Title Here" until distressingly late in the process)-- but for your amusement, here's what I have at the moment, in approximately the order in which they appear in the book:
- Star Wars
 - The Adventures of Buckaroo Banzai
 - George Carlin
 - The Music Man
 - Pardon the Interruption
 - Groucho Marx
 - Lewis Carroll
 - Tom Waits and/or Norah Jones
 - William Butler Yeats
 - The Rolling StonesCrystal Gayle
 - Sherlock Holmes
 - The Triplets of Belleville
 - The Princess Bride
 - The Eagles
 - Trent Reznor and/or Johnny Cash
 - Neil Young
 - They Might Be Giants
 - Terry Pratchett
 - Elvis Costello
 - Sesame Street
 - Peter, Paul, and Mary
 
I suppose this list might provide some sort of insight into my psyche, but I'm not sure what beyond the fact that I have too many snippets of pop-song lyrics occupying neurons that might otherwise be used for something productive. I probably ought to offer some sort of prize to whoever can correctly identify all of these, but since nobody else has the full manuscript yet, I won't bother.
