Welcome to Week 19 everyone! The theme of this puzzle was inspired as Puzzle #11 was coming up, but I decided to put a bookmark in it and to come back to it later. Also, it gave me a reason to use the Schoolhouse Rock title.
Next week is Week #20, which means another meta puzzle is on its way. Also, a week from today is the kickoff to the USC Puzzle Hunt! As of right now, 24 teams have registered, and it looks like we already have a great field. Be sure to get some of your puzzle friends, sign up a team, and enjoy some puzzles mostly written by yours truly!
