I happened to watch this episode last year. It took a little time for the DVD of the season to come out, for the library to buy it, and for me to remember to request it, but now it's here.
You're probably getting tired of hearing me say this, but I don't actually know this show very well. All the same, I appreciate the humor in this episode, which plays with the idea of The Curse of The Scottish Play. I've extracted the Shakespeare references from throughout the episode and put them together in one convenient clip. Enjoy!
