I loved the evil Willow ep too; for some reason, though, I was thinking about Spike's "Bloody hell, I'm British!" the other day from Tabula Rasa and totally cracking up. XD

(Tabula Rasa, in general, was an episode that I thought should've been either angstier or funnier than it actually was; parts of it were a lot of fun, and the comedy potential was through the roof, but in general I remember being vaguely disappointed that they didn't use all the potential to better effect, either to explore the characters or just to do flat-out hilarity. On the other hand, Spike thinking he's Giles' son from the accents is probably worth the price of admission all by itself. *g*)
