Top Fives meme

I am feeling fairly bleeeurgh. The solution for this, as we all know, is a meme! And I'm going to go with my favourite. This is the one that lets me enthuse about things I like and admire my flist's creativity in requests. WARNING: if you ask me for book-related favourites, there is no knowing how long I might talk!

Ask me my top five favorites in any category. Anything.
