I've been going through all the Vimes novels in order - all the DWs are fun, but Vimesy is my favorite. And I know what you mean about Pratchett - how he can make his characters so great and so dumb at the same time just boggles my mind.

(Heh. It was kind of exhausting playing Spock, like writing essays. He was hopelessly dry without his crewmates to bounce off of. And none of your characters here or there play the same! Even if you have them in the same thread.)
