It has been far too long since I read a Discworld novel. Off the top of my head, I would list Wyrd Sisters, The Colour of Magic, and Moving Pictures as my favourites, though my favourite Pratchett moment would have to be either Rincewind's first conversation with a troll in The Light Fantastic (Rincewind says to a tree, "Did you just say something?" "Don't be silly," says a nearby rock, "Trees can't talk.") or the sheer genius of the fifty-foot blonde woman carrying a screaming ape up the side of a tall building in moving Pictures.
It's been far too long...
