I have a feeling he's said Vimes as well, but can't remember where or when. He has certainly got a good deal of Vimes's cynicism. I remember at an event, someone coming up to him while he was sitting quietly in a corner with his laptop. They asked him if they could have a chat with him. He stopped what he was doing, looked at the person and said - "certainly, if you are prepared to make me stop writing the next book."
That person went very red and left him to it.
