re: the Nac Mac Feegle: don't forget their newcomer, Wee Mad Arthur, brought up by gnomes (which always makes me think of The Full Monty). Wee Mad Arthur makes a star turn in one of the Discworld books about Vimes and the Watch. But I've forgotten which one it is. Vimes and Colon and Noddy, and the dauntless Carrot, are climbing upon and falling off a roof someplace, and Wee Mad Arthur, who has yet to be recruited to the Watch, turns up and is utterly without fear. Hilarious.
