ANFSCD is pretty hilarious - along the lines of The Hollywood Bowl. I also have all but 14 Flying Circus episodes that I downloaded via P2P (can't buy them anywhere!).
If you enjoyed those, you should check out The Meaning of Life.
Terry Gilliam (12 Monkeys) also directed some other movies, including Brazil, which IMO is truly outstanding; definitely worth a viewing, but it's not your standard comedy fare. In fact, it's hardly comedy.
A Fish Called Wanda, on the other hand, is a riot - "contemporary" Python humor, if you may.
