Yeah, not even ONE quote from the most quotable movie of all time...Monty Python and the Holy Grail. What's up with that? :-)
(As I said in a much earlier post, Casablanca deserves all the mentions it gets and then some. A newbie seeing the movie for the first time would think it one giant cliche precisely because so many of those lines have been quoted and/or reused numerous times over the years.)
