Monty Python and the Holy Grail

The Monty Python comedy clan skewers King Arthur and his knights of the round table as they quest far and wide for the Holy Grail in this inspired piece of lunacy that's utterly quotable -- particularly the bit involving knights who say "Ni." John Cleese stands out as the Black Knight, who suffers gory, slow dismemberment at the hands of the mighty king himself yet maintains that "It's just a scratch" after every whack.
