5. ‘Monty Python and the Holy Grail’ (1975)
Memorable quote: “We are the Knights who say... NI.”
Laugh factor: “Monty Python” fans unite! While the comedy troupe’s “Life of Brian” is considered by some to be the better picture, this may be the most quotable film ever produced. The holy grail of comedy films? Close. Now go and boil your bottoms, you sons of silly persons.
