Lots of people refer to this as the funniest movie of all time which is a pretty strong thing to say but I can't honestly think of one that's made me laugh as much as The Holy Grail even 30 yrs. later. The only person I've known who didn't think this movie was funny was my dad who was an occupational guidance councellor at the time. I still remember him shaking his head in dismay as he left a room of hysterical laughter behind him (not really that uncommon).
