Many, many moons ago, my best friend Dan and I regularly attended midnight movies. For the most part we saw Mad Max, Dawn of the Dead (original), Life of Brian, and a healthy dose of:
Monty Python and the Holy Grail. The volume at these events was shattering, but we didn't care. You see, Dan and I have . . . let's just say, odd senses of humor.
(We laughed until we almost threw up at the "Bigus Dickus" scene in Life of Bryan.)
Anyway, even though I can quote that movie front to back, I was missing something: Monty Python and the Holy Grail is a rousing good D&D adventure. Think about it. We have:
The Adventuring Party
See above photo. That was a straight up PARTY. It had a leader. It had the talented, but brash warrior. The wise companion. Comic relief. Not exactly your D&D mix, but still all were filling a particular niche and never stepped on each others' toes.
Establishes the leader's prowess. The encounter with the Black Knight shows that while Arthur is open-minded, he is not to be fucked with. Like any good D&D player, when the NPC reaction roll doesn't pass muster, he calls for Initiative.
A Crazy Hermit Gives Enigmatic Advice
How many times have we seen and/or used this old guy, cackling and dispensing enigmatic advice?
(of course this is the bridge keeper, but they are one and the same character)
More of a staple of games played by adolescent males, they did make an appearance.
Break out Gods, Demigods, and Heroes, the party is about to get hit with a divine Quest. What page was Yahweh on?
And the number of the counting shall be three.
I could go on, but you get the idea. It's all there.
