Monty Python's "The Black Knight"
As a kid, I remember being at a friend's house and he put on "Monty Python and the Holy Grail". I had never seen anything like it in my life!
I didn't really know anything about Monty Python then, so I was wondering why all these bizarre things were happening. All I knew is that I was laughing and having a great time.
There were a couple of moments in the movie where I really "got" the spirit of what this thing was - the Killer Rabbit... and of course, The Black Knight. Good times :)
