It almost shames me to admit that, despite claiming to be a nerd, I had never seen a Monty Python film or sketch.  Not "Life of Brian," not "Flying Circus," not even that (ahem) Holy Grail of nerdiness, "Monty Python and the Holy Grail."  Sure, I'd heard many of the classic jokes and lines from it, from the Black Knight's hysterical dismemberment to the Knights Who Say Ni (and demand a shrubbery to boot), but I had never experienced it for myself.  And given that it's one of those movies that people either seem to really love or really hate, I was wary about watching it for myself.
