there are some python films that i saw over and over again through my teenage years, and there are some that i saw once or twice in elementary school, and there are some that i haven't seen at all.
i do know that i saw the life of bryan when i was very very small, but i don't remember seeing it twice, and i remember thinking it was kind of slow-moving and not very funny. granted, i may have missed some context, given that i was about ten years old or something. but, it hasn't really come up much, since.
i don't really feel that missing a reference, however disingenuously cited, is particularly damaging to my credibility, and i apologize if you disagree and feel that it's absolutely pertinent, but i have to think you've somehow lost the plot if that's your takeaway from the process.
my father would have no doubt been quickly on it, but it's because he actually lived through it. my own knowledge of the troupe is mostly second-hand, given that i was born in 1981, which was after their most well known work had already been completed.
