I have DVD boxed set as well. I worked my way through the entire series, in order, over the course of several weeks.
I'm old, so I remember when Monty Python's Flying Circus, the television show (the group itself is Monty Python), was still relatively new and unknown in the United States. Early 70's, when TV Guide was still the only way you knew what was on TV, and the local public television station from MSU had only recently started listing their content. They probably either didn't have enough to warrant it before, or it the schedule itself wasn't consistent so there was no point. This was when TV stations went off the air at night, and public TV stations had even shorter hours.
The last thing on Sunday nights, at 10:30 PM, was "Monty Python's Flying Circus - Satire". There was always a descriptor, "Comedy", "Drama", "News", "Religion", etc. I didn't know what "Satire" was, but the name of the show practically begged me to check it out.
Oh man. This is insane! I had never seen any British television before, let alone British-style humour, and this just blew me away. I was maybe 12 years old. It was like nothing else I'd ever seen. Years later, in English class in high school, we had a short unit on some of the "lesser" genres of literature. Every literature class covers poetry and stuff like Shakespeare and Thomas Hardy, but this took a look at political, metaphorical, satire, those guys. "Satire"? And I remembered the TV Guide listing which said that "Monty Python's Flying Circus" was satire. I'd just thought it was comedy. But apparently someone at TV Guide, or perhaps the person who submitted the listing to TV Guide, considered Satire important enough to distinguish from generic comedy.
And it's true. Monty Python is like nothing else in the world of comedy.
