Some of the TV show is a bit hit and miss but it always was -- if you know any comedy sketch show as it were that was wall to wall hilarity for 4 series (some 45 episodes, each up to 30 minutes a piece) then please please please do share with the class. Alternatively there was a nice compilation film called And Now for Something Completely Different which was somewhat panned at the time for being just a compilation of things people had likely been watching on their TVs for the last however long (rather unfortunate given the name) but today serves as a decent compilation.I really have to watch Monty Python. Has it aged well? Still good?
The standalone films are still spectacular and probably will be for generations to come. We can probably get in a nerd fight over which is best but I will watch any of them if given half a chance.
I might also suggest their live at the hollywood bowl... I guess it would be called a special these days. The audience participation/interaction stuff alone is something I did not expect from them, and as I sit here there are maybe 5 comedians I know of that do it as well or better as part of the act (if you count dealing with hecklers there might be a few others that are as sharp).
