The Monty Python TV series. Amazing and SO influential! Watch out for all the things nicked from it by others later. One of many was reference to a "Bewilderbeast" ! Ah Badly Drawn Boy I thought... no doubt some smart arse will come along and tell me python also nicked it.... So many others as well though! "wasn't there a person of that name in that 90's film? and "wasn't that the title of thingys 3rd album?" etc right through it!
It's very sexist, racist and any thing else-ist they could get in really and I've no doubt would actually be illegal today! And all the better for it as even the most extreme bits are tongue in cheek and intended to offend the easily offended of "the establishment" (no not the club). It really does make modern TV look pretty tame!
