It is a really interesting and funny documentary about a mythical , legendary joke told by comedians backstage for decades, it has an opening line and a punchline and the rest is just improvised filth, to see who can go the furthest and be the most vile and offensive. It is explained by many of the worlds top comedians
It is an original concept for a doc and the subject matter becomes more multi layered as you analyse it.
I have more to say about this but its too early at the moment, Ill be back................
With the joke, I'm sure it's a lot funner to tell it than to listen to it. The goal of the "comedian" telling the joke is to make it as long as possible and with the sickest crap. For me, all the dirty stuff he/she includes in the joke doesn't contribute to the final punchline. It can last five minutes or two hours and the joke will be just as funny, only I'd get tired within the first hour of the joke.
