Well, I think that the movie description on IMDb pretty much provides you with any basic information regarding the theme of the movie. It doesn't really have a plot and is mostly told in a documentary style fashion, but without any one narrator.
In essence, a group of comedians are all discussing this famous (apparently only to Hollywood folk) joke that has been told for some time now (I think that they reference the very early days of Hollywood and even vaudeville) primarily by comedians and typically behind the scenes. The main areas being parties, pre show discussions, post show discussions, and get togethers where any group of people include a comedian.
While I did find a few of the retellings to be funny, and a few of the comedians were just funny because of who they were, I found most of the actual dialogue to be in extremely poor taste and felt that this could have been more in the lines of a 20 minute to 30 minute short instead of a full length documentary as there is only so much perversion that can really take place in one period without fully overloading most people.
A general warning should be given up front, this is most certainly not a show for anyone under the age of 16 as it contains graphic descriptions of the most vile deviant behaviors imaginable.
Overall I don't recommend it, but I do give it at least a 4 out of 10 due to the partial comedic factor and the history lesson included.
