This is as funny as an old article I posted years ago (it is now unavailable.)
That article was about how Al Franken's sitcom (yes, he had one) and set an all-time record for the worst ratings in television history.
I think you are referring to "The Rutles" which was a movie parody of the story of the Beatles, not a series. I wasn't born 'till 15 years after it came out so I'm relying on what I heard on vh1 once.
