This is the complete collection of the series in a nice box set of DVDs which maybe you have seen some of already on BBC America or else on DVD already (it has been available in individual seasons before). If so, you already know just how crazy and downright hilarious this show can be. And this box set also includes a live concert.
True, it may take a minute to get into some of the characters or another minute to fully understand their sometimes thick UK accents, but once you do, you will be hooked and won't be able to stop imitating these silly silly British wits. It is hard -- and sort of unnecessary to describe -- but basically the plot of the show, which was based on a radio series, is that it takes an inside look at some of the strange yet very intriguing and curious characters that inhabit them there British Isles.
Below are some clips to better give you an idea of what to expect from Little Britain, which you should find in the DVD sections at all three Amoeba Music stores.
