I doubt 'Little Britain in America' would be as totally filthy, scurrilous & outrageous as the real BBC broadcast thing, as the whole premise of the series is an extreme send up of current British stereotypes, political correctness and current Britishness in general, & would be totally incomprehensible to anyone not British, and certainly would be censored or banned by the authorities in the Land of the Free.
However, as usual, Youtube comes to the rescue, in short digestible chunks:
This one, of Daffyd Williams 'the only gay in the village' is typical ( the implicit joke is that Daffyd isn't gay, just Welsh, desperately seeking an identity in a dead & forgotten Province of the UK ):http://www.youtube.com/watch?v=l4zx1ZX8 ... re=related
Lots more clips associated with the above clip there, btw, unless access to certain bits of Youtube are blocked & censored by the US authorities, etc., etc.
Particularly hilarious is Mefanwy's comment: " Think of how much cock & bum fun you could have had " in her mock-Welsh accent.
No doubt baffling to an American.
Try searching for 'Father Ted' on Youtube & you'll get a similar bunch of the best bits. Like this:http://www.youtube.com/watch?v=IvvwNR3vF44
I may be bonkers but at least I'm British.
