But what country could have produced "Airplane!", or "O Brother Where Art Thou?"
You could say that something like "Seinfeld" (and "Curb Your Enthusiasm") is more the product of a very unusual subculture (in fact, this is the basis for much of the humor, how poorly new yorkers fit in the rest of US culture), but keep in mind Seinfeld had the highest ratings of any sitcom in US history, so the appeal is obviously very broad.
To be clear I wasn't talking about humor in media - of which there are a lot of excellent examples, but the amount of humor that seems to be part of day to day life.
Incidentally, I wouldn't regard Monty Python as being very representative of "natural" British humor - I'd probably suggest Al Murray in his "Pub Landlord" persona to be far more like the comedy you are likely to encounter in real life (or Frankie Boyle for us Scots).
