"...the US gave us Twin Peaks"

I had almost forgotten that... it WAS exceptional, but even here it got only a cult following. You really needed to see all episodes in order to follow the plot...much as I guess it is with "Doctor Who". I have friends who follow THAT fanatically, but I never was able.

John is correct that 'humor' and cultural norms differ widely in various areas of the US, and advertising on TV shows is often contrived and changed for the same program in different parts of the country. I simply could not live in parts of the Deep South.. I know HOW to avoid certain issues and jokes, but it's too much strain to do every day.

I see very few American comedy shows that I consider really funny any more here...they are either totally based on sexual innuendo or aimed at stereotypes so blatant that they are painful. The UK has sent us several that were truly 'different', and several that were just UK versions of stereotyped running jokes..("Are You Being Served")
The shows which depend on knowing the accent, vernacular and slang of the UK go right by me.

Yes John, it IS amazing we are able to communicate at all!
