yeah...there are 'differences' in humor in different cultures...just read cartoon booklets. or watch imported TV programs...it is not safe to over-simplify it, but the very fact that many Americans love certain English comedies says something.. "Monty Python" is a very English creation, though VERY popular in some circles...

Now 'some' British/English humour is a bit strange for American tastes.."Are You Being Served" just has characters which do not track for many folks
