Going back a few years, I can remember some Americans telling me that they 'loved British TV comedy'. Turned out that what they liked was the mildly risqué comedy of programmes such as 'Are You Being Served?' and Benny Hill. Such programmes weren't known in the US - the advertisers, who were paying for the programming, wouldn't have been happy with what might have been seen as 'non-family' humo(u)r. For a time the 'Carry on' films had a bit of a cult following there as well, for the same reason - their raciness was something that was not always allowed to US film-makers.
Essentially, comedy is very local. We like 'Fawlty Towers', for example, simply because it is so British. We are laughing at the faults we see in British institutions. Essentially, we are laughing at ourselves. British sitcoms such as 'Steptoe and Son' and 'Till Death do Us Part', for example, which have succeeded in the States, have done so after they were adapted and renamed - 'Sanford and Son' and 'All in the Family' respectively.
Comedy seldom crosses borders, if it relies heavily on situations and background. I have tried, without success, to find anything vaguely amusing in episodes of 'Friends' or 'Seinfeld' that I have watched, even though people have assured me that they are 'brilliant'.
I have shown the Eric and Ernie 'Stripper' sketch to students in Thailand. They found it hilarious; another one which they like is the 'Talking Moose's Head' from 'Fawlty Towers' (the 'Germans' episode, I think). And Thais love Mr Bean - everybody knows Mr Bean- students, taxi drivers, even a monk one time asked me if I had ever met Mr Bean! Universal comedy. Obviously anything which depends on wordplay (Four Candles) or on knowing the identity of a celebrity ('Andre Preview', Glenda Jackson) is much more difficult to appreciate.
