They also produced a little booklet for soldiers that's a pretty interesting read. The first few pages are about how England is small but full of history, and that England doesn't like show-offs so the American soldiers weren't to start boasting or flashing their cash etc..
I once heard of a story of a US commander in Italy who absolutely hated his posting because he had several British Empire units under his command and wrote letters complaining about all the different races and nationals with religious, cultural and food requirements he was forced to deal with.
It really highlighted how the British Army had these considerations well established and had little problem with integrating units from around the Empire to work together compared to the Americans.
By 'brought up in a primarily US-centric enviroment' I assume you mean 'brought up in the US'? It's okay, you can tell us, we won't hate you for it. We'll definitely take the piss out of you though.
For sitcoms, the TvTropes article on the subject is surprisingly useful.
Since you'll be staying here for a while, I also recommend you read some anthropology books. 'Watching the English' by Kate Fox is the one I heartily recommend, along with this thing the US government published all the way back in the second world war. It's still very relevant.
Finally, when in doubt, remember this: The British (or at least, the English, I can't necessarily speak for the rest) don't have a specific time or place for humour. It is something that is always on. You remember this fact, and things should be easier for you.
This is cool, and analogous to two reproduction booklets a friend gave me - Instructions for American Servicemen in Britain and Instructions for British Servicemen in France (haven't read the Germany ones). They're surprisingly thoughtful.
and here it is if anyone wants their own copy.
