Here, in a short clip produced by Heathrow Airport and shown to people on arrival, is a witty look at a few manners which may be particular to Britain.
Stephen Fry really is a bit of a national treasure over here, friend to the Royals, actor, director, writer, comedian and Twitterer. We love him for the insight that he shows us into our own idiosyncrasies, his honesty, reality and laughter.
Feel free to get in touch if you have any specific questions about British idiosyncrasies - we'll do our best to help!
Who else do you think would be worthy of the title 'National Treasure'?
