I love it when Brits swear.
Well I was in the Royal Air Force and based at RAF Brawdy (West Wales) in the 80s, there were also Americans on the base. In the bar on the base we had a swear bottle, so if you were to swear you would have to out something in the bottle. One evening there was an American servicewoman in the bar and asked what it was, so to was explained that if you swear you have to put something in the bottle. She thought it was such a great idea, she put some money in the bottle and started to swear.
Well, what she though was swearing, she never said a single worn that we (Brits) considered to be a swear word.
