At last, living up to the title, here is a video about swearing. This definitely not suitable for work or playing in front of your mother.
At last, some bad language on Bad Language.
(And the personal bit: this reminds me of when I was working on LEGO Loco. The game let players send little postcards over the internet by dropping them into a goods wagon on a train. LEGO were anxious to prevent this being used to spread profanity and wanted us to add a profanity filter. We asked them for a list of forbidden words and they gave us a couple of dozen. You know, the obvious ones. I didn't think this was going to be good enough so I got my programmers to email their favourite rude words. We soon had a list of hundreds of words. I guess the points are 1) any word can be a swear word in the right context and 2) there are lots of them and 3) they are a natural part of language.)
