Here's something to do if you're ever bored at work.
Check out http://www.meriam-webster.com
The site has a feature that will say the words for you to audibly demonstrate correct pronunciation. If you're feeling silly enough, I haven't found a cuss word that it can't pronounce.
If you really need a good laugh, type in "son of a b*tch" or "sh*t"... It's got the normal pronunciation as well as the trailer-park pronunciation.
