Ok, forget the embedding, the code you need is in there, but its the url thats easier to work with. The url for that last clip is http://www.youtube.com/watch?v=9u0S3HuCMrg (the "&feature=related" only appears because you have obviously clicked on a related item, so ignore that).
In that url, the only bit of code you need is the bit after the = symbol, 9u0S3HuCMrg.
Take that list of random letters and numbers, and put them between the youtube ubb tags!
