You first have to look at the link of the video you want to embed, and copy the video identity code. As an example, the ID is highlighted in the three links below:
http://www.youtube.com/watch?v=DvAuqYFVrqI&search= http://video.google.com/videoplay?docid=-8396144199570910608&q=eu http://www.vimeo.com/993998
This is what you write:
You can't be me, I'm taken
But anyway you embed the ID in double parentheses... You can't be me, I'm taken
