title: How does YouTube get its player embedded as iframe in the Facebook wall?
body: <p>I'm wondering how to embed some HTML code in a facebook post on the wall..
  I've already searched for that and came to the conclusion that ATM it's not possible (Am i right???)</p>
  
  <p>But inspecting the code of the facebook news feed page i have noticed that a YouTube video was coded as an <strong>iframe</strong>!
  What happened there?</p>
  
  <p>Thank you</p>
