Yeah. One neat way of doing this is by using this code:
<a class="video" href=http://www.youtube.com/v/XXXXXXXX onclick="return hs.htmlExpand(this, { objectType: 'iframe',outlineWhileAnimating: true, preserveContent: false, width:425, height:355 } )"> LAUNCH THIS VIDEO </a>
Change the XXXXXXX to the Youtube video ID
and change LAUNCH THIS VIDEO to the duh subject or name of video or whatever you want to call the link
