Ignoring the Bully?

I just watched the video accompanying this article and found this a little insane.  At the same time I also saw clips from the same G20 Summit earlier today, showing Bush greeting each foreign ambassador one-by-one.  He could have just gone through that line of introductions and doing it again was redundant here? 

Bush fan or not, we all know the man's approval rating is low.  Still, I have my doubts that these representatives would refuse his handshake and can't decide if this is deceptive journalism or just really embarrassing: http://www.huffingtonpost.com/2008/11/20/world-leaders-dont-shake_n_145141.html.
