You Tube & Rowan

This post is for Rowan who posts lots of You Tube videos on his blog instead of working on his PhD - alas this will be no more (or maybe just not as often) as he enters the world of work shortly. Don't know that he comments on the videos, but Rowan, I salute you and say "Thanks for keeping me amused with all the videos and distracting me from work. I guess I shall have to find something else to keep me amused now......"
