For your enjoyment and enlightenment: a hangout with a bunch of people involved in the Rosetta project. They are there to give updates on what’s happening.
One of the people is Matt Taylor, he of The Shirt. Starting at 15:20 (which is the first time he talks) he apologizes for wearing The Shirt. Good; thanks, ESA. Then he collects himself, and gets a pat on the shoulder from the guy next to him, and then he talks about the project.
Good. Done. Now we can talk about the project and leave The Shirt behind!
