Sorry it's a day late, but I've just come accross this clip online. It's Jon Stewart's speech at the beginning ot the first edition of The Daily Show after the events on September 11th 2001. It is one of the most moving speeches I have ever seen.
UPDATE: This video and all Daily Show videos have been taken down by a bunch of bastard Lawyers. It's a shame, it was only generating interest in their channel. I hope the money they enjoy the money they've earned out of this.
