Stephen Colbert: Senior Fake
IMHO, he is the best part of the Daily Show. (well, Jon Stewart and him are tied, happy?)

He's interviewed by Fresh Air's Terry Gross and it is a great interview where you get some insights into where he finds the vulnerable points to make fun of (hint: hypocracy) and making sure that he is passionate about his humor. I'd definitely like to meet him.

There are a bunch of clips from the Daily Show with Jon Stewart but Colberton (Real Audio Only) is one of his best.

Ok, this one was also really good.

Ok, ok. This one doesn't even have Stephen Colbert (it's Rob Corddry) in but DAMN it is funny.
