Okay, here we go, trying to link to video clips on the Comedy Central website. The opening segment of last night's Daily Show is there in two pieces. The first, entitled "Inarguable Failure" contains Jon Stewart's desk comments. I think this link should take you to it, and don't be surprised if you have to sit through a brief ad first. Then, you'll want to watch Ed Helms's report, which they call "Beleaguered Bush" and I think you can do that with this link and (again) sitting through an ad.
Linking to clips on the Comedy Central website is, as we all know, far from an exact science. So if my links don't make it happen for you, just go there and look around for the Daily Show clips with those titles. It's worth the trek.
