Neil Shubin, one of the team who uncovered the "fishapod" Tiktaalik in Canadian Nunavut, was a guest on the Colbert Report. I can't imagine trying to defend scientific research in the face of Colbert's manic questioning, but dang if Shubin doesn't do a great job. He's got an answer for everything. In the combative atmosphere of faux talk TV, this paleontologist holds his own. I saw Neil speak at NSF last year, and he did a great job there too, even with a much more receptive audience.
