A segment from The Colbert Report called Cheating Death.
From his website, it looks like he does one of these segments every week or so. In this version, Stephen Colbert plays up on our fears of being out of control of our health—due to factors like chemicals in our environment, specifically the water supply in this case. And then goes on to make jokes at the expense of the ways we try to extend life and make ourselves look younger, even taking it so far as to extend the craze to pet health. The latter trend fits more with the title of the topic "cheating death." In typical Colbert style, it is drawn to absolute absurdity. It's pretty darn funny.
