There are not many TV shows I watch religiously... The Daily Show, Colbert Report, The Simpsons, South Park, and a couple others.
I like the programming on the Discovery channel, but there is one show that I have become a big fan of - "Man vs. Wild". It is basically a show where a former British special forces soldier is dropped of in some extreme location & has to survive to find civilization. I had no idea that the host's name is Bear Grylls, but it just makes him that much more awesome.
