Mike Rowe, the host of the TV show "Dirty Jobs" is a surprisingly eloquent guy. In this TED talk in December 2008, he talked about people with dirty jobs, questioning one's assumptions, the nature of hard work, and the "war on work."
I learned a lot of new things by watching this video clip, including how to properly castrate lambs (hint: yanking 'em out with one's teeth is one of the steps)
