I just watched this really good 20 minute video by Mike Rowe (he’s the Dirty Jobs guy). I warn you, it is a bit PG-13 for some farm animal stuff, but it is really well worth it. I love what he has to say, and he is far more intelligent than I ever gave him credit. Actually, guys like him are often far more intelligent than most of us give them credit.
In case you are wondering, I didn’t embed it, because it only embeds the first half to try and drive you to the Fora site–kinda annoying, if you ask me. It is better to watch it all in one place.
