I really liked that episode too. I loved when Mack acted like he was going hunting but was really working. I hadn't expected that and I was wondering why he was whining so much when that guy tried to pop his shoulder into place. I loved it when he popped it in himself when the guy wasn't looking. I think it is a really good show and it is doing very good in the ratings.
I'm digging this one up from the grave but man tonight's episode was rough. First time I can remember tearing up while watching a TV show.
