I watched an episode last night where they were on a Hawaiian Island. They had found a spear head earlier in the day and when they reached the place where they were to camp for the night, Cody says something along the lines of "I'll make shelter and you find water". To which Joe responds that "the top priority is to get a handle on the spear so they can fight off wild pigs and while he is doing that Cody should multi-task on the shelter and water" Then he makes the statement along the lines that "water is a luxury, a defensive weapon is the #1 priority".

I've always liked Cody and I liked Dave too. But that simple stance killed all of Joe's credibility. I respect his service and think he'd be great to have around if I was down behind enemy lines, but for advice on a survival situation I might find myself in, he has no credibility IMHO.
