I don't believe he's sorry for what he said, nor is his wife, they're sorry they got called out on their bull. Sorry for themselves, not for the people whom they offended. I'm sure behind closed doors there is nothing but more of the foul crap that we have already heard too much of.
In the end, I'm glad his kids get to see the backlash from this, it is possibly the best lesson they can learn from this experience. It is not cool to treat others that way, and you pay for you behavior in this world. I just wonder if their children are getting any backlash at school. Like I said I only saw a few minutes of the episode, and will not be watching it when it repeats, but it seems from the comments here that they were chips off the old block so to speak.
