All,
I noticed that the Marathon did not show the episode where Grady was taking care of Lamont, and Lamont was being bullied by this guy at a bar, because Lamont was liking this bullies girlfriend. They didn't show that one on the Marathon, and I wonder why. It also makes me think that more episodes probably didn't get shown.

You have to remember that they showed 96 eps out of 135 eps on this marathon. I bet it was an older marathon that they showed and maybe they only showed the best eps possible during the marathon. I really don't know.
