IGN - I don't know where to begin this week. Should I talk about how hard it is to see Don becoming so out of touch and so… uncool? Or should I simply go crazy over the fact that MR. BELDING WAS ON MAD MEN?! It was a brief appearance, sure. He was disturbingly overweight, sure. But it still doesn't change how amazing it was to see Dennis Haskins in a scene with Jon Hamm as Don Draper. I'd like to believe Matt Weiner is a huge Saved by the Bell fan and that's why Haskins appeared. In fact, I will choose to believe that.
