In the Great McGrady when the kids were having a fantasy about Mrs. McGrady dying of cancer. There was a scene of McGrady walking down the hall into some bright glowing light effects at the end of the fantasy. But the efx were removed and I believe the scene may be gone entirely in the final cut. Anyway that whole show is not airing now because of the Lance Armstrong cheating admission.
I think I see what you're talking about...This fantasy?:
http://www.youtube.com/watch?v=yfZgS6QYAlA#t=8m18sAt 9:09, was that green wall at the end of the hall added in to cover up the "light effects"? It looks like it. Never noticed that. Now we know why Francine was so overwhelmed from that dream. Was the dialogue about Mrs. Macgrady changing jobs added in as well? Because it doesn't really the fit the original context of her supposed to be "dying".
