Too much T.V.??????

So the other day Britt and I were sitting outside together just talking. I happened to notice his permanent front teeth were a little yellow. Remembering that he was the one who had cavities at our last dental visit, I said..."Britt, you need to make sure you are brushing your teeth really good. They look a little yellow to me." Then in all seriousness he said, "Oh, do you think I need to use a little Polident? They say, that is the best way to get your teeth white." I could not believe my ears. Did my 7 year old really know what that was? Where did he learn that? Of course...I find out it was on a Food Station commercial on the T.V. Go figure.
