I don't watch CNN, but I heard about it on Good Morning America (I don't watch that either but it was this morning when I rolled out of bed).
I understand that it was the producer of the televised convention who made the remarks. He was being interviewed as the convention ended. He just forgot he was live on mic and started yelling at the "balloon people" to let the balloons go.
I hear it all the time, from all ages ... young and old, both genders, all socio-economic backgrounds, all level of celebrity, all anybody, anything. I'm not saying that that makes it okay, it just doesn't bother me enough to be making news stories about it.
I'm glad Charlie Gibson found the story somewhat humorous, or seemed to anyway. I would have thought he lost his mind if he was angry about it.
