There's such a big lack of good partenting these days it isn't even funny. Parents figure the kids will figure it out themselves, thats why I fear what our generation is going to do when we have one of us as president.
But there should be an instant response in kids and adults when they see the words "[B]Adult[/B] Swim" Kids should think, "Oh, shouldn't watch this" and change the channel. Parents should say, "Better not let the kids see this." and give them a bed time. In reality though, kid sees it, "Oooooh, cool!" and the adult "Ooooooh, cool!"
