I think the FCC should stop worrying about bad words and boobs and instead move to ban singing on television dramas.
I've been watching the first few seasons of Homicide this week, and it's really good. The story lines are intelligent and the characters are sharp and engaging. But every few episodes they crack a particularly tough case and go to this bar to celebrate. They drink, and eventually they sing. It makes me extremely uncomfortable, even if it happens in a scene in which characters might conceivably burst into song, like at the aforementioned bar or at children's bedsides (ER was also a major singing offender).
One of the many great things about suspension of disbelief is that it means that well-developed characters don't have to do every single doofy or intimate thing real people do. So cut it out. It's embarrassing.
