Ok, this is just off the top of my head. I didn't see Letterman when he told "the joke" and I didn't see him when he apologized and I know that much is told non-verbally so I just have to go by what I read here. My first thought is: at least he said that much. I just assumed he didn't feel bad at all about saying something like he did about Sarah Palin's daughter.
If you don't know what I'm talking about well, good for you. Nevermind. Don't worry about it but most people have heard that David Letterman said something offensive about the Palins. To tell you the truth, I wonder when people are going to quit taking seriously what "famous" people say. He's a stupid comedian who went for some cheap laughs by taking a shot at somebody else that is famous. Did he mean for the joke to be about the 18 year old or the 14 year old? Who knows? Who cares? What's really the difference? Yes, it's tasteless and offensive but get over it. That's what people like him say.
I'm a big Palin fan but honestly, she probably overreacted. I'm not cutting Letterman any slack. He never should have told that joke but Palin should have never let it escalate to this point. Maybe I want to live in a perfect world but people have more important things to do than wah wah about people saying mean things. Put your big-girl panties on and show people that you have style and grace even when your name is slandered and your feelings get hurt.
So, my point is that at least Letterman apologized. Could it have been better? Yeah, sure. Did he really mean it or is he worried about his ratings? Eh, probably a little bit of both. Who knows? Who cares? Let's go to sleep and tomorrow we fight bigger battles. Like...how is Teddy ever going to get home?!
