Palin Letterman joke

There is some stuff going around about Letterman and Palin. I will attempt to clarify.

Letterman said "during the game Sarah Palin's daughter was knocked up by Alex Rodriguez. You can see how that would be awkward."

It was a joke. Mr Letterman was not saying that Sarah Palin's daughter was raped. He was not saying that he wants to have sex with the girl. I know that the 14 year old was the one at the game, but the joke obviously referred to the older daughter who was, in fact, knocked up.

I don't expect you to like the joke or find it funny. It is ok if you hate the joke. I hate a LOT of jokes, but it is a joke.
