David Letterman calls them Jokes. I think David Letterman's dictionary is broken, and he needs a new one. When you tell a joke it's supposed to be funny. Something to chuckle at.
David Letterman's explanation NOT an apology was that he meant Governor Sarah Palin's eldest daughter was the butt of his knocked up by A Rod Joke? Funny.....Nope, still not getting the funny part. It appears to be funny to some people because I have read comments, that suggest that if the Governor takes her children on the campaign trail or to a baseball game, her children are fair game. So Dave the Governor of Alaska took her kids to a baseball game in NYC, and in typical New York humor and hospitality, you decide her daughters were "ASKING FOR IT" Imus got fired for less.
