Letterman to apologize

Late night comedian David Letterman is taking heat for a joke he made at the expense of the Palin family, namely Gov. Sarah Palin's daughter, Bristol, who Letterman inferred got knocked up during a Yankee's baseball game by one of the players.

The joke was in bad taste, to be sure, but some took greater offense to it seeing as Palin's eldest daughter wasn't in attendance, but that her 14-year old daughter was.

It's pretty clear that Letterman was trying to have some fun at the Palin's expense. He wasn't intending to say that the 14-year old daughter would get knocked up, but rather the 18-year old one who is already famous for having a pregnancy (Bristol).

Tonight, Dave is said to be extending an official apology to the family. It's good that he does, but such jokes at the expense of politicians' children are not rare. Take John McCain's joke, for example, at the Clinton family's expense:

Why is Chelsea Clinton so ugly? Because her father is Janet Reno.

Classy.
