The curious case of South Carolina Governor Mark Sanford (who it turns out was just kicking back in Argentina for a few days without bothering to inform his wife and kids) and the unfortunate case of Jon & Kate Plus Eight dominated the late night shows. Conan O'Brien was able to showcase his physical talents while announcing that the chick with eight kids is now available!
Jimmy Fallon was brief but punchy when he discussed how this was the only time that Jon had failed, although he didn't quite put it that way.
Jon Stewart must have been feeling good because the combination of the Sanford story and the subsequent Fox News analysis always makes for a good thing. He also had correspondent Wyatt Cenac out on the Appalachian Trail in search of the missing Governor, and Wyatt couldn't get spit out his theory about why Sanford had disappeared without briefly breaking character.
Letterman and Kimmel took shots at George Bush, the lack of virgins for martyrs these days (the economy and all), and kids using ice cream in the wrong way.
