I didn't know you were allowed to apologize to someone while simultaneously making them look like a moron, but David Letterman did just that. On Tuesday's episode of Late Show, Letterman joked about Alex Rodriguez knocking up Bristol Palin. Apparently, Sarah Palin was insulted that Letterman would exploit her children, because only she's allowed to do that. And now, on last night's episode, Letterman "apologized," but really just used the occasion to prove he is a genius…

For Dave, mea-culpa is just another way to say you're-an-idiot. He should run for vice president of fake apologizing.
