That's Funny?

Letterman showed his old ass and is now getting some heat for it.

Just now on O'Reilly's show asshat apologist Alan Colmes said he probably just mistook Bristol Palin for her 14 year old sister Willow.

Because, you know, teen pregnancy jokes are funny when applied to 18 year olds, but just creepy for 14 year olds.

There's probably a good reason why Letterman still hasn't landed that "Tonight Show" gig.
