david letterman (don't vote for mitt romney)*David Letterman is known for raking his guests and potential guests across the coals to get a rise out of them and a laugh out of his audience. But, this time it seems that someone is dissin’ him and ignoring Letterman’s attempts to get him on the show.

According to Letterman, Mitt Romney has been ignoring his requests to have him on his show. And in typical David Letterman style, he is instigating a riff n appearance by agitating the republican presidential nominee by telling his audience:

“The current president, President Obama, was on the show last week. The challenger, Mitch Romney, has not been on the show…. He’s got 39 days! Now I don’t wanna persuade anybody unnecessarily, but if he’s not here in 39 days, don’t vote for him!”
