Hmm. I don't think David Letterman appreciates being stood up, nor do I think he believes John McCain's sudden "urgency" theory about why he needed to suspend his campaign. Hmmm. Not good. You don't want to piss off the court jesters, Johnny Mac. They are brutal! And to dish on you in front of Bill O'Reilly's sworn enemy Keith Olbermann and to make the Olbermann giggle and invite him to partake in zingers? Consider my jaw unhinged. The boldness! The lack of shame!
