The cancelled guest appearance of Presidential candidate John McCain scheduled for the David Letterman show, Sept 24, 2008. In which John McCain phoned Letterman to advise he was cancelling as he had to fly back to DC because the economy was 'cratering' and in crisis ($700 Billion Financial Bailout). Ah, but that same night, John McCain appeared on Katie Couric, and didn't actually fly back to DC until the next morning. John McCain had announced his intention to 'suspend his campaign' (for President of the United States of America) to go to Congress to help out with the financial bailout). Video is of David Letterman's responses on his show as this circumstance was unfolding ....it is too exquisite not to post!
