David Letterman absolutely tore John McCain a new one on Wednesday's show, after McCain supposedly called Dave at the last minute to cancel his appearance because he had to "race to the airport" to go watch after our crappy economy.

After Dave busted McCain with his pants down, he used the opportunity to rail his elder some more.
