DON'T EFF WITH LETTERMAN!

John McCain cancels his interview with Letterman at the last minute, because he needs to "fly out to D.C. to handle the economy". Well, at least that's what he said. Little did Letterman know that McCain was just down the street getting his makeup did for a Katie Couric interview. Well, Letterman finds out, busts him, and comedy ensues for our viewing pleasure.
