CBS Evening News frontwoman Katie Couric can be seen aping Dan Rather in a new video circulating on the Internet. ( Watch it here.) With the camera rolling and as she prepped for a remote broadcast, Couric is seen saying, "I'm going to be like Dan Rather on YouTube," referring to a clip that circulated last month showing Rather fiddling with his overcoat and fussing over his appearance. "Geez, don't you think he deserves a little payback?" Upon completing her shtick, Couric declares, "This tart is ready to go!" - an allusion to dismissive remarks Rather directed at her this past June. What do you think? Did Dan have it coming, or did Katie cross the line of journalistic integrity?
