Whatever hard feelings exist between Jay Leno and David Letterman melted away last Tuesday when the two old friends -- plus Oprah Winfrey -- gathered in New York to shoot a much buzzed-about Super Bowl commercial. Both comedians talked about the ad on their respective shows Monday night, but it was Leno who spoke on a personal level about the meeting.
