      Dave reports CBS sales figures the Late Show has run about $750,000 worth of free Gap® commercials so far, and for the first fifteen minutes of the show Tony accounts the free items Dave may or may not be receiving (a $640 value).  In honor of having "Gap Girl" Melissa Bernheim on the show tomorrow night, George Clarke does his own version of the scintillating commercial.
