Late Show with David Letterman

Dave's worsening eye infection puts him on the bench indefinitely, so scheduled guest Bruce Willis fills in for Daddy. Amongst tonight's highlights: Bruno and George Clarke duct tape plastic sheets on the backdrop; the ""Lean Mean EZ CD Opening Machine"" (a sledge hammer) is demonstrated; Paul interviews Bruce, then Bruce sits in with the band on harmonica; John Mayer performs ""Why Georgia.""
