After reviewing stills of Dave's hand being stitched up, we're ready for the removal of the stitches, simulcast on www.cbs.com/lateshow. In the guest chair is Dr. Lou Arrone; he says Dave "almost cut off the tip of his finger." Dr. Robert Hodgkiss comes out and puts on goofy glasses. The Hi-Ho Babes bring out the medical equipment. Dave plays with special small magnifying camera by putting it in his mouth and down his pants. Finally, all 3 stitches come out. Shortly afterwards, Rupert brings in potato salad.
