Last night’s episode of David Letterman’s The Late Show on CBS scored a 4.2 Nielsen rating, a significant boost from its usual numbers and higher than anything rival network NBC had in prime time, according to the Associated Press. On Monday night’s program, a repentant Letterman served up jokes and contrition in equal doses, saving his most heart-felt apologies for his wife, Regina Lasko. Monday’s show was the first that the 62-year-old late-night host had taped since his admission on Thursday that he had had affairs with women on his staff and had been the victim of a $2 million blackmail threat.
