While David Letterman's admission of interoffice romances may have wreaked havoc on his personal life, the extortion scandal paid off ratings-wise again last night. During the first taping since the Late Show host delivered his bombshell to 5.8 million viewers last Thursday, Letterman opened the show with a self-effacing monologue, transitioned into heartfelt apologies to his wife and staff before shifting focus to his guests, Steve Martin and Martin Short. Last night's episode yielded a 4.2 rating which trumped any show in NBC's prime-time line-up. [Associated Press]
