David Letterman was suffering from both a hoarse voice and a cold last night, and his main guest, comedian Chris Rock, saw that as an opportunity to mercilessly mock the talk show host's messy personal life:

"Dave, what the hell happened to your voice?" Rock asked. "You're still doing the show? You're a rich man, you could just go home!" Then Rock sniped, "Wife still mad at you, ain't she." Rock also joked that Letterman had "fired all the cute girls" that used to be backstage. Now it's just "a bunch of fat old guys," he lamented. Of course, Letterman had a comeback for that.
