David Letterman and Howard Stern have worked together in the business and are also longtime friends. Naturally, the 60-year-old shock jock couldn't help, but weigh in on Letterman's retirement announcement.
"Love Dave, his impact in show business, he has been such a part of my life," Stern told E! News at an America's Got Talent red carpet event in New York City on Friday. "At NBC radio, I was about to get fired and then Dave had me on his show, and he said, 'Hey I think you're great' and he helped me keep my job. My bosses noticed. They fired me later."
As for watching Letterman break the news during Thursday's Late Show, Stern admitted it was "really sad."
"I watched him retire last night and it makes us all feel really old," Stern said.
Age aside, would Stern want Letterman's job and take over the coveted slot?
"I'm so busy with radio and AGT and I've had a few other things going on, and no one has asked me," Stern explained. "And I've been offered talk shows in the past but who knows."
TV's longest-running late-night host in television history said that he will air his final show in 2015.
"The man who owns this network, Leslie Moonves, he and I have had a relationship for years and years and years, and we have had this conversation in the past, and we agreed that we would work together on this circumstance and the timing of this circumstance," Letterman told the audience. "And I phoned him just before the program, and I said ‘Leslie, it's been great, you've been great, and the network has been great, but I'm retiring,'" Letterman said. "I just want to reiterate my thanks for the support from the network, all of the people who have worked here, all of the people in the theater, all the people on the staff, everybody at home, thank you very much. What this means now, is that Paul [Shaffer] l and I can be married," Letterman quipped.
