NEW YORK (CBS) Howard Stern owed David Letterman an apology, and gave it to him during an appearance on the "Late Show" Thursday.
The shock jock wanted to say sorry for something that happened many years ago.
Early in both of their careers, Letterman used to call Stern at home. Stern would then talk about those conversations on his radio show, which upset Letterman and led to the phone calls stopping.
"I really want to apologize to you for doing that," Stern said sincerely. "And if you should call me again, I would not reveal what you said."
