Conan O'Brien will give his first interview since he left NBC to CBS's 60 Minutes Sunday. O'Brien, as part of his severance package, agreed not to give any TV or print interviews until May 1. The segment will include clips from the comedian's "Legally Prohibited from Being Funny on Television Tour," but will focus on O'Brien's view of the controversy surrounding his departure from the network that was his home for 17 years. The tall-haired comic is still barred from snarking on NBC or Jay Leno, the man who replaced him at the Tonight Show, but he "flirts with the restrictions," CBS reporter Steve Kroft says. O'Brien will also talk about his new TBS show. Ironically, CBS will have a hard time promoting the show this week, since it's not yet the first of May.
