In an interview that aired Sunday, Fox News's "Media Buzz" host Howard Kurtz asked his colleague Bill O'Reilly about his feelings toward MSNBC.
"The only thing that I don't want is personal attacks designed to injure," O'Reilly said. "If I see that over there, I'll dip in a little bit. But Chris Matthews saying 'let's write a book: Killing O'Reilly,' I know he's just kidding around. I'm not going to make a big deal out of that."
It was back in October that Matthews mocked O'Reilly's "Killing" book series. "When are we going to have the book we’ve really been waiting for, Killing O’Reilly?” Matthews said while on Comedy Central's "Colbert Report."
