In an appearance on Comedy Central’s “The Colbert Report” to promote his book “Tip and the Gipper: When Politics Worked” on Wednesday night, MSNBC “Hardball” anchor Chris Matthews addressed Fox News Channel’s Bill O’Reilly’s “Killing” series of books, saying “When are we going to have the book we’ve really been waiting for, “Killing O’Reilly.”

O’Reilly has claimed on numerous occasions that his latest effort, “Killing Jesus,” co-authored with Martin Dugard, had been divinely inspired. “The Colbert Report” host Stephen Colbert asked Matthews if his work is divinely inspired, to which Matthews replied with the joke:

MATTHEWS: Unlike O’Reilly, who gets it from up there, I kept notes.

COLBERT: Oh really. You’re not inspired by God to write a book? By the way, why didn’t you call it “Killing Tip and the Gipper?”

MATTHEWS: When are we going to have the book we’ve really been waiting for, ‘Killing O’Reilly’?

COLBERT: I’m not saying it wouldn’t be a big seller, but it might be a little cry for help.
