Legendary comedian Bob Newhart returned to my show this afternoon to promote the paperback edition of his book, “I Shouldn’t Even Be Doing This!”

We talked about his friendship with Johnny Carson, and he told some stories from the more than 100 times he appeared on “The Tonight Show.”

That led to a discussion of those rare nights when the act isn’t working and he’s bombing in front of an audience. To my surprise, Newhart says he still gets nervous about two hours before he does a standup concert.

Listen to our conversation here.
