 So you probably know now that Bob Newhart, he died yesterday. He was 94 years old. He was a wildly successful comedian. He had two hit TV shows, countless hilarious stand-up routines. But what you may not know is that Bob Newhart, with his dry sense of humor, was actually good friends with Don Rickles. Don Rickles was loud. Don Rickles was in your face. He was bombastic, with a bombastic sense of humor, by the way.
