David Letterman

David Letterman's final Late Show was watched by 13.76 million viewers, making it the Late Show's largest audience since Feb. 25, 1994, on a night that saw CBS' coverage of the Lillehammer Olympics.

Not coincidentally, Murray also was Dave’s very first guest when Letterman made his broadcast TV late-night hosting debut on NBC’s Late Night, back in February of 1982. Murray made good on his threat to Dave back then to “make every second of your life from this moment on a living hell,” smearing Letterman and his snappy suit in a cake-infused hug (Letterman changed suits after Murray headed out to protest).

“Everything he did seemed wrong. He didn’t look right. His manner, his affect, everything seemed wrong because he was so profoundly original.” That’s Conan O’Brien talking about David Letterman, the gap-toothed Indiana weathercaster who went on to become the longest-serving late-night talk show host in TV history, ending his run this week at more than three decades.
