Bill Murray was David Letterman's first guest on both of his late night talk shows.
Over the years every appearance turned out to be an event and that penultimate show gave us a compilation of the highlights:
So for the last "regular" 'Late Show with David Letterman', Bill Murray burst out of a cake and proceeded to eat cake off his shoe and be his usual low-key weirdo self.
And then his exit from the set lived up to his reputation with the show - he burst through the "Bill Murray Doors" to the tune of "Power To The People" and rallied the people on the street to his cause: keeping David Letterman on the air.
At the end you'll see and just barely hear Dave tell Bill that he saw him on TV the night before and wondered if everything was all right. "I'm okay," Bill reassured him.
I think this locks Bill's appearances on the penultimate 'Late Show' and his surprise walk-on at 'The Last Word' as the Best Reality Show Crossover for the 2015 Toobits Awards.
