"I knew exactly what I wanted to be. My sophomore year in high school they offered a speech class -- public speaking class. So I signed right up. All right, first day of class, everybody has to stand up and give an impromptu speech about themselves. And I got up when it was my turn and I gave the speech -- it had to be, like, two minutes or something. And I sat down and I said, 'Wow that was easy,' to myself."

Bill Murray, Letterman's first guest in 1982, also made a guest appearance last week, as well as Bob Dylan, who has not visited the show in 22 years.

Letterman's legacy is undeniable. Running a show for more than 6,000 episodes, 4,600 top ten lists, and 20,000 total guest star appearances and raking in a total of 16 Emmy awards, David Letterman is the longest-running talk show host in television history. For the finale tomorrow night, CBS promises to offer memorable highlights and surprises.

As the world watches Letterman for the last time tomorrow, few have the added honor of actually being there as audience members. CNN Money interviewed a few of the lucky fans who got tickets to tomorrow's show, and everyone was ecstatic at the thought of watching their dear Dave go up on air for the last time.

CBS recently announced that Stephen Colbert of "The Colbert Report" will be taking over Letterman's "Late Show" next year. Colbert expressed his gratitude and appreciation in an article in USA Today. According to him, one of the biggest highlights of his career was being a guest on Letterman's show, and following in his idol's footsteps would be an honor.
