ABC/"Jimmy Kimmel Live!"
In honor of Letterman's final show airing Wednesday night, Kimmel took the opportunity to address his idol's departure during his Tuesday night monologue.
Usually full of jokes, Kimmel got serious as began to explain what Letterman means to him.
"I wanted to be an artist when I was a kid, I loved to draw. And every night after my parents went to bed, I would sit at my desk in my room and I would draw until it was very late," Kimmel explained. "And while I was doing that, I would watch a television show that is very important to me, it was called 'Late Night with David Letterman.'"

"I watched the show every night and little did I know that many years and many pounds later that watching the show was a great education for me," Kimmel explained while getting emotional.

"Dave is the best and you should see him," Kimmel said while tearing up.

Kimmel then explained that he wanted to show his audience "one of my favorite segments of the show," which was "a parody of the after school specials they would run in the 70s and 80s."
Kimmel then ran an old "Late Night" clip in which Letterman very ironically comforts a little boy named Jimmy about the end of the show.
"Jimmy, I've been looking all over for you," Letterman says in the old video bit. "I know how you feel, hurt at first, but believe me, you're going to get over it. Jimmy, just because the show is canceled doesn't mean it goes away forever. It can live on through re-runs and syndication."

The irony was not lost on Kimmel, who told his audience, "I think this sums up how I feel this week, almost supernaturally well."
