In a recent episode of the talk show, David Letterman took a moment to read some letters from home viewers, proving once again why he is a beloved figure in the world of late-night entertainment.

The first letter came from Gene Harris in Fort Worth, Texas, who asked for recommendations on what to do in New York City. Letterman enthusiastically responded, highlighting the beauty of Autumn in the city and suggesting that they couldn't have picked a better time to visit.

Next up was a viewer from Herndon, Virginia, who jokingly asked what to do with Letterman's new CD. He playfully advised them to unwrap it and give it a listen, while also mentioning that the show's announcer, Alan Coulter, has his own CD for fans to enjoy.

A question from Bill Jones in Chicago, Illinois, asked Letterman what he does after work. In a witty reply, the talk show host revealed that he does the same thing every night after the show ends, concluding the segment by bidding farewell to the audience.

But there was a surprise in store for viewers as Letterman announced that one of his all-time favorite guests was in attendance that night. The show featured a segment called the "Off-Screen Celebrity Cameo," showcasing the surprise guest. The anticipation built as the audience eagerly awaited the reveal.

With such a star-studded lineup, including Steve Martin, Koki Roberts, and Dr. John, it's clear why Letterman considers this particular show among his favorites. The excitement continued to build as the off-screen celebrity made their appearance, thrilling both the audience and viewers at home.

Sadly, this unforgettable episode marked a significant moment for the show. In a surprise announcement, David Letterman revealed that he would be retiring from his long and successful career in late-night television. As the show came to a close, Letterman expressed his gratitude to the audience for their support over the years and bid them goodbye.

With his trademark humor, Letterman joked about the fake beer commercial they had never done in the show's 18-year history. As he bid farewell, he acknowledged the immense salary he was leaving behind and thanked the viewers for the good times.

Although it's always sad to see a beloved talk show host retire, this episode will undoubtedly be remembered as an extraordinary farewell. David Letterman has left an indelible mark on the talk show genre, and his contribution to late-night television will not be forgotten.
