The veteran former talk show host also mentioned that he is "looking for interesting guests" for his forthcoming Netflix project.

David Letterman made his return to late-night television on Jimmy Kimmel Live! Tuesday (Oct. 17) to discuss the unusual gift he gave Conan O'Brien. Kicking off day two of the show's "Brooklyn Week," the retired talk show veteran of more than 30 years was greeted with a standing ovation from the audience, and joked right off the bat that "it was just good to get out of the house" and to "see famous people again."

He explained that when he was "either fired, or retired," (a running gag throughout his appearance) he wanted to spread the love to all the late-night talk show hosts — "even Jimmy Fallon," he joked — by sending them gifts. As Conan O'Brien revealed on The Late Show with Stephen Colbert on Friday (Oct. 13), he sent O'Brien a horse named, of course, Dave.

He explained the thought behind the unique gift. "The idea will be that he'll have the horse and the horse will take a dump on the show and it will be hilarious," he said. "So two or three days later I realize that things have gone terribly wrong," Letterman said, explaining that he received a "lovely" letter from O'Brien saying that his wife loves the horse and will keep it. "So now I'm screwed because I was counting on him returning the horse and I would get my money back," the former host joked.

He said he ultimately forgot the incident until O'Brien's Late Show appearance the other day. Poking fun at O'Brien's demeanor during the show, Letterman joked, "Now it's like he's losing his mind." He continued, "From what I infer, Conan will not shut up about the horse, and something happened and the horse went crazy, maybe from being around Conan all day." Letterman said his ultimate takeaway is that "no good deed goes unpunished." To which Kimmel suggested, "When in doubt, an Edible Arrangement is a good gift."

Letterman also talked about his new Netflix talk show. He wouldn't divulge details — including if the show will have a studio audience or what the title will be — but did say, "We're looking for interesting guests," and threw Howard Stern's name into the mix as a possibility. The former host also poked fun at himelf and his long beard, saying that the logline for tonight's episode will read "tonight Jimmy talks to an aging vagrant." He also reminisced on his television days. When asked if he misses it, he replied, "Some parts... no I don't. I miss wearing makeup."

Now that he's retired, he said he feels like a different person. "The great struggle in life is to be better each and every day. And if you take a look around the horizon of humanity, my god, is there anything we can do, big or small, to make the life of just one person a little bit better?" he said.

On Monday night's show, Kimmel kicked off "Brooklyn Week," paying homage to the town in which he was born by broadcasting live from the Brooklyn Academy of Music. To make the week more special, Kimmel enlisted help from Paul Shaffer, the former Late Show musical director and “kick at David Letterman’s side” for 33 years. In his opening monologue on Tuesday, Kimmel joked that Schaffer was the reason Letterman agreed to do the show on Tuesday. "We kidnapped Paul and said 'you’d better show up,'" Kimmel said.
