EW's editorial guidelines Published on June 8, 2021 01:00PM EDT Before Conan fades to black, Conan O'Brien will laugh it up one more time with Jack Black. Instead of cutting his goodbye short, he's bringing on Martin Short. And, well, we're still working on sentences involving JB Smoove, Mila Kunis, and Bill Hader. Ys, the final days of the TBS late-night talk show, which conclude June 24, will feature some of the host's most notable celebrity guests. And as you will see below, that list also includes Dana Carvey and Patton Oswalt. The last two weeks of shows will feature extra laughter (and tears) from a live audience at the Largo Theater in Los Angeles, marking the first time that O'Brien will hold comedy court in front of an audience in more than a year. These farewell shows also will boasts a few surprise guests and a look back at O'Brien — who is currently the longest-tenured late-night host on American TV — and his impressive 28-year tenure in late night. A former Simpsons writer, O'Brien succeeded David Letterman in the hosting chair of NBC's Late Night in 1993. After 16 years in that slot, he briefly hosted The Tonight Show in 2009 before beginning an 11-year run on Conan. Jack Black, Mila Kunis, and Bill Hader will be among the final guests on 'Conan'.
