Conan O'Brien bids farewell to late night on final episode of 'Conan'

June 25 (UPI) -- Conan O'Brien said goodbye to late night television on the final episode of his TBS series, Conan.

The comedian discussed his career, thanked his staff, including sidekick Andy Richter, spoke to Jack Black, who was his final guest, and had an exit interview with Homer Simpson in animated form on Thursday.

"I've devoted all of my adult life, all of it, to pursuing this strange phantom intersection between smart and stupid. There's a lot of people that believe the two cannot coexist, but god I will tell you, it is something that I believe religiously. I think when smart and stupid come together, it's very difficult but if you can make it happen, I think it's the most beautiful thing in the world," O'Brien said. before Conan went off the air for the final time.

O'Brien was a writer on The Simpsons and expressed his love for Homer, after joking about wearing a wig. Homer was working for TBS and did not know who O'Brien was.

"Thank you Homer, you mean the world to me," O'Brien said. "You mean the world to me Conrad," Homer replied.

Black walked onstage with a limp and was using a cane as he arrived for his interview. The actor explained how they had planned a big musical number where he would fake an injury, however, he ended up getting injured for real while they taped the segment.

"I wanted to be the best guest of all-time for your final episode and instead I am literally the lamest guest of all time," Black said.

"It felt fitting for our show," O'Brien added.

Black then performed a cover of "My Way" by Frank Sinatra that paid homage to O'Brien.

O'Brien will be transitioning to a new, weekly variety series on HBO Max.
