In honor of Jay Leno’s last night as the host of The Tonight Show, his rival late night hosts joked about the comedian in their opening monologues, including scorned host Conan O’Brien.

Conan O'Brien Mocks Jay Leno Goodbye

“The Olympics start airing tonight on NBC. It’s very cool. That’s right, NBC has the Olympics. It’s a big deal. NBC will finally get to show somebody who is ok with passing the torch,” O’Brien joked in his monologue on Conan.

The audience roared with laughter.

“I allowed myself one, but it was a good one,” O’Brien added gleefully.

The joke, of course, is a reference to 2009-2010 when Leno passed on The Tonight Show to O’Brien for little more than a month before reclaiming the 11:30 p.m. time slot, essentially bumping O’Brien out of The Tonight Show. The messy transition caused O’Brien to resign from NBC completely and got the attention of other late night comics, mainly Jimmy Kimmel, who held nothing back when joking at Leno’s expense.

After O’Brien left The Tonight Show, saying he did not want to contribute to the show’s “destruction,” he has refrained from bashing Leno on his TBS show ever since the “Late Night War” of 2010 ended.

Late Night Hosts Say Goodbye To Jay Leno

Other late night hosts also wished Leno a fond farewell on their shows. Jimmy Fallon, who is scheduled to take over The Tonight Show from Leno starting Monday, Feb. 17, thanked Leno in his Late Night opening monologue, saying, “To Jay, we say thank you very much. He’s been a great guy. We’re going to miss him.”

Even Kimmel himself managed to put the Late Night feud aside and congratulate Leno on his 22-year run as Tonight Show host and tweeted his congratulations.

Issues aside, 20 years at #1 is a remarkable achievement. Congratulations and best wishes to @jayleno on an incredible run

— Jimmy Kimmel (@jimmykimmel) February 6, 2014

The Tonight Show with Jimmy Fallon will premiere Monday, Feb. 17 at 11:35 p.m. on NBC after the Winter Olympics have ended. Conan airs weeknights at 11 p.m. on TBS.
