Watch Conan O'Brien slam Jay Leno on his final night hosting 'The Tonight Show' [VIDEO]

Jay Leno's final episode as host of The Tonight Show with Jay Leno aired last night, February 6, but who really had the last laugh? Though his ratings soared in his farewell week, his competitors and his successor had the chance to poke fun at the host. Maybe the most anticipated comment came from Conan O'Brien, who has a bit of a messed up history with Jay. Though O'Brien handled the situation well, he definitely slammed Leno in his monologue last night

"The Olympics start airing tonight on NBC. It's very cool," he said, with a smirk forming on his face. "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 then added: "I allowed myself one, but it was a good one."

O'Brien wasn't the only one to joke about Jay's departure from The Tonight Show, though. Both David Letterman and Jay's successor, Jimmy Fallon, poked fun at Leno on his final night as host.

"Congratulations on a wonderful run, and I'll tell you something -- If I was Jay Leno and I was retiring? You know what I would do? I'd go out and buy myself a car," Letterman, Jay's longtime late night rival, said.

"To Jay, we say thank you very much. He's been a great guy. We're going to miss him," Fallon said during his final Late Night monologue Thursday, before joking: "The ratings have been so good this last week because it's his last week that NBC is going to extend his week - so we're going to have another week of saying goodbye to Jay Leno."
