Jay's turn.

In another wacky twist in NBC's late night drama, Jay Leno opened up his show Monday night explaining how one of the great tumults in TV history got so tumultuous, and how it's going to end up. His surprising answer: He's not sure.

"I thought maybe I should address this [and] give you my view of what has been going on here at NBC," he told surprised audience members, adding, "It looks like we might be back at 11:30, I'm not sure. I don't know. I don't know."

He also defended "The Tonight Show's" Conan O'Brien, "I have no animosity towards him. This is all business. If you don't get the ratings, they take you off the air."

A "Tonight Show" succession announcement - with Leno back at 11:35 - is in fact expected Tuesday morning, with Leno replacing a guy who spent six years waiting for a job he held for only about seven months.

Monday night, Leno's soliloquy/monologue began with some history: "Let's start in 2004," when he was told O'Brien had " 'gotten other offers,' and that they didn't want him to go."

I said, " 'Well, I've been number one for 12 years.' They said, 'We know that, but we don't think you can sustain that.' I said, 'OK. How about until I fall to number two, then you fire me?' 'No, we made this decision' " - to replace him on "Tonight."

He told them 10 p.m. "will never work." "But they persisted: 'We want to put you on at 10. . . . Didn't seem like a good idea at the time. I said, 'All right, can I keep my staff?' There are 175 people that work here. 'Yes, you can.' "

He didn't like the idea of a half-hour show at 11:35 either, but when O'Brien rejected the offer of a move to midnight, Leno said, " 'Yeah, I'll take the show back. If that's what he wants to do. This way, we keep our people working, fine.' So that's pretty much where we are."

Damage control on Leno's part? Sure. But plenty of work ahead, too.
