With a lot of turmoil happened over the last few weeks on Conan’s accouncement over his network NBC, Conan O’Brien has finally inked a deal to leave NBC, with a network announcement expected later this morning.

The deal paves the way for Jay Leno’s return to the 11:35 p.m. time-slot and comes hours after O’Brien all but declared on his show that this week would be his last as host of “Tonight,” a job he was promised six years ago and took over from Leno in June.

Conan O’Brien kicked off his show by joking about career options and then hammered his bosses as he has for nearly two weeks straight.

“Hello, I’m Conan O’Brien — sorry if I’m a little late,” O’Brien said. “I had a job interview at Lady Foot Locker.

“Over the past week, ratings for the ‘Tonight Show’ are up by 50 percent,” he added. “When NBC executives heard this they told me, ‘See, you really don’t fit in around here.’”

O’Brien said as long as he remains at NBC he’ll do whatever he wants and the network “has to pay for it.”

“For the rest of the week we’re going to introduce comedy bits that aren’t so much funny as they are crazy expensive,” he said.

One example: a blue Bugatti Veyron sports car (“the most expensive car in the world,” O’Brien quipped) outfitted with whiskers to look like a mouse and accompanied on the air by the Rolling Stones’ original master recording of “Satisfaction.”

Since O’Brien has only been on the job for 7 months and less than the gestation period for a baby, he could only introduce his pseudo child, his Bugatti Veyron mouse/ hamster.

Total price tag for the character: $1.5 million

“Does (the music) add anything at all to this comedy bit?” O’Brien asked while standing next to the “mouse.”

“No it doesn’t. Is it crazy expensive to play on the air, not to mention the rights to re-air this clip on the Internet? Hell yes.”
