Parting Question: Leno Vs. Conan

Conan O’Brien makes his debut as the host of NBC’s “The Tonight Show” in Universal City, Calif., in June.

Sources connected to Conan O’Brien tell TMZ NBC honcho Jeff Zucker has been “nasty, arrogant and threatening” in negotiating Conan’s out. The Conan people are outraged, saying the blame for the Jay Leno /’ConanO’Brien/”Tonight Show” debacle falls squarely at Zucker’s doorstep.

An NBC spokesperson tells TMZ, as for claims Zucker has been nasty, arrogant and threatening, “There is absolutely no truth to that. It is easy to make false statements under the cloak of anonymity.”

We’re told Conan is so pissed off at NBC, he told the network he was leaving even though he still doesn’t have a place to go — at least not yet. Sources say Fox still has not made an offer.

Personally, I think Leno has had his shot and should back out gracefully. What say you? Leno or Conan?
