Demoted NBC Anchorman is putting his tail between his legs and headed back to the MSNBC dumping ground.

But, it is doubtful that he will be greeted with open arms.

Page Six says that staffers there haven’t forgotten a scathing report he arrogantly aired on his short-lived “Rock Center” about “corrosive” cable news blowhards at MSNBC, Fox News and CNN.

The two-part September 2012 report was so unpopular at MSNBC that, at a network holiday party shortly after, some over-served staffers even chanted “f uc k Brian Williams.”

“Rock Center” aired a two-parter on cable news’ “partisan ranting” from correspondent Ted Koppel. Williams introduced one segment by describing cable as, per Koppel, “corrosive and does nothing to help compromise in this country.”

Williams stuffily wondered, “Has any of this splashed up against what we do?” Koppel responded: “What works about cable television is it’s cheap and it makes a ton of money. There is nothing cheaper than a bunch of talking heads. The people who hire those talking heads have discovered the more irascible, the more partisan, the nastier they are, the bigger an audience.”

Welcome to MSNBC Brian....sounds like they are really happy you're coming back.

Not.
