Jay Leno continues biting the hand that feeds him

How much crap should a network put up with from one of its employees?

Every day now Jay Leno pushes closer and closer to pushing NBC to its breaking point. Undoubtingly the report that leaked that says the network is preparing for life without the "comedian" and intends to replace him with Jimmy Fallon. However, that replacement is tentatively scheduled to begin sometime next year.

Last night in his monologue, Leno continued his "lighthearted" jabs, which have already angered the network's entertainment chief Robert Greenblatt.

"Did you hear about this? A 28-year-old woman from Serbia has a rare brain condition where she sees everything upside down," Leno said in Tuesday night's monologue. "The good news? She's now been given a job at the White House as President Obama's economic adviser. Isn't that crazy? It's unbelievable. She sees everything upside down. In fact, she thinks NBC is at the top of the ratings." Har, har.

The day before, Leno called NBC executives snakes.

"You know the whole legend of St. Patrick, right?" he joked. "St. Patrick drove all the snakes out of Ireland -- and then they came to the United States and became NBC executives. It's a fascinating story."

It is not new for late-night hosts to josh with their networks, but you would think an executive asking you to stop would not lead to you doing it every night.
