Is this why Jay Leno was involuntarily retired by NBC?

Is this why Jay Leno was involuntarily retired by NBC?  A collection of his one-liners that just may have contributed to the network's decision, via reader Simi L.:

"I was going to start off tonight with an Obama joke, but I don't want to get audited by the IRS."

On NSA surveillance: "We wanted a president who listens to all Americans - now we have one."

On a new IRS commissioner: "He's called 'acting commissioner' because he has to act like the scandal doesn't involve the White House."

On closing the Guantanamo prison for terrorists: "If he really wants to close it, turn it into a government-funded solar power company. The doors will be shut in a month."

Concerning the Benghazi, Associated Press, and IRS scandals: "Remember in the old days when President Obama's biggest embarrassment was Joe Biden?"

On Obama saying he didn't know about the IRS scandal: "He was too busy not knowing anything about Benghazi to not know anything about the IRS."

"The White House has a new slogan about Benghazi : Hope and change the subject."

"It's casual Friday, which means that at the White House, they're casually going through everybody's phone calls and records."

"It is not looking good for President Obama. Today his teleprompter took the fifth."

"Fox News has changed its slogan from 'Fair and Balanced' to 'See, I told you so!'"

On Obama's commencement address: "He told the young graduates their future is bright unless, of course, they want jobs."

On a Chicago man who set a record for riding a Ferris wheel: "The only other way to go around and around in a circle that many times is to read the official report on Benghazi."

On White House claims of ignorance on the scandals: "They took 'Don't Ask, Don't Tell' out of the Pentagon and moved it into the White House."

"These White House scandals are not going away anytime soon. It's gotten so bad that People in Kenya are now saying he's 100 percent American."

One can easily imagine a petulant That One phoning Steve Burke: “Dude, stifle that Leno guy, would you?”
