Without saying exactly why, Donald Trump decided Wednesday to pick another fight with Fox News, announcing a boycott of the network due to its "unfair" coverage of him. That night, the network's talking heads were happy to oblige: From superstar Bill O'Reilly to an assortment of contributors, the GOP front-runner's announced boycott of Fox News was met with mockery, scorn and blue language.

"Carly [Fiorina] cut his b---s off with the precision of a surgeon, and he knows it," National Review editor Rich Lowry told Megyn Kelly on "The Kelly File."

"What did you just say?" Kelly -- a particular target of Trump's scorn -- said wide-eyed, covering her mouth. "You can't say that!"

Lowry went on to compliment Fiorina as a "tough lady" for standing up to Trump during the second GOP debate, echoing his praise of Sarah Palin in 2008, who he felt "sent little starbursts through the screen and ricocheting around the living rooms of America." Later, he continued his barrage against Trump via Twitter after Trump demanded an apology.

Meanwhile, Fox contributor Laura Ingraham, who usually gets along with the mogul-turned-candidate on her radio show, was left shaking her head on Fox anchor Bret Baier's "Special Report."

“You are running for president of the United States," she said, laughing. "You’re going to get tough questions!”

Others on the panel chimed in: “I mean, it’s just childish the way that he’s reacting," said Stephen Hayes, a columnist at the Weekly Standard famous for his book alleging a close connection between Saddam Hussein and Osama bin Laden written in the leadup to the Iraq War. "As if tough questions are somehow inappropriate for someone who’s running for president of the United States."

"I think it’s crazy," Hayes added.

Finally came O'Reilly, who was fairly understated compared to Lowry or Hayes. In an interview with Carly Fiorina, O'Reilly let off a thinly veiled jab at Trump about his recent tweets disparaging Fox News, and him in particular.

“I intend to beat Donald Trump,” Fiorina told O'Reilly. "I’m not going to engage in personal insults."

“So that means you’re not going to tweet after this interview that I’m a pinhead?” he asked.
