Fox News host Tucker Carlson jumps at the opportunity to stoke the temper of anyone with opposing viewpoints, but now the tables have turned.

Unaired footage of Carlson going ballistic on historian Rutger Bregman is going viral.

Strangely enough, Carlson began the interview by commending Bregman for taking wealthy attendees of the World Economic Forum in Davos to task last month for remaining silent about the world's rampant wealth inequality.

Bregman than accused Carlson and Fox News of doing the same thing and that's when things began to go off the rails.

Watch below:

"What the Murdochs basically want you to do is to scapegoat immigrants instead of talking about tax avoidance," Bregman said. "So, I'm glad you're now finally raising the issue, but that's what's been happening for the past couple of years."

When asked by Carlson how that worked, Bregman continued:

"It works by you taking their dirty money. It's as easy as that. You are a millionaire funded by billionaires...You're not part of the solution, Mr. Carlson, you're part of the problem actually...It's not very convincing to be honest."

Carlson was livid.

"I wanna say to you why don't you go f--k yourself, you tiny-brain—and I hope this gets picked up—cause you're a moron. I tried to give you a hearing, but you were too f--king annoying."

An unfazed Bregman responded simply:

"You can't handle the criticism, can you?"

Bregman had previously alluded to the video's existence earlier this month, but was unsure if they would air the footage. Instead, he shared an email screen shot of Carlson calling him an asshole.

Before the video's release, Justin Wells, the Senior Executive Producer for Tucker Carlson Tonight said of Bregman's then-unaired interview:

“Sadly, the guest turned an opportunity to have a substantive, informative discussion into an obviously calculated personal insult campaign. We were disappointed in the segment and respect our audience’s time too much to consider airing it.”

Twitter users disagreed upon the video's release: They loved it.

They weren't done either.

Most thought Bregman gave Carlson a much-needed comeuppance.

It's safe to say Bregman won't be back on Carlson's show any time soon, but the damage has already been done.
