American radio host Alex Jones has turned heads before with claims that the US government was behind the Oklahoma City bombing and the September 11 attacks.
But none of that quite prepared British host Piers Morgan for what would happen when Jones appeared on his CNN show.
Jones created a petition to the White House to deport Morgan for favouring strict gun-control laws. More than 100,000 people have signed so far.
But when Morgan asked him why he should be deported, Jones launched into a furious tirade that included Hitler, the New Delhi rape case, and "suicide mass murder pills."
"The government buys 1.6 million bullets; armoured vehicles; tanks; helicopters; predator drones armed, now in US skies, being used to arrest people in North Dakota," Jones told Morgan.
"The Second Amendment isn't there for duck hunting. It's there to protect us from tyrannical government."
From there, Jones became downright unhinged: "I'm here to tell you, 1776 will commence again if you try to take our firearms!" he said angrily. "Doesn't matter how many lemmings you get out there on the street, begging for 'em to have their guns taken. We will not relinquish them. Do you understand?"
The White House said it would respond to Jones' petition because it had garnered so much support, adding that "freedom of expression is a bedrock principle in our democracy."
The interview went viral online, with Jones trending on Twitter today. Most of the discussion though was to make fun of the radio host.
The stoush came as US gun control advocates, led by gun massacre survivor and former congresswoman Gabrielle Giffords, started a co-ordinated attack on the powerful gun rights lobby.
Giffords, the former congresswoman who was shot in the head in the mass shooting that killed six in Tucson, Arizona two years ago, has used the anniversary of that attack to launch a new gun control group, Americans for Responsible Solutions.
