Conor McGregor and Nate Diaz's rivalry hit boiling point during a trash-talking segment on live TV as the 'Stockton Slugger' stormed out of the interview.
The two UFC stars appeared via satellite on CNBC in the build-up to their blockbuster clash at UFC 196 in 2016.
And McGregor was clearly in his element as he continued to taunt the 34-year-old Diaz over money and counting to 10.
The 31-year-old Irish MMA superstar bragged about making more than $10m from the fight and said his opponent 'owed' him for walking away with a hefty pay package.
"He can thank me for that one," McGregor said.
"I've made more millionaires in this game than anybody else."
McGregor refused to let up his relentless attack on the Stockton native as he mocked Diaz for earning over $40,000 from his last fight.
"I tip with that money," the 'Notorious' told Diaz.
Diaz started to lose his cool with interviewer Jane Wells and McGregor as the theme of money continued to remain the dominant topic of the interview.
"What is this, the money channel?" he asked.
While McGregor flirted with Wells and told her to send him a photo, Diaz initially tried to unclip his microphone before pausing for a moment.
But when Wells broke into laughter and tried to put the interview back on track, the 'Stockton Slugger' had enough and he unclipped his mic, took off his earpiece and walked out.
McGregor, who was told that Diaz had walked off, remained for the rest of the interview and reassured the host that fans wanted the fight.
Wells wrote for CNBC that she was shocked Diaz walked out of the interview, saying that in "more than 30 years in the business, that has never happened to me."
Diaz would have the last laugh as he shocked the MMA world after beating McGregor by submission in Las Vegas.
But the 'Notorious,' who is preparing for his UFC comeback in 2020, would avenge his defeat in their 2016 rematch.
