Logan Paul was shocked when he learned how much his brother, Jake, charged fans to watch his win over Mike Perry.
The younger Paul sibling fought and defeated Perry with a brutal KO to pick up his tenth professional win in the boxing ring.
Paul thanked McGregor for 'purchasing' his showdown with Perry
He sat down with his sibling Logan to assess his performance, and his next showdown with heavyweight legend Mike Tyson on November 15.
And 'The Maverick', 29, was stunned to discover 27-year-old Jake's showdown cost $64.99 for US customers to purchase.
He said: "Conor McGregor is your biggest fan, he definitely watched it live then hopped on to X.
Paul then responded: "Thanks for the 65 bucks [dollars].
This left his brother was stunned, as he asked: "Dude, your pay-per-views are $65 now? Man, that's crazy.
"That's so cool, man. Wow."
The conversation then turned to UFC superstar McGregor's tirade on social media, as he fired Perry from his newly acquired bare-knuckle promotion BKFC.
Logan added: "That was a common Conor McGregor L to fire him. He's a broken man," though regardless of the attack on his younger brother, he still likes McGregor. "He is still entertaining," he added.
"Also his bank account still, wow."
McGregor, whose net worth runs into the hundreds of millions, ripped into Paul after the showdown, with the pair going back and forth via social media for a second time.
The 'Problem Child' has always attempted to entice the Irishman back into the boxing ring, for the second time since his 2017 defeat to Floyd Mayweather.
But the fight is highly unlikely, with Paul and McGregor streets apart in terms of weight while the latter still is under contract with the UFC.
Paul took aim at 'The Notoroious' at his post-fight press conference, insisting he was 'running' from a showdown.
He said: "Conor McGregor can say what he wants, but he won't fight me either.
"So I knocked out Mike Perry, Conor McGregor, let's run it, but you won't do it because you know what's gonna happen.
"You know what I did to Nate Diaz, who you went toe-to-toe with. So Conor McGregor, get in the gym and start winning fights.
"And then maybe we can have a conversation."
The win took his boxing record to 10-1, with his solitary loss coming against Tommy Fury. Other notable wins have seen him knock out former UFC welterweight champion Tyron Woodley and beat MMA legends Nate Diaz and Anderson Silva.
Tyson, though, remains his biggest opponent despite the huge age gap.
And the legendary former heavyweight world champion has already begun the countdown to November.
He tweeted after Paul's victory over Perry: "Countdown begins.
"118 days. 16 weeks and 6 days. 17 weekends. 2,832 hours. 169,920 minutes. 10,195,200 seconds
"Clock Starts Now. #TysonPaul #TheClockIsTicking #JakesWake."
