Logan Paul's attempt to get inside Anthony Joshua's head backfired spectacularly at Miami's Kaseya Center.
The WWE star tried playing mind games with the British heavyweight just before the fifth round, taunting him from ringside.
"It's good, bro. You're the old guy now. That's crazy," Logan said.
"So what are you gonna do? What are you gonna do? You've lost every single one of them. You've lost every single round. This could be a legacy ender, AJ."

It was clearly performative stuff, with Logan glancing at cameras while delivering his trash talk.
But the psychological warfare proved utterly pointless – Joshua knocked Jake out moments later.
The 36-year-old delivered a brutal finish in the sixth round, dropping Jake for a fourth time with a clean right hand that ended the contest.
The referee mercifully waved it off as the YouTuber-turned-boxer failed to beat the count.
Joshua's devastating punch left 'The Problem Child' with a double broken jaw, requiring an immediate trip to hospital.
The American was completely outclassed throughout, managing to land just 16 of his 56 punches in what turned out to be a thoroughly one-sided affair.

In reality, Joshua had likely won every single round – the complete opposite of what Logan had claimed moments earlier.
The opening rounds had been a frustrating watch for fans at the Kaseya Center.
Jake spent much of the early contest in survival mode, sticking out his tongue and simply running away rather than engaging with Joshua.
Every time the Brit got close, the 28-year-old would clinch and fall, prompting some spectators to question whether the bout was fixed given the £140 million purse split equally between the fighters.
But everything changed in the fifth round when Joshua upped the intensity.
He finally cornered an exhausted Jake and floored him with a left hook that buckled his knees and sent him crashing to the canvas.
Logan's troublemaking didn't stop when the referee called time on the fight.

He got into a confrontation with Joshua's team afterwards, attempting to grab AJ's Polymarket chain – reportedly worth around £370,000 – before security stepped in to break things up.
Jake, meanwhile, was far more gracious despite his injuries.
"I'm feeling good, that was fun, I gave it my all, I had a blast," he said before heading to hospital. "Anthony's a great fighter, and I got my a** beat, but that's what this sport is all about."
