Floyd Mayweather was set to earn $9 million for nine-minutes work on New Year’s Eve.
In the end, though, it took the 41-year-old just 140 seconds to pocket that eye-watering figure.
Mayweather made light work of Japanese kickboxer Tenshin Nasukawa in their exhibition bout in Tokyo.
The former five-weight world champion floored his 20-year-old opponent three times inside the opening round before his team eventually threw in the towel.
Nasukawa looked hopelessly out of his depth and was in tears as the exhibition bout was brought to an end.
Some fight fans expected the rising MMA star to give Mayweather a serious run for his money after seeing clips of the youngster in action.
His speed looked particularly impressive.
However, the ageing Mayweather - who retired from boxing with a perfect professional record of 50-0 last year - made the most of his 4kg weight advantage and recorded an effortless victory.
The smile on his face and his dance after the knockout - not to mention the fact he turned up several hours late - showed this wasn’t a fight he needed to take remotely seriously in order to win.
After beating Nasukawa, Mayweather was quoted by BBC Sport as saying: "I'm still undefeated; Tenshin is still undefeated. Tenshin is a true champion and a hell of a fighter."
Addressing the Japanese fighter, he added: "Hold your head up high.
"I want the fans around the world to support Tenshin, he's a great guy and a great champion."
Nasukawa, meanwhile, has now spoken out about Mayweather and the fight via an emotional post uploaded to Instagram.
“I have worked hard with a big dream in the combat world. Karate, Kickboxing, MMA and Boxing. When I first got the offer I took it in a flash. I thought this was an opportunity of a lifetime, and although there were significant differences in accomplishments and weight classes, I felt that I must not run and take on the challenge.
“The days since the fight was confirmed have been enjoyable but with concerns, and I spent the time thinking about many things. At the end of the day, I got finished, but I have no regrets. I am disappointed at myself since I thought I could have done better. But I will face the facts and will continue to take on any challenge.
“I learned that I didn’t work hard enough to earn this opportunity, and I will use this defeat to improve myself and move forward this year. Despite all the things that happened leading up to the fight, I came to realize how truly great Mayweather was. I was the one underestimating him. I promise to make it to that level!
“It may take some time for me to become the man to haul the industry on my shoulders, but please continue to support me! Everybody who work to make this fight happen, thank you very much. Mr. Mayweather, thank you very much."
Classy stuff from the youngster, whose pride will have been hurt after suffering such a humiliating defeat.
He truly felt that he could trouble Mayweather - as did his fans - but the gulf in class between the two fighters was cataclysmic.
Still, it’s not all bad. Nasukawa will have woken up this morning for a significantly boosted bank balance, while his professional record also remains unblemished.
