Floyd Mayweather completely lost his head at Brian Kenny after he addressed the boxer as the "former" No. 1 pound-for-pound king during a live interview back in May 2009.
Mayweather went on ESPN to talk about his upcoming championship fight with Juan Manuel Marquez.
Kenny interviewed the boxer and all hell broke loose when the ESPN reporter failed to recognise him as the best fighter on the planet.
Kenny opened the interview by saying: "We welcome into SportsCenter the former No.1 pound-for-pound fighter in the world, Floyd Mayweather..."

He took offence to Kenny calling him the "former" as he hit back. Kenny argued that Mayweather's retirement forced him out of the pound-for-pound rankings.
Mayweather responded by saying he has never been beaten, then he added: "I forgot, I'm talking to Brian Kenny, a guy who's never laced up gloves a day in his life, who don't know nothing about boxing."

Kenny then mentioned Manny Pacquiao before questioning Mayweather's pay-per-view pull compared to Oscar De La Hoya.
They went on to discuss Mayweather's opponent Marquez, who was moving up two weight divisions to face the American. But he defended his choice of foe.
Kenny asked Mayweather whether he would work with Bob Arum so he could challenge Pacquiao to which he replied by saying: "We already know me, and Bob Arum have a problem, and we have an issue. So that's going to be hard to make. If Pacquiao want it, he can get it. You know that."

Kenny: "You didn't give him a chance this time."
Mayweather: "I've never ducked or dodged no opponent, so stop!"
They continued to bicker until Kenny thanked Mayweather for coming on.
