A day rarely goes by when someone doesn't take to social media and call out a celeb they don't like, in some kind of bizarre post.
And today is no different, with China's richest man Jack Ma asking for a pop at former boxing world champion Floyd Mayweather.
In a video posted to Twitter by boxing legend and Mayweather rival Manny Pacquiao, the founder of tech firm Alibaba can be seen hitting the pads - clearly in preparation for a potential bout.
Taking a break from the workout, Manny turns to the camera and says: "Floyd Mayweather, if you want a real fight, fight me. If you want an exhibition, my guy, my friend, Jack Ma will take care of you."
Now, though Mayweather has competed in a couple of exhibition matches since he retired professionally with a perfect record of 50-0, it's unlikely that he's actually going to jump in the ring and batter China's wealthiest man.
What's more likely is that Pacquiao is looking for another go at Floyd, who beat him in 2015.
But they're not the only ones having a war of words online. Another of Mayweather's former opponents Conor McGregor also recently challenged an unorthodox opponent.
The Irishman hit out at the 'Candy shop' singer 50 Cent - who he thought he had become friends with following the promotion for the Mayweather fight last year - because of a set of memes which mocked him.
In one of the posts, Fiddy superimposed the Notorious's head onto the body of Britney Spears in a photo of her during the infamous umbrella attack.
The caption read: "Is that you Britney. LOL."
Now, never one to take this kind of thing lying down, McGregor went in on his former ally and called him out.
Explaining the story behind their beef, McGregor said: "I'd have to probably say 50 Cent, I'd like to fight him.
"Throughout the course of the Floyd Mayweather build-up I used him as a tool, a promotional tool on the free also, I knew he was linked to Floyd so I tied him in also and he responded big time and capitalised on that audience so I was very thankful."
