When it comes to serving up an epic clapback, you already know that Floyd Mayweather Jr. is going to let the money talk for him.

In a possible response to T.I.'s and other people's shade towards him over recent footage of the retired, undefeated boxing champ dancing with Tip's wife, Tiny Harris, an unfazed Mayweather took to his Instagram account Monday night and tried to knock out his haters by posting a $100 million check.

He called his haters "backseat drivers" who are "so worried about another man's legacy instead of trying to write their own."

And Mayweather was just beginning to pump his jab and warm up with this scathing clapback.

"Y'all call them watches, I call them time pieces," he added later in the post. "Y'all call them boats, I call them yachts. Y'all call them houses, I call them mansions. Y'all charter jets and we own jets." 

Good grief! Check out Mayweather's full post below.

This response follows The Shade Room posting footage of Mayweather dancing with Tiny at Mariah Carey's Halloween party.

Seeing that footage must have struck a nerve with T.I. because he posted this video Monday of Kevin Hart using "get your Mayweather father-face-ass up outta here" during a recent roast session over dinner — a dinner that the rapper attended.

Take a look.

Mayweather's $100 million check IG followed.

Of course, beef between Mayweather and Tip over Tiny isn't new.

In May 2014, the "What You Know" rhyme slinger approached Mayweather in Las Vegas over Tiny and reportedly scrapped with the boxing champ, leading to an all-out brawl and melee at Fatburger on the Vegas Strip.

Just last month, T.I. also went off on Mayweather with an explosive IG for saying "All Lives Matter."

Whose clapback hit the hardest, though?

These two might just have to shoot the fair one to settle this once and for all.
