Most of us are probably spending our New Year's Eve lounging around the house pretending it's still Christmas, before starting on the ciders at about 4pm. The rest will be a blur, no doubt.
Not Floyd Mayweather, though - as he's got a few million to make in a nine-minute fight against young Tenshin Nasukawa.
The New Year's Eve action will see the 41-year-old come out of retirement to fight the kick-boxing prodigy in an exhibition match at Saitama Super Arena in Japan. The match will consist of three, three-minute rounds.
"People in Japan, listen. I will take down Mayweather," Nasukawa said ahead of the fight.
"You should look forward to it."
Meanwhile, Mayweather promised to 'entertain' when speaking to press at a news conference.
While we're yet to see who'll come out triumphant (Mayweather's reportedly not shown up yet, according to Twitter), one thing we do know is know is how much Mayweather is set to earn.

Turns out he'll be raking in some serious cash for his bout against Nasukawa. Seriously serious cash.
We're talking $9 million (£7 million), if we're to believe his latest Instagram post, which was captioned: "What if I told you I was making $9,000,000 for 9 minutes of sparring in Tokyo Japan would you do the same if you were me? I like to call it a 9 minute walk thru."

Not bad. Works out at about £13,000 a second according to our terrible maths.
With various commercial add-ons, it could amount to around $69m for the fight as a whole.
Mind you, that's a drop in the ocean compared to how much he reportedly earned for his fight last year with Irish star Conor McGregor.
Mayweather beat McGregor in August 2017 in 10 rounds, and apparently it had been worth showing up to work that day, as he made a reported $300m.
Against Manny Pacquiao in 2015, he also reportedly pocketed a pretty tasty $100m - though it's believed he actually walked away with nearly $150m
Guess they don't call him Floyd 'Money' Mayweather for nothing...
