If there's one thing Floyd Mayweather doesn't need right now, it's money. He had plenty of money to spare prior to his big May 2 fight against Manny Pacquiao. And during that fight, he raked in more than $200 million in PPV sales alone for 36 minutes of work. So the guy's not hard up for cash at the moment. But over the weekend, the rich got even richer.

Late last night, Mayweather revealed that, over the last few days, he has placed bets on at least four professional sporting events. Three were NBA games and one was the Gennady Golovkin/Willie Monroe Jr. fight. And after they were all said and done, Mayweather was able to walk away with almost $500,000:

That $500,000 is pretty much nothing to Mayweather. But winning this weekend did give him the opportunity to use the phrase, "I don't do anything for free." So score another victory for the champ! Outside of what happened at the Warriors/Grizzlies playoff game late last week, he's having a hell of a month.
