If you’re incautious enough to spend any period of time looking at online gambling forums, two things will probably occur. Firstly, your faith in humanity will quickly disappear, and secondly, you’ll be amazed by how gullible people can be. Any online claim of extraordinary betting prowess will immediately be met with the challenge “pics or it didn’t happen,” but if you add a photo of a betting slip, the natural skepticism of the Internet’s gamblers will disappear immediately. Have these people never heard of Photoshop? However, there’s one gambler who never needs to be prompted to post a photo of his winning bets, and his bankroll is so huge that there’s no reason to suspect foul play: I refer, of course, to boxing’s undefeated quintuple world champion, Floyd “Money” Mayweather Jr.

Mayweather is famous for his enormous bets, largely because he’s been tirelessly promoting himself on Twitter as boxing’s answer to Nick the Greek. By my count, between August 2010 (when he began tweeting his slips) and February 2012, Mayweather tweeted photographs of 46 betting slips, totaling $3,890,833 worth of bets, and every single one of them was a winner, netting the fighter a cool $3,938,722 (and 87 cents) in winnings on those bets. Losing betting slips have been conspicuous by their absence. When asked about his losing slips, Floyd responded, “Why would I ever show a losing ticket when I’m 41-0.”
