Floyd Mayweather brings the pain in the boxing ring. He makes it rain in the strip club.

The undefeated welterweight dropped $100,000 on strippers in Miami’s E11even “gentlemen’s” club this weekend, according to TMZ Sports. The pugilist was joined in his philanthropic efforts of financial uplift of single moms and struggling coeds by actor Jamie Foxx and rapper P Diddy. The trio trekked to the club to celebrate DJ Irie’s birthday but ended up giving presents to everyone dressed in their birthday suits.

Mayweather, who made more than $100 million last year, fights again in September. He looked all of his 37 years in his decision victory over Marcos Maidana in May. The pay-per-view numbers declined to beneath one-million homes. But Mayweather still has three fights left on his six-fight $200 million Showtime contract.

Mayweather reportedly hauled the $100,000–one-tenth of one percent of his 2013 income–into the club in a backpack. Who brings a backpack to a strip joint?
