Floyd Mayweather's 62 years old dad rocks the stage

Just like his world champion son, Floyd Mayweather Sr. was spotted at a party in Las Vegas barely 48 hours to his son's historic fight with Manny Pacquiao.

Interesting, the 62-years old Mayweather fell flat on his butt while displaying some of his dancing skills at the Fiesta Rancho Casino in Las Vegas on Thursday, April 30, 2015.

In a video released by TMZ Sports, Mayweather Sr. got up onstage and was doing his best James Brown impression to the delight of crowd when he lost his footing and crashed down to the floor only to be helped by members of the performers.
