Floyd Mayweather Jr.
Floyd Mayweather Jr.’s supreme cockiness is enough for reality show gold, and his public persona is absolutely stranger than fiction. Now that he’s away from the ring, the Michigan native has more time to spend on his $1,000 haircuts and his boxing ring in Las Vegas, among other insane pursuits. Throw in some of his biggest rivals in the mix, including Manny Pacquiao, and you can just watch social media blow up.
