It was nice to Floyd Mayweather smiling for once.

Fans have become too accustomed to seeing the boxing great, angry and ranting about his plight and a lack of respect during HBO's 24/7 series. Mayweather made an appearance last night on TBS's "Conan." It was all giggles and grins.

Conan tried to throw Mayweather off his game by posing a awkward boxing threat. Mayweather said his kids and Victor Ortiz have something in common, the both love the Harry Potter films. Floyd also said he learned a good lesson when he worked with the WWE. Mayweather knows pro wrestling isn't always fake. He admitted that actually broke the "Big Show's" nose with a punch.
