Video: Floyd Mayweather appears on Conan

Floyd Mayweather appeared on Conan O'Brien's late-night talk show Monday in advance of Saturday's fight with Victor Ortiz in Las Vegas. Mayweather talked about the Ortiz fight ("I never worry!"), his pro wrestling experience and driving Segways through his expansive Las Vegas mansion.

Mayweather was mostly respectful of his upcoming opponent, save for one exchange when Conan said he was surprised to hear Ortiz was a Harry Potter fan.

"My children are huge Harry Potter fans, they got something in common!" Mayweather said, prompting laughter from the studio audience.

Near the end of the interview, Conan asked Mayweather about Manny Pacquiao and the possibility of a Mayweather-Pacquiao megafight coming off:

Conan: “I have to ask you, it’s my job: Do you think you'll ever fight Manny Pacquiao, do you think that's going to happen?”

Floyd: “Hopefully. If you’re the best, you got to take the test. I represent the red, white, and blue. Represent the '96 Olympics. Represented this country. And I just want it to be fair, to be on an even playing field. He is from another country. All I ask is just take the test.”

Conan: “You want him to take tests for performance-enhancing drugs.”

Floyd: “Just random urine and blood tests. Which I'm doing for this fight and I do for every fight. Just to clean up the sport of boxing.”

Conan: “So if he does that, you would fight him?”

Floyd: “Absolutely.”
