When he wasn't peppering Carlos Gerena with punches, Floyd Mayweather was looking at a few fighters ringside to see how they enjoyed his performance.
Mike Tyson seemed impressed, as did Roy Jones Jr.
Felix Trinidad might have been, but he may have known what was coming and left just before the fight.
Had Trinidad stayed, he would have seen Gerena take the beating of his life.
"I want to show the world that along with Oscar de la Hoya and Roy Jones Jr., I'm the best fighter in the world," said Mayweather, who defended his WBC super featherweight title for the fourth time Saturday night.
Mayweather showed off his spectacular boxing skills for seven rounds, giving Gerena such a beating that the ringside doctor finally had to step in to rescue the challenger from further punishment.
In other boxing news, supermiddleweight Randie Carver underwent brain surgery Sunday night at North Kansas City Hospital after suffering a major head injury during his fight at Harrah's Casino. No further information was released.
Carver, 25, who was repeatedly head butted in the early rounds, was rushed to the hospital after he collapsed in the 10th round of his scheduled 12-round North American Boxing Federation title fight with Kabary Salem.
