Michael Phelps took another world record on Saturday when he become the first person to ever finish the 100-meter butterfly in less than 50 seconds.

“I felt so good coming off the wall,” Phelps said. “My kick off the wall felt really, really good. I saw the splash out of my left eye from his lane coming over, and I saw him getting closer and closer, and I heard the crowd getting louder and louder.”

Phelps’ rival Milorad Cavic also finished the race in under 50 seconds, but he was still .13 seconds behind the champ.

“We face each other, but I don’t look that way. I look up in the crowd,” Phelps said. Still, “it’s literally like a straight showdown. It’s like boxers coming face to face for a weigh in. I think that’s kind of cool for the sport.”

Just hours after the event Phelps was seen celebrating with 2 joints and a beer.
