Psy cracked up the press conference with his 'horse-riding' dance.

On September 25, Psy returned to Korea and attended his press conference.

During the press conference, he talked about his busy 3 weeks in the U.S.

At the end of the conference, he stated, "It wouldn't be fun if I didn't dance the 'horse-riding' dance. Don't turn on any music though. This dance is funnier with no music."

Psy continued to dance until he left the room. The crowd burst into laughter at his funny exit.

Psy has ranked number 11 on the U.S. Billboard Single Main Chart 'HOT 100'.
