All the people in Korea are cheering me like I'm a gold medalist or something, so I have a responsibility to my country.

It's tiring to be asked the same questions all day long: 'What is Gangnam style?' and 'Teach me how to dance.'

I will bring more Korean dance moves and Korean songs overseas.

When I signed with Scooter Braun and I decided to go overseas to promote my song, the only concern was how should I communicate with the public and the audience with my language. Scooter and I talked a lot about that: should we translate or not? Finally we didn't, and I think that was a really good decision.

I've got to wear sunglasses everywhere, all the time, even if its indoors or at night time, to be recognized. That's part of my job. I cannot take off my sunglasses. For me, staying in the United States was so dark because I can't take them off.

I've always tried to come up with funny dancing since I was young, to attract girls' attention for one thing. It's got to be funny. I can't pull it off with serious dances. That's not me.

The world's most famous and popular language is music.
