We are just at the studio, me and my choreographers, we are spending like 30 nights and we are thinking, what is my next dance move? Because in Korea there are huge expectations about my dancing. So it was a lot of pressure.

I'm not that good looking. That's why 'Gangnam Style' works. If someone handsome uses that phrase it's just awkward. But if someone like me uses it, it's funny.

My lifetime role model and hero is Freddie Mercury of Queen.

I never expect I would become a K-pop star.

I just made my album. I did my best, and I uploaded the video just at YouTube. That was all.

My wife looks at the person Park Jae Sang and the singer who goes up on stage, Psy, as different people.

If I say, 'Hey, I'm Psy.' 'Psy?' 'The guy from the video on YouTube?' 'Oh.' I hate that. I've got to be more popular than the video. So I need to keep promoting myself.
