I keep looking for some deeper meaning in this video, so far nothing definite comes up.
I guess one way to look at it is as a critique of collectivist culture. All Confucian influenced countries emphasize a form of conformity.
In this video, you have a contrast between a ridiculous dance performed in a large group (silly dance conformity?) and pranks pulled by a non-conforming individualist.
Then there is a theme of light misogyny with Psy pulling chairs from under women, undoing their biking tops, women being ejected into a pool, etc.
I'm also really attracted to his female sidekick; its that combination of a goofy dance with a resigned and melancholy facial expression. A good metaphor to my view of life.
Yeah, I really don't know what this post adds to the world, but... you read it anyway.
