Watch 80k Koreans do it Gangnam Style

This is insane. Viral phenomenon Psy recently took to the stage in front of Seoul City Hall to give his fans a free show to thank them for their support.

What happened is what should be expected when you cram 80 000 adoring fans into a square and man is it awesome. Scary but awesome.

If you’re still unsure who Psy is (did you suddenly just discover the internet?), this should give you an illustration of what 360-million odd views on YouTube can do for someone.
