It's been a while since a dance craze has so entranced the world the way that PSY's "Gangnam Style" did this year, as everyone from musicians to athletes to politicians got in on the K-Pop rapper's invisible-horse game. Just how many famous people got caught up in "Gangnam" fever? Well, here is a list of all of them*, just to show you—when the Secretary-General of the UN is biting your moves, you know you've got a dance pandemic.

And, if you're a fan of "Gangnam Style," you can vote for it in our Greatest Song of 2012 tournament!

*We undoubtedly missed some. If you know one we left out, let us know!
