First is the Dougie, then the Gangnam Style, which has more than a billion views on YouTube, and now is the growing popularity of Harlem Shake. I don't know where it came from but parodies of the dance are now very popular on the said video-sharing website.
My favorite would have to be the Miami Heat's version. Hilarious! :D
This one has my besprend on it! Lol!
If you can watch the different versions/parodies of it, you'll die laughing!
