As best as we can ascertain, the requisite elements for a "Harlem Shake" video are as follows:
- Conspicuously dressed individual begins dancing to song intro while others pay him/her no mind
- At the approximate moment when the bass line mmmmmmm drops, scene becomes a raucous dance party; the more colorful and arbitrary the attire and props, the better
- This spirited, spontaneous Halloween party of sorts continues for several seconds, until the video concludes
That's about it. Also, there should be a cat.
