WARNING: If you suffer from seizures or the Harlem Shake fever, you might want to stand back and start dancing.

YouTube culture appears to have been rejuvenated by the Harlem Shake videos taking over the internet. It seems every day we're finding new footage of someone doing their version of the Shake -- from firemen to grandmothers. And now, thanks to YouTube's Ryan Sims, we can watch 49 shake videos AT ONCE. Yes, 49. And yes, at once!

Watching all of these people shake their moneymakers as if their lives depended on it is making us wonder: 1) how many more 'Harlem Shake' videos can the internet handle? and 2) how can we get in on this?
