Think of them as YouTube, and the foam as views, except they would be buried in foam.

Remember when we thought the world's computer systems would collapse because of the Y2K bug, and planes would fall out of the sky? Congrats, you're a decrepit old person, but it should help you understand how Psy almost melted YouTube's ability to count views. PSY's video surpassed the mind-bending maximum view-count number the folks at YouTube assumed they would never see: 2,147,483,647.

The irony of news about something being seen so much being posted on Google+...

Two billion, one hundred forty-seven million, four hundred and eighty-three thousand, six hundred and forty seven views. Well, more now.
