World’s Largest Human Domino Topple [VIDEO]

I want to know why I never know when this stuff is happening!  How fun does this look?  It's the world's largest human domino topple according to Guiness' Book of World Records.  It consists of 850 people strapped to mattress falling on their backs.

The coolest part about this isn't even the world record.  The coolest thing is that the mattresses were eventually donated to charity after it was all over!  **Warning**  There's a really obnoxious guy commentating.
