It's been done millions of times online. You've seen it in your Facebook feeds, on websites...everywhere.

Did you ever wonder how, where, or why it all began?

What's the story behind the Ice Bucket Challenge?  This video will show you the effects of ALS, and the man behind the viral sensation to help bring awareness -- and a cure -- to Lou Gehrig's Disease.

The video will break your heart...but it's so worth the watch. Inspiration, to say the least.

Bravo, Pete Frates.
