Damon is mixing to great causes in his video but...pouring toilet water on your head?  Yikes!

Full disclosure...Matt Damon and I are best friends.  OK...we've never met.  But we should be best friends.  Good Will Hunting is my favorite movie.  How do you like them apples?

That being said.  Matt Damon does a lot of work for causes that are important to him.  One of those causes happens to be bringing clean drinking water to everyone in the world.  He co-founded the charity organization water.org.

So, for ALS Ice Bucket Challenge he chose NOT to waste perfectly good drinking water to dump on his head.  Instead, this happened!  What is the craziest Ice Bucket Challenge you've seen?
