One of the largest arguments against the #IceBucketChallenge is the obvious waste of water.
Matt Damon agreed, so when he was finally able to complete the deed after being challenged by Ben Affleck and Jimmy Kimmel, Damon decided to dump old water from various toilets on his head instead.
Wasting water is a personal issue to Damon, who co-founded Water.org, a nonprofit that provides safe water and sanitation to those in need.
