Matt Damon, founder of a charity that helps provide clean water for people in developing countries, took the ALS Ice Bucket Challenge using water from his toilet.

Matt Damon's philosophy is that America's toilets are cleaner than what most children drink in poor countries.  And because of the current drought in California, Damon decided to use water from his toilet for the challenge.

He challenged George Clooney, Bono, and Tom Brady.
