If you've ever been given a swirly, take heart: Matt Damon's had toilet water all over his head, too!
The Oscar winner chose this fate, though, in response to Ben Affleck and Jimmy Kimmel nominating him for the ALS Ice Bucket Challenge! But why did Matt pour cold toilet water all over himself—as opposed to just dousing himself with cold water from the tap?
The challenge, he said, "posed kind of a problem for me, not only because there's a drought here in California, but also because I co-founded Water.org." Because "not everybody has access to a clean drink of water—there are about 800 million people in the world who don't," Matt said that "dumping a clean bucket of water over my head seemed a little crazy."
