Celebrities: they’re just like us…except that they don’t use toilets. The great toilet boycott has started.

At least some of them. Movie star Matt Damon, who does a lot of humanitarian work on the side, co-founded water.org, an organization devoted to bring clean water to the 2.5 billion people worldwide who lack sanitation, including 800 million who don’t have access to clean drinking water.

To promote his cause, last month Damon publicly announced that he would refuse to use a toilet until everyone in the world enjoys the same water privileges as first world nations.

Today, more celebrities joined the crusade, including Jason Bateman, Jessica Biel, and Josh Gad. (No word on exactly how they’ll go about their “business.”)

Obviously we care a lot about toilets and bathrooms, not just as reading rooms, but as a privilege that many of us enjoy as a modern health marvel and take for granted. If you, like Damon, think that access to clean water and sanitation should be a right, check out water.org and strikewithme.org to see how you can help…or even take the pledge yourself.
