OK, so Matt Damon‘s “I will not go to the bathroom” promo spot for the advocacy group Water.org and his campaign site Strike With Me is more than a little dumb. But it does include a couple of things missing from most PR campaigns: humor and celebrities who still have a little bit of credibility left. Before the lame jokes begin, it also makes some very serious points in a lighthearted way.

For example, we didn’t know that more people have access to cellphones than toilets, that women around the world spend the equivalent of 200 million work hours collecting water every day or that World Water Day is a real thing. Oh, and we can think of a certain Florida Senator who would make a great spokesman for clean drinking water right about now.
