Pillow Fight!
So, you’ve heard of flash mobs, right? They are what happens when a bunch of people coordinate with a bunch of other people (usually extending to friends of friends of friends of friends, so in reality, a bunch of strangers) to all show up at one place at the same time and, usually, do something kind of strange, then disappear. Well, there was something like that in San Francisco on Valentine’s Day. Except this time, the weird thing everyone did was have a pillow fight. You’re talking hundreds of strangers, showing up in a square in downtown San Francisco, and proceeding to beat the hell out of each other with pillows, then walking away, leaving nothing but a mound of feathers to prove it ever happened. Oh, and these photos on laughingsquid.com. You want to know about the true benefit of the Internet? This is it. Mass-coordinated pillow fights.
