Pillow-fight club!

The first rule of pillow-fight club...is that you can only use feather stuffed pillows. And unlike it's namesake, you're free to talk about it all you want. The way it works is you find out about the pre arranged venue, bring your pillow and at the exact moment everyone launches into a massive pillow fight. It's a great way to vent your frustration, and no one gets hurt....unless Barry Bonds makes an appearance.

A recent Pillow Fight Club experience saw 1000 people fight it out in San Francisco and in London, lasting just over an hour.
