San Francisco 2009 Pillow Fight

Every year on Valentine's Day, a few thousand drunk or lonely or rageful, jovial, disinhibited people gather in Justin Herman Square to pillow-fight a bunch of strangers.

The event is not without controversy, as last year's feather cleanup cost the city many thousands of dollars.

So grab your latex pillow and come on down. If you aren't getting laid on Valentine's day, at least you can get gobsmacked by a pillow!
