Do you work in an office? Do you like wasting time? How about hitting people in the face with beachballs? If you answered yes to any of these, I hereby command you to investigate Faceball, invented at Flickr, but now sweeping offices worldwide.

The game is pretty simple -- two people sit in office chairs, ten feet from each other, and throw beachballs at each other's faces. No ducking is allowed. If you score a face-hit, you keep throwing until you miss, gaining points all the while. After an agreed-upon number of rounds (generally five), the player with the most points wins. (If this explanation isn't enough, check out the video introduction on the Faceball site - scroll down.)

Faceball is all about documentation -- because Flickr staffers invented it, they present tons of photos of beachballs hitting faces. The quintessential Faceball photo shows a beachball impacting a person's face -- silly and a bit humiliating. Faceball co-creator John Allspaw explains that the game was invented "to relieve work stress and replace it with humiliation and embarrassment."
