ultimate in time wasting

You and a randomly selected partner view a series of images for two minutes, for each one typing in keywords to describe said images. When your answers match, you score points and move on to the next picture. That's about it. It sounds really boring and stupid, but seriously, it's not. Except for maybe the stupid part. And while you may be wasting a ridiculous amount of time - it's fucking addictive! - know that you're further refining the google images search, a tool which has not only provided hours of amusement on gchat, but which has been instrumental in locating pretty much every picture of a half-naked man on this blog. And for that I am infinitely thankful.
