Improv Everywhere

A while back I added the Improv Everywhere website to my "Links I Like" sidebar. I don't remember why I wound up at the site in the first place, but I'm sure glad I landed there. The latest "prank", the Human Mirror, is so ingenious I just had to throw this post up to urge y'all to check it out. But be careful. I found myself addicted to the site and thus reading through one after another of the missions until I was bleary-eyed and my ribs hurt from laughing...
