There is this blog called Improv Everywhere. The basic premises of this blog is that a group of people go out into the world and follow through with an improv idea. Their most recent improv event was welcoming back total strangers in an airport. The video of this just made me smile. (On a side note Mi Prima and I thought this would be a fun idea, unfortunately the Portland Jet Port is small, and chances are we might actually know the person getting off the plane).
