Improv everywhere

Last week's This American Life is just brilliant. Act II is about the troup Improv everywhere. They create unrealistic improvised situations in daily life situations. In one of the skits they had a group of 12 volunteers looping a sequence of events in a Starbucks. One guy would spill the water, dry it off, go to the bathroom and the repeat. A couple would come in, get in an argument and leave. Some other guy would just go through the store listening to a boombox. And so on. Each actor would repeat the sequence over and over, until customers in the shop realized what was going on. After a few loops the crowd started to predict the future, call relatives to let them know about the "Groundhog day" experience. They have a lot more stories and they get even better (or worse). Absolutely brilliant !!!
