I've been up to my eyes in work and stress but this is too amazing not to post. Improv Everywhere is a NY based group that organizes random improv. One was dressing everyone up in Best Buy blue shirts and khaki pants and have them wander around the store. Another was getting 200 people to freeze in the middle of Grand Central Station for 5 mins. And they're infamous for the no pants subway ride.
This, however, is hands down the most awesome thing I've ever heard of. In short they turned a little league game into a major league one complete with vendors, a Jumbotron, and a bunch of other surprises.
Enjoy the best game ever.
