The wonderful Improv Everywhere just posted the report from its 6th MP3 Experiment, where 2,000 people all got together and listened to the same instructional MP3. It looked like a crazy amount of fun.

You may be familiar with some of Improv Everywhere's other pranks, such as Frozen Grand Central and the No Pants Subway Ride, but the annual MP3 Experiment is one that looks like it may be the most fun to participate in. I mean, come on, watch that video and tell me everyone doesn't look like they're having a blast. [Improv Everywhere]
