The Magical Porta-Potty Keeps On Giving [Video]

Improv Everywhere organized a series of surprises at the recent Governors Ball music festival at Randall's Island Park in New York for when concertgoers opened a special porta potty.

What will be behind the door of the magical Porta-Potty when you open it? It could be a Mariachi band, it could be a Gospel Choir.

But what if you REALLY REALLY have to just go to the damn bathroom? I guess you're just S.O.L., aren't you?
