For this year's Governors Ball Music Festival in New York, the Improv Everywhere group decided arranged an unforgettable prank that involved a highly unusual mix of port-a-potties,a mariachi band, a Gospel choir, and Bollywood dancers.
The video captures a number of concertgoers opening the "magical" port-a-potty door only to be surprised by a seemingly endless stream of performers marching out and playing music.
