It's like Improv Everywhere with a purpose.Look, I don't mean to hate on Improv Everywhere. I love their stuff. But sometimes, when I'm watching their videos of pantsless subway rides and impromptu produce-aisle musical numbers, I think, "You're making people kiiiiind of uncomfortable, and what is the point?"This.This is the point.This is something people should be uncomfortable about.This is flash mob with a purpose.Standing ovation, Ferguson protesters. Standing ovation.
