Can't find a video of it, but there have been research where volenteers would get a small reward if they get of the plane quicker. Chaos, people climbing over chairs, people getting jammed at the door and a lot slower evacuation...

Evactuation from a plane (but also other things) is a very complicated study. The behavior of people really depends on the design of the aircraft, behavior of other, trained crews and how immediate the danger is felt by people.
