We're not sure what happened to cause all this and we wish the video started sooner. Either that, or we totally missed what happened. We think it involves the woman walking down the road.
We would venture to guess the second woman got out of her car in order to punish the driver in front of her for doing something mean to the woman walking away, since she seems to point to the walking woman. Whoever or whatever started it aside, the driver puts a hilarious end to it when he chucks her crutch into the field.
