a few years ago,
some friends and i used to play a fun game called "cover yourself in blood and zombie makeup and set up elaborate zombie attack tableaus on the the side of the road late at night and then chase cars when they slow down."
this would be the time that we set up a couple of shitty cameras and filmed it.
we were covered in fake blood and wounds, but of course that didn't show up on nightvision.
(nothing really happens for the first minute or so, about 1:10 is when the real fun starts)
