Electric Dog Fence Race
So you have an electric dog fence installed in a zigzag formation across an area, say for 10 yards or 20 yards long and 5 yards wide, and you have two members of the jackass crew strap a electric dog fence collar on each of their legs. One collar per leg and one on each arm. Also you have a bark-shock collar, one that shocks a dog when it barks, strapped on their necks. You have them race from one side to the other and see who can get through the electric course first. As they run through the invisible fence they will get shocked by the fence nd then scream and be shocked again.
