One day two blondes were out in the woods. The first blonde was on one side of a river, and the second on the opposite side. The first blonde wanted to get to the other side of the river and so she called to the other blonde for help. The second blonde had a flashlight and wanting to help, said, “I know! I’ll shine the light of my flashlight across the river and you can walk across on the beam.” The first blonde said, “ Are you crazy? I get half way across, and you turn off the light!”
