There was a blond guy who joined the army. Everytime they did a run, he would always be falling behind. A war had started, so they were in combat. And again the blond buy was falling behind. So the captain walked over to him and said, "You see that canyon over there, I have this new high tech flashlight, and the rope is like a beam, and I want you to climb over the canyon with it." The blond guy grabs for the beam and says, "Oh I know your scam! I'm going to get half way and your going to shut off the light!"
